1. Product Description

The DÜRKOPP ADLER 869 is a single-needle double lockstitch free-arm sewing machine with a lower feed, a needle feed and an alternating foot-upper feed. Depending on the subclass it comes as single or double needle machine, with or without electropneumatic driven thread trimmer.

The machines are equipped with a large horizontal hook.

With a maximum of 20 mm fabric clearance when sewing feet are

lifted.

The residual thread length after thread trimming is about 15 mm.

A safety clutch prevents a changing of the hook setting or a hook

damage in the case of a thread deflection into the shuttle track.

Automatic wick lubricating with an inspection glass on the arm for

machine and hook lubrication.

All Subclasses, excluding those classes without thread trimmer

device, are equipped with a keypad (6 keys). An additional key, within reach of the seamstress, can optionally also be assigned one of the six different functions.

Integrated bobbin winder

2. Designated use

The class 869 is a sewing machine head designed for sewing light to medium-heavy material. Such material is generally made of textile fibres, but it may also be leather. It is used in the clothing industry and for domestic and motor-vehicle upholstery.

This special 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, 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 sewing machine head. The material may be no thicker than 10 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 eye-protection device is currently available.

The seam is generally produced with textile-fibre sewing thread of gauge up to 10/3 N eB (cotton), 10/3 Nm (synthetic) or 10/4 Nm (covering yarn). Before using any other thread the possible dangers arising must be assessed and appropriate safety measures taken if necessary.

3. Subclasses

This special sewing machine may be set up and operated only in dry, well-maintained premises. If the sewing machine is used in 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.
