Introduction

The DeLuxe Stitcher M7 Stitcher Machine is a single-head stitcher designed to accommodate both light and heavy-duty work, stitch both flat and saddle and is world renowned for its ability to reliably stitch any thickness of stock from 2 sheets to 7/8”

(22.2mm).

The recommended wire sizes to be used on the M7 are: 24 to 28 gauge round wire and

20x24, 20x25 and 21x25 flat wire. These wire sizes can be used without changing any parts in the Stitcher head. However, for heavy flat work it is recommended that the special Flat Work Driver be substituted for the Standard Driver.

The M7 is easily adjusted from saddle work to flat work by tilting the 5 1/2” (14cm) x 26” (66cm) work table. An adjustable work guide and adjustable work stops areeasily attached to the work table and provide for accurate registering of flat work for uniformly spacing the staples. In addition a work table extension is provided to accommodate larger sizes of work to be stitched. The M7 is the most versatile of all single-head machines.

The M7 is foot-switch operated and belt driven by a 1/2 HP motor, making possible operating speeds up to 125 stitches per minute. The motor is mounted on an adjustable bracket which can be raised or lowered to adjust driving belt tension. The machine driving mechanism is thoroughly shielded, preventing the possibility of personal injury.

The M7 has a 14” (35.6cm) throat depth for both flat and saddle stitching. The work table is approximately 34” (86.4cm) above the floor and there is approximately 1/8”

(3mm) clearance between the top of the work to be stitched and the protective guarding around the stitcher head.

The M7 weighs 340 lbs. (154.5 kgs) net and the shipping weight is approximately 410 lbs. (186.4 kgs). With the table installed, the M7 requires about 31” (78.8cm) x 35”

(88.9cm) of floor space.

Because of the length of the work table, the M7 must be secured to the floor to meet

CE stability requirements. Sound level readings at the normal operator position are approximately 70 dB.

Figure 1 - Assembly

Assembly (Figure 1)

Some assembly is required upon delivery of the M7 Stitcher. You will need a flat screwdriver, 5/32” and 3/8 hex head wrenches and a 9/16 open end wrench. Line up the hole in the Wire Straightener

Assembly (M7321A) with the screw hole in the Head Mounting Plate (G30092). Secure the assembly with the Socket Head Cap Screw (UA6816.2). Assemble the Wire Spool Bracket (G30120) to the back of the Head Mounting Plate with two (2) Screws (UA3806.16) inserted through two (2) 1/4

Washers (PW14). Remove the Flat Washer (PW38), the Lock Washer (LW38) and the Plain Nut

(HN3816) from the Spool Stud (7693) and insert it into the back of the Wire Spool Bracket. Secure the Spool Stud by replacing the Washers and the Nut. Loosen the Thumb Screw (P2731) in the Set

Collar (7691) and remove it and the Tension Spring (7690) from the Spool Stud. Slide the Wire Spool over the Spool Stud, making sure that the Flat Washer (PG10271) and the Large Spool Stud Washer

(2245) are between the Spool and the Wire Spool Bracket. Also verify that the wire payoff is identical to the payoff in Figure 1. Improper wire payoff will result in poor stitching. Slip the Plastic Washer

(M11009) over the Spool Stud and replace the Tension Spring and Set Collar. Apply slight pressure on the Set Collar, pre-loading the Tension Spring, then tighten the Thumb Screw in the Set Collar until secured in position. A properly set Tension Spring will cause the Wire Guide Spring (15150LA) to flex but not actually hit the wire spool.

7

Insert the Wire Guide Spring (15150LA) into the top of the Wire Straightener Assembly. Loosen the two (2) Set Screws (38) and remove the two (2) Work Table Swivel Pins (203B) from the Clincher

Mount Assembly (G30044A). Line up the holes on the underside of the Complete Table Assembly

(7656A) with those in the Clincher Mount Assembly and replace the Swivel Pins. Secure the Swivel

Pins by tightening the Set Screws in the Table Assembly. With the Table Assembly in the flat position, mount the Work Guide (M7201B) with two (2) Thumb Screws (63). Slide the two (2) Work Stops

(7423) onto the Work Guide and tighten the Thumb Screws (425) to secure in the desired position.

