1. Description of product

1.1 Description of proper use

The 1280/5 is an engineered sewing station which can properly be used for sewing light to medium-weight material. Such material is, as a rule, made of textile fibres. These materials are used in the garment industry.

In general only dry material must be sewn on this machine. The material must not contain any hard objects.

The seam is generally made with core thread, polyester fibre or cotton threads.

The dimensions for needle and hook threads can be taken from the table in chapter 4.2.

Before using any other threads it is necessary to estimate the consequential dangers and to take the respective safety measures, if required.

This sewing unit must only be installed and operated in dry and well-kept rooms. If the sewing unit is used in other rooms, which are not dry and well-kept, further measures to be agreed upon may become necessary (see EN 60204-31 : 1999).

We, as a manufacturer of industrial sewing machines, assume that at least semi-skilled operating personnel will be working on our products so that all usual operations and, where applicable, their risks are presumed to be known.

1.2 Brief description

The Beisler 1280/5 is an engineered sewing station for closing long seams, as e.g.

® trousers side seams and crotch seams,

® side seams without vent in upper fabric,

® lining in skirt parts

According to the machine head it is possible to sew

® double-chainstitch seams (401),

4-thread safety seams (515) or 5-thread safety seams (516).

The engineered sewing station is mainly used for sportswear trousers, as e.g. cotton trousers, Chinos and US style trousers.

All sewing station components are mounted on a stand welded of square steel tubes and controlled by a microprocessor system.

The sewing station is operated via a control panel. Here it is possible to call up various control programs, to define new programs and to check all inlets and outlets for maintenance and repair purposes.

4. Operation of the sewing machine head

4.1 General notes

The operation of the sewing machine head (needle insertion, threading of needle thread and hook thread etc.) is described in the attached separate Pegasus operating instructions.

The instruction manual is included in the accessories of the sewing unit.

Attention: Risk of injury!

Please read the operating instructions of the sewing machine head carefully and observe all notes on safety.

4.2 Recommended threads

Needle system:

Recommended needle size:

B27

Nm 80 for very thin material

Nm 90 for thin material

Nm 100 for medium-weight material

Nm 110 for heavy-weight material

High sewing security and good sewability are achieved with the following core threads:

–

Two-ply polyester endless polyester core-spun

(e.g. Epic Poly-Poly, Rasant x, Saba C, ...)

–

Two-ply polyester endless cotton core-spun

(e.g. Frikka, Koban, Rasant, ...)

If these threads are not available, the polyester fibre or cotton threads listed in the table can also be sewn.

Often two-ply core threads are offered by the thread manufacturers with the same designation as three-ply polyester fibre threads

(3cyl.-spun).This causes uncertainty with regard to twisting and thread thickness.

When in doubt, unravel the thread and check whether it is twisted 2- or

3-ply.

The label no. 120 on the thread reel of a core thread corresponds e.g.

to the thread size Nm 80/2 (see table values in brackets).

In case of monofilament threads you can use needle threads and hook threads of the same thickness. The best results are achieved with soft and elastic threads (software) of the thread thickness 130 Denier.
