1. Product description

The DÜRKOPP ADLER 275 is a special sewing machine with universal applications.

Basic type

Single-needle double-lockstitch machine with underfeed, differentiable-foot overfeed

and thread cutter for light to medium-heavy material with 4-mm stitch length and max.

8-mm overfeed length.

2. Designated use

The 275 is a special sewing machine designed to sew light material. Such material is

generally made of textile fibers, but it may also be leather. It is used in the clothing and

domestic-upholstery industries.

This sewing machine can also be used to produce so-called technical seams. In this

case, however, the operator must assess the possible dangers which may arise (with

which DÜRKOPP ADLER AG would be happy to assist), since such applications are on

the one hand relatively unusual and, on the other, they are so varied that no single set

of criteria can cover them all. The outcome of this assessment may require appropriate

safety measures to be taken.

Generally only dry material may be sewn with this machine. The material may be no

thicker than 6 mm when compressed by the lowered sewing feet. The material may not

contain any hard objects, since if it does the machine may not be operated without an

eye-protection device. No such device is currently available.

The seam is generally produced with textile-fibre sewing thread of gauge up to 30/2 Nm

(synthetic yarn) or 30/3 Nm (covering yarn). Before using any other thread the possible

dangers arising must be assessed and appropriate safety measures taken if necessary.

This special sewing machine may be set up and operated only in dry, well-maintained

premises. If the sewing machine is used in other premises which are not dry and

well-maintained it may be necessary to take further precautions (which should be

agreed in advance - see EN 60204-31: 1999).

As manufacturers of industrial sewing machines we proceed on the assumption that

personnel who work on our products will have received training at least sufficient to

acquaint them with all normal operations and with any hazards which these may involve.