Note: Do not allow the Work Guide to interfere with the stitcher head as this will cause damage to both.

Electrical power is provided through the attached Power Cord (86243 or 86244) and should be connected to an appropriate supply outlet but do not power on the machine until all safety checks have been made. The machine has to be turned over manually to verify that the stitcher head is operating freely before the M7 can be operated under power.

Note: Be sure to level the machine and secure it to the floor before use.

Belt Guard Removal and Assembly (Figure 2)

The plastic Belt Guard (7676) must be removed before the M7 can be turned over manually. To remove the Belt Guard, remove the Retaining Screw (G30163) from the top of the Guard (on International models only). Press on one side tab while prying out the locking face, at the top of the Guard. Next, pull down slightly on the top of the Guard to release the bottom tab. The Guard will now be free to lift off from around the Belt Guard (7675).

To reassemble, interlock the bottom tab and pull up slightly on the Guard to interlock the side tab, then squeeze the two halves of the Guard together to lock the remaining tab. Reassemble the retaining screw at the top of the

Guard (on International models only).

Adjusting for Thickness of Work (Figure 5)

Unlock the Hand Wheel (G30128) by turning the Adjuster Crank Lock (G30158) on the Adjuster

Crank Housing (G30099) counter-clockwise. Turn the Hand Wheel clockwise until the Adjuster

Spool (G30119) is raised sufficiently to allow a sample of work to be inserted between it and the lower Adjuster Stop (G30103). The thickness gauge is located on the right-hand side of the machine if you are looking from the front of the stitcher. With the work held flat in a horizontal position, turn the Hand Wheel counter-clockwise until the work is firmly clamped between the Adjuster Spool and the lower Adjuster Stop. Turn the Hand Wheel back clockwise just enough to allow the work to be withdrawn from the Adjuster Spool, then return the Hand Wheel to the setting at which the work was clamped.

Anytime the thickness of work changes, a sample should be tested in the M7 so no serious damage is caused to the machine. If the machine is operated on work thicker than it is set to handle, damage will result and the stitcher machine will not operate properly.

Note: When adjusting for more than a slight decrease of work thickness,

WARNING

Recommended Wire Sizes (Figure 6)

The wire sizes to be used on the M7 are listed below. Though all of the listed wires can be run without changing any parts in the Head, it is recommended that the 7089F Driver be substituted for the 7089E Driver when doing heavy flat work . For instructions on how to change the Driver, see page 28.

Two types of Clincher Points are provided with the M7. When running round wire, use the Clincher

Points with part number 7257B.

When running flat wire, use the Clincher Points with part number

7024B.

When stitching stock over 20# it is recommended that a high tensile wire be used, which is available in 21x25, 20x24 and 19x21-1/2 flat wire sizes. The high tensile wire may cause increased wear on certain parts.

For any stock over 33# or coated stock it is recommended that 19x21-1/2 flat wire be used. In order for the M7 Stitcher to accommodate this size wire, the following parts must be exchanged: Bender Bar

Assembly (7086BA), Driver (7089G), Wire Guide Assembly (7111BA), Wire Holder Slide (7130B),

Wire Straightener Rollers (7277B) and the Clincher Points (7024C). See pages 57 and 58 for an exploded view of the parts neccessary for the 19x21-1/2 flat wire conversion.

Troubleshooting (Figure 14)

The following is a brief list of problems and solutions which should cover the majority of situations encountered when stitching with the M7. The quality and quantity of work that can be produced with the M7 Stitcher is dependent upon the operator making all adjustments as accurately as possible and carefully maintaining the machine. The cause of staple imperfections usually can be traced to inaccurate settings or normal wear of moving parts. In the event of problems of this nature occurring, the operator can, by referring to the following troubleshooting chart, quickly locate the solutions.

problem : Stitch quality is poor.

solution :

1. Check the Wire Cutters (7102) for wear to see if they need to be reversed or replaced.

2. Check for straightness as the wire feeds through the Head.

problem : The machine will not complete a cycle, both under power and manually.

solution :

1. Make sure the compression setting is correct. If not turn the Hand Wheel (G30128) clockwise to raise the stitcher head.

