2.0 INSTALLING A NEEDLE IN THE INNOVA

The Innova quilter is capable of sewing with various needle types and sizes. ABM recommends the use of Groz Beckert, 134SAN11 needles in either a size 16 or 18.

The main difference between a size 16 and 18 is the diameter of the needle section that penetrates into and through the material and the size of the needle eye. The size 18 needle is considerably larger than the 16 and as a result, the 18 is a much stiffer needle. The stiffness of the needle helps reduce needle deflection. Deflection is the largest cause of sewing problems with a machine that stitches in all directions

– left, right, forward and back. Unlike standard sewing machines equipped with feed dogs that only sew in one direction (or possibly two if back tacking), quilting machines, like the Innova, sew in all directions and benefit greatly from using the largest possible needle. However, the user must decide on the appropriate size needle for the application. Size 18 needles will produce a larger hole that many threads will not fill.

As a rule of thumb, ABM recommends using size 16 needles in the Innova. If skipping is encountered while sewing a product, and you do not have the time to inspect or adjust the hook, install a size 18 needle in the machine to alleviate the problem quickly. Then when you have more time available, install a size 16 needle and adjust the needle and/or hook as needed.

The single largest service issue ABM has faced with the Innova is incorrect installation of the needle in the needle bar. In most cases, the needle is installed facing the wrong direction. However, there have been some instances of the needle not being inserted all the way into the needle bar. First, we will look at the correct orientation of the needle on the machine.

Sewing machines will only sew with the needle installed in the correct direction. However, round shank needles, like the ones on most quilters can easily be installed incorrectly. In an

Innova, the scarf of the needle must face toward the machine foot. When the needle is installed correctly, the thread groove should face directly toward the top fabric and liner rollers. When viewed by standing in front of the Innova, the operator should be able to see through the eye of the needle.

In some instances, the needle has not been inserted into the needle bar completely. Upon close inspection, a portion of a hole can be seen just above the needle bar thread guide. When inserted completely, the needle will contact the top of this hole. It may be easier to view the first time by removing the needle set screw and needle bar thread guide. Additionally, if the needle is difficult to hold, it may help to use a set of needle nose pliers. If pliers are used, pay careful attention not to snap off the needle in the needle bar.

13.0 ADJUSTING THE HOOK DRIVE MECHANISM – BELT / GEAR

The INNOVA long arm quilting machine is equipped with either a belt or composite gear driven hook assembly (See Figure 13.1). On a belt drive system, the main drive shaft turns the large center pulley which drives the belt around two idlers and the small upper hook drive pulley. The gear drive system consists of a composite gear mounted to an aluminum hub that turns the small pinion gear on the hook drive shaft.

Figure 13.1 - Hook belt drive and gear drive assembly

Though most machines will never require adjustment, it may be necessary to service the belt or gear drive assembly. This service can be preformed with standard hand tools including a flat blade screw driver and Inch hex key set. To adjust the belt, remove the guard plate held in place by the four screws on either side of the machine base. Upon closer inspection, the belt drive assembly consists of four pulleys. For adjustment purposes, we are only concerned with the lower two idler pulleys and the tension plate (See Figure 13.2).

Figure 13.2 – Idler pulleys and tension plate

The tension plate allows for adjustment of the tension of the hook drive belt. If the tension is too loose or too tight or if the tension plate is misaligned, an audible “chirp” is usually heard from the machine at certain speeds. The various procedures are as follows:

NOTE: Before performing any belt drive adjustments, remove the needle from the needle bar and remove any loose clothing or jewelry. Additionally, remove the bobbin case from the hook and clean all thread, dust and debris from around the hook assembly.

Adjusting Belt Tension:

Referring to figure 13.2, loosen, but do not remove, both screws labeled B. Using the correct hex key, tightening screw C will tighten the belt (move the hex key from left to right).

Loosening screw C will loosen the belt (move the hex key from right to left). Retighten the two screws B and run the machine in manual mode to check for proper tension. Do not over-tension the belt. A small amount of deflection should be present when you press in on the belt between the lower idler and upper hook pulleys. When proper tension is achieved, install the guard plate into the machine base.

Adjusting Tension Plate Alignment:

Referring to figure 13.3, during the belt tension procedure, it is possible for the tension plate to become misaligned. This misalignment may result in an audible “chirp” from the belt. To correct the misalignment, loosen the two screws labeled B in figure 13.2 and lightly pry between the tension plate and hook assembly housing with a small screw driver. Retighten the two screws labeled B and confirm proper operation of the belt drive. When proper alignment is achieved, install the guard plate into the machine base.

Figure 13.3: Tension plate misalignment

Adjusting Belt Tracking:

Tracking adjustments are no longer needed with the addition of flanged pulleys on the tensioner.

Note: It is normal for the belt to “walk” in and out on the pulleys a small amount when the machine is running.

Adjusting Gear Lash:

The lash, spacing between two adjacent gears teeth, is adjustable. To adjust the lash, slightly loosen but do not remove the four lash adjustment screws in figure 13.4. The screws should be snug but loose enough to allow the whole aluminum hook housing to move if lightly tapped with a rubber mallet.

Figure 13.4 Gear drive assembly – lash adjustment screws

Tap the housing up to increase lash or tap the housing down to reduce lash. Too much lash will cause the hook to wiggle excessively and timing will be sloppy. Not enough lash will cause the gears to whine and will make the machine difficult to turn.

Make sure the needle is centered in the needle plate hole before re-tightening the lash adjustment screws. When proper lash is achieved, install the guard plate into the machine base.

14.0 SEWING HEAD AXLE ADJUSTMENT

Setting the sewing head axle alignment is necessary to insure a smooth rolling assembly. The axles will need to be adjusted if any side to side or front to back rocking motion is noticed when the machine is rolled on the frame. Additionally, a visual inspection of the sewing head wheel axle can pin point the axle that needs adjustment (See figure 9.2).

Figure 9.1: Sewing head and carriage assembly.

The two screws, found on the bottom side of the sewing head wheel axle, are used to adjust the assembly. You will need a ¼” hex key for the adjustment. Only loosen the screw closest to the wheel that is not touching the rail. As the screw is loosened, the axle will lower and bring the wheel into contact with the rail. Do not loosen the screw too much or the wheel on the opposite side may lift off of the rail. Check to insure that all of the play is removed from the assembly by moving the sewing head front to back and left to right. The sewing head should roll smoothly.

The adjustment is complete.
