1. Product description

The DÜRKOPP ADLER 577-1111 is an automatic double lockstitch

machine with bottom and top feed for sewing buttonholes with two

straight bars.

Normal sewing mode:

During the sewing process the fabric face ( the face seen) ) is up.

The machine can be supplied in three installation variants ( see on the

left ).

2. Normal use

The automatic sewing machine DÜRKOPP ADLER 577-1111 has been

designed for sewing light to middle-heavy weight material, as used in

the apparel industry.

Such material consists generally of textile or synthetic fibres.

Furthermore, the machine lends itself for producing so-called technical

seams. In this case, the user must estimate any possible dangers

(contact dürkopp adler ag for help), Technical seams are seldom, but

they may be very versatile. Proper safety precautions, depending on

the result of such an estimation, must be taken. Generally, only dry

material should be sewn on this machine. And the material should not

exceeded the thickness of

4 mm when compressed by the lowered sewing foot.

The material should not contain any hard objects, because otherwise it

would be necessary to protect the eyes during the sewing process..

For the time being, no such eye guard is available. The seams are

produced generally with threads up to 65/2 Nm ( cotton-covered

synthetic threads or synthetic threads ) Before using any other threads

it is necessary, also in this case, to estimate the consequential

dangers and to take, if necessary, the respective safety measures.

This automatic sewing unit should be installed and operated only in

dry and proper rooms. Otherwise, further precautions (to convene)

may be needed, ( siehe EN 60204-3-1:1990 ). We.manufacturers of

industrial sewing machines, assume, that our machines will be

operated at least by a well trained staff, knowing all usual controls and

any possible dangers.