2. The Supporter (7100A) may not be freely moving between the sides of the Bender Bar (7086A) which can be corrected by bending the arms of the Supporter Link (7100) slightly but most likely the

Supporter will have to be replaced.

3. The Left (7095) or Right Wedge (7208) may not be seated completely. Remove the Face Plates and gently tap each of the Wedges in until flush with the edge of the Face Plates.

problem : The wire is being cut but dropped before it can be formed.

solution :

1. Check wire straightness.

2. If the problem continues, check to see if the inside corners of the Swivel Operating Sector (7146) are still intact and replace if necessary.

3. If there is play between the Sector and the Swivel Operating Lever (7142), replace the Sector.

4. The Swivel Operating Lever Spring (7226) may need to be replaced if not offering enough resistance.

5. Make sure that the wire is feeding straight from the Wire Spool, if not adjust the Wire

Straightener Rollers (7277).

6. Check for a damaged Swivel Hook (7232) and/or Swivel Hook Spring (7234).

problem : There is inconsistent wire draw shown by varying lengths in the staple legs.

solution :

1. Check to see if the wire is hitting the Swivel Assembly (7138A) and adjust for straightness.

2. Premature wearing could be caused by restricted movement of the Wire Grip Holder (7133A) between the Face Plates which in turn causes inconsistent draw.

19

3. The Wire Cutter Slide (M7107A) may also be too tight in the Left Face Plate (M7082A) causing inconsistent cutting. (The Head should be disassembled, cleaned and lubricated).

4. Check to see if the Wire Feed Shoes (7154) are worn and need to be replaced.

5. The wire is not properly fed through the Wire Guide Spring and the Straightener Rollers; correct.

6. Check to see if the Straightener Rollers (7277) are crimping the wire and adjust.

7. The Moveable (7136) and/or Stationary Grip (7132B) may be worn and have to be replaced.

8. A weak Wire Grip Spring (7134B) will not position the Moveable Wire Grip correctly; replace.

9. The Grip Operating Lever (7176) and/or the Grip Operating Lever Slide (7178) may be bent or broken. If this is the case, these parts should be replaced.

problem : The wire is being bent, not cut or it is jamming within the head.

solution :

1. First check to see that the Wire Cutters (7102) do not have to be reversed or replaced.

2. Make sure the Wire Cutter Retainer (7109) is secure within the Wire Cutter Holder (7103A), if not make a notch in the Wire Cutter Holder above the Retainer with a screwdriver. This will secure the upper Wire Cutter (7102) in position.

problem : The wire is being pulled back out of the Wire Cutter Holder (7103A) after each stitch.

solution :

1. The Grip Operating Lever (7176) is broken or damaged and needs to be replaced.

2. The Wire Feed Shoes (7154) are worn causing both of the grips to not react properly and need to be replaced.

problem : Wire is accumulating in the Swivel Assembly or stitches are only partially formed.

solution :

1. If the Swivel Assembly (7138A) sits too far out from the Bender Bar the stitch will not be formed or only partially formed, adjust the Set Screw (38) in the Door Assembly (7137A).

2. If the Driver Bar Latch (7094) is not activated properly, the Driver (7089E or 7089F) will move the

Swivel Assembly out of the way before the stitch is formed. Bring the stitcher head down for large scale adjustment or tap the Left Driver Bar Wedge (7095) in slightly for fine adjustment. See pages

11 and 29.

When stitches are defective, the operator can compare the staple produced with the illustrations in the chart. By carefully following the information given in the chart, the operator can quickly resolve the problem, keeping downtime to a minimum.

Maintenance

Lubrication (Figures 15 and 16)

Your M7 Machine has been fully lubricated at the factory, but regular preventative maintenance will result in superior performance and a longer life of the machine. Machines that are in constant use should be lubricated daily where as machines that are only operated periodically should be lubricated just prior to use. Usually only a drop of oil is required at each lubrication point in the stitcher head.

Care must be taken that those parts of the machine that contact work remain free from oil.

Lubricate regularly instead of excessively.

Excessive oiling will result in work becoming oil-spotted. After lubricating the machine, wipe off any excess oil. Use one drop of any standard S.A.E #10 oil in the following lubrication points:

• the oil hole in the Wire Feed Slide (7112A)

• the oil hole in the Wire Cutter Holder

(7103A)

• the oil hole in the Swivel Operating Cam

Roller Stud on the Driver Bar Assembly

(7091A)

• the oil hole in the Door Assembly (7137A)

leading to the Swivel Operating Lever

(7142)

• the opening in the Swivel Bushing (7139A)

• the rails of both the Left Face Plate

Assembly (M7082A) and the Right Face

Plate Assembly (M7083A)

• between the Moveable Wire Grip (7136) and

the Fixed Wire Grip (7132B)

• on the Rod in the Driver Bar Assembly

(7091A) and on either side of the Driver

(7089E) and on the Driver Bar Latch (7094)

Always disconnect the power supply before making any adjustments or servicing the stitcher.

 WARNING

Cleaning

In addition to proper lubrication, routine cleaning is important for the maintenance of the M7

Stitcher Machine. The following areas should be cleaned every three months:

• Swivel Assembly (7138A) : remove and wash in an oil-dissolving solvent, dry and relubricate.

• Swivel Bushing (7139A) : clean inside the Swivel hole.

• Anywhere that dust, oil or pieces of wire and paper have built up - for example: the Grip,

Clincher Points and around the Wire Straightener Rollers.

• V-Belt (850730) : remove and reverse to check for cracking; a belt dressing may be applied periodically to extend the life of the belt. Also check for the proper tension in the belt.

Ordering Spare Parts

In time, you will need to replace some parts in the M7 Stitcher Machine. To do this locate the DeLuxe

Stitcher part number in one of the following diagrams and contact your Graphic Arts Representative to order the replacement by part number, description and quantity.

23

Always disconnect the power supply before making any adjustments or servicing the stitcher.



WARNING

Replacing Spare Parts

The operator should periodically inspect all moving parts for signs of wear and when required, replace the worn parts. The Wire Cutters (7102), the Wire Grip (7132B) and the Driver (7089E) have been designed with duplicate cutting and gripping surfaces. When the original cutting or gripping surfaces show signs of wear, their position in the head can be reversed to provide a new working surface, which lengthens the life of the part. The following are some of the more common wear parts which will need to be removed and replaced in your M7 as well as step-by-step instructions to replace them.

Head Disassembly (Figures 17 & 18)

Some common wear parts are easily exchanged without removing the Face Plates from the M7

Stitcher Machine such as the Wire Cutters (7102), the Fixed Wire Grip (7132B), the Driver (7089E or 9089F) and the Clincher Points (7024B) . ( See pages 26 through 29. )

But most wear part changes require the disassembly of one, if not both Face Plates (M7082A and

M7083A). General disassembly instructions will be given first then a more specific description for each common wear part will follow.

WARNING

Removing and Replacing the Wire Cutters (Figure 19)

The Wire Cutters (7102) have two cutting edges, each of which may be used by reversing ends and the position of the Cutters in the Wire Cutter Holder (7103A). When the

Cutters are worn a burr is formed at the end of the cut piece of wire causing poor stitch quality. Check an unformed piece of wire from the Swivel Assembly. A properly cut piece of wire will be smooth on both ends.

If it is not, the Cutters have to be reversed or replaced. To remove and replace the Cutters proceed as follows:

Open the stitcher Door Assembly (7137A) as previously described on page 10. Tap on the Wire Cutter Retainer (7109) to raise it out of the way and slide the upper Wire

Cutter out from the Wire Cutter Holder.

7086A the Feed Grip. In the tunnel created by the slots on the back of each Wire Feed Shoe, try Figure 24 - Removing the Wire Feed Shoes to insert the Driver Bar Assembly. (Make sure the side of the Driver Bar Assembly with the Swivel Operating Lever Cam Roll (7194) is on the same side as the notch in the Feed Grip. Refer to

Figure 24

for the correct orientation as this is critical. If this proves unsuccessful, file the small slot on the rear of both the Wire Feed Shoes with a 5/32" file so that the Driver Bar Assembly can be twisted between them while they are in place in the Feed Grip. The fit should be tight but still able to be adjusted by hand. A fit that is too tight will cause the brass Shoes to wear prematurely and a loose fit will cause inconsistent draw or cause the wire to be pulled from the Grip. When the fit is accurate, insert the Wire Feed Shoe Spring and twist it so the ends of the Spring are facing towards the small holes in the ends of the Wire Feed Shoes.

Insert one end of the Wire Feed Shoe Spring into the hole in one of the Wire Feed Shoes. Compress the Spring to get the other end into the hole in the other Shoe.

Clutch-Brake Maintenance

Always disconnect the power supply before making any adjustments or servicing the stitcher



WARNING

This stitcher is equipped with a solenoid actuated, continuous trip, wrap spring clutch-brake unit.

It is a dependable device and seldom needs service. But should a malfunction occur, the following information is a service and troubleshooting guide for the maintenance of this unit.

Actuator

The actuator is a simple, straight-forward mechanical linkage. When the actuator does not trip, the following checks should be made. Refer to Figure 27 for more details.

Problem

No power to the Coil

Lack of continuity in the

Coil Windings

Cause and Remedy

Check all wiring and switching in the

Clutch actuating system.

Replace the Coil (850998 - 230 VAC or 850999 - 115 VAC)

Mechanical binding of

the Plunger

The Coil may have shifted or the Plunger end may have mushroomed due to striking the Backstop. In the latter the Plunger may be filed to its true diameter.

Insufficient clearance for the

Actuator over the Stop Collar

Adjust the Linkage as needed

Actuator loaded by the

Stop Collar so hard that the

Braking force is exceeding the limits of the Brake or the Differential setting of the unit is too close

Actuator cannot be pulled by (see Figure 30 for instructions)

the Coil.

Figure 27 - Actuator Checklist

34

Clutch and Brake Springs

With the brake engaged (full limit of output), the input hub should be free to rotate by hand. With the clutch engaged, the input and output hubs should rotate together. If the unit does not rotate in either of these modes, the clearance between the hubs of the unit on the shaft may have been disturbed or damaged. See Assembly/Disassembly instructions for re-adjusting.

Listed below are additional checks to be made if the clutch does not function correctly. Refer to

Figure 28 for details.

Problem

Clutch Brake does not drive but Input Motor turns

Clutch Brake jams and stalls Input Motor

Output does not repeat stopping point

Cause and Remedy

1. Drive Spring (850889) may be broken at the crossover point from an overload caused by a jam.

Replace the Spring and check the Hubs (851321 or

850892) for damage.

2. The Control Collar (850888) may not snap forward because of foreign matter is restricting movement.

Clean the unit.

3. Actuator Assembly does not pull in. (Figure 28)

1. Spring tang broken off Drive Spring not allowing the Clutch to disengage while the Brake is engaged.

Replace the Drive Spring.

2. Clutch output is bound up. Check the clearance between the Output Hub and the Brake Hub.

3. Completely out of adjustment caused by losing an internal Spring tang. Replace Spring.

1. Not enough inertia to actuate Brake.

2. Tang broken off the Brake Spring.

Replace the Spring.

3. Adjustable Collar Locking Screw may be loose allowing Adjusting Screw to rotate.

Figure 28 - Clutch and Brake Spring Checklist

35

Disassembly (See figure 29)

To disassembly the Clutch-Brake unit (850677 or 850678) it will be necessary to remove the Drive

Pulley (7678) from the stitcher by removing the V-Belt (850730), Retaining Ring (P7863), and

Clutch Anchor Screw (7681). Disconnect the Ground and Solenoid wires, and swing the anchor strap

(FC9656) clear of the Drive Pulley Assembly and slide it off of the Drive Shaft. Remove the three

(3) Screws (UA4812.7) connecting the Drive Pulley to the Clutch-Brake unit.

When disassembling the Clutch-Brake unit, always mark the Spring Tang locations with reference to which slots they go in if the same Springs are to be used for reassembly. To disassemble the

Clutch-Brake unit, proceed as follows:

Release the Actuator Lever so that the Clutch is engaged and the Brake is released. Remove the

Retaining Ring and the Shim Washer, if any, from the Input Hub (851321) end. Remove the Input

Hub by rotating opposite to the drive direction. Remove the Retaining Ring and the Shim Washer, if any, from the Mounting Plate end.

Remove the Output Shaft Springs and the Control Collar (850888) Assembly by rotating the Output

Shaft (850891) in the drive direction. (Do not disassemble the brake Hub (850892) from the

Mounting Plate. (850890)) Remove the Control Collar from the Output Shaft and the Spring

Assembly by extracting toward the Brake Spring end.

Assembly (See figure 29)

Replace the Clutch (850889), Brake (850889) and Anti-Back (850962) Springs as required. Assemble the Springs concentric and square to the Output Shaft.(850891) Assemble the Control Collar over the

Output Shaft and Spring Assembly by inserting it from the Brake Spring End (it will be necessary to extend the Brake Springs using long nose pliers.) Place the Brake Spring Tang in any one (1) of the nine (9) Control Collar slots at random.

Assemble the Output Shaft, Springs and Control Collar assembly to the Mounting Plate Assembly by rotating the Output Shaft in the drive direction. Assemble the Retaining Ring (850886) to the Output

Shaft at the Mounting Plate end (the smooth surface facing the Brake Hub.) Check the end play between the Hub and the Retaining Ring with a feeler gauge. There should be 0.004” to 0.010” end play. Use a Shim Washer to adjust if necessary.

Rotate the Output Shaft in the drive direction until it reaches a full brake position. With the Clutch

Spring Tang NOT in slot, insert the Input Hub (851321) by rotating opposite to the drive direction.

Select one (1) of ten (10) Control Collar slots for the Clutch Spring Tang that will provide a 0.38” to

0.50” circumferential overtravel of the Control Collar when released.

36

Note: At this point it may be necessary to reselect one (1) of the nine (9) Control Collar slots for the

Brake Spring Tang (release Actuator Lever, remove the Clutch Spring tang from the slot, then move

Control Collar axially toward the Input Hub end and rotate it opposite to the drive direction to pick up the next slot). Continue to select Control Collar slots until the 0.38" to 0.50" specification is achieved.

Assemble the Retaining Ring to the Output Shaft at the Input Hub end (the smooth surface facing the

Input Hub). Check the end play between the Input Hub and the Retaining Ring with feeler gauge.

There should be 0.002" to 0.003" end play on the Input Hub.

Reassemble the unit to the machine.

Note: After the Clutch is assembled to the machine, the Clutch Plate should be free to float on bearing

- the Anchor Strap is only there to prevent rotation of the plate.

Lubrication

The clutch-brake unit is designed with the bearing parts made from sintered metal that has been impregnated with oil and normally do not need to be re-lubricated. In cases where there is severe duty, the unit may be re-oiled or flushed out with minimal or no disassembly by using a light bearing oil as used in manufacture (Shell Bearing Infusion Oil #33). If disassembly of the unit for cleaning and oiling is necessary, follow the detailed disassembly instructions to the point needed, flush and wipe parts in the oil to be used for re-lubrication. Do not use solvents to clean the parts. To get more cleaning action for the oil, it may be heated while cleaning the components, but bring the parts back to ambient temperature submerged in cool oil.

Coil Replacement

Place the spring onto the plunger with the narrow end towards the actuator. Slide the solenoid onto the actuator and plate assembly. Assemble the solenoid to the plate assembly with the cap screws and washers. Do not tighten more than finger tight.

Energize the coil and adjust the gap between the actuator and the top of the collar stop to 0.015" to

0.030" by sliding the solenoid assembly.

Note: Push the collar toward the actuator to allow for collar movement. Tighten the cap screws.

Control Collar Adjustment (Figure 30)

The stopping position of the head can be changed if necessary by adjusting the position of the stop cam on the control collar sleeve.

Turn the machine manually until the driver is in the desired stopping position, the proceed as follows:

Work the Retaining Ring (850886) out of its groove and slide it forward on the Input

Hub (851321). Slide the cam of the Control

Collar Assembly (850888) off of the splines, rotate to align the collar stop with the actuator and slide the cam back on the splines. The actuator pawl will have to be held clear during this operation. Slide the retaining ring back into its groove.

Make sure brake is locked up before proceeding, to insure the proper stop point.
