Dürkopp Adler 887 is a special sewing machine for universal use.
•
It is a flatbed double-lockstitch machine.
•
The machine has a double intermittent feeding. A lower wheel
feeder and a driven roller presser feed in two steps, a needle feed
feeds in the first step only. The first step represents 50% of the total
stitch length.
•
Depending on subclass, the machine may be equipped with a large
or oversized hook, with automatic functions such as thread
trimming, automatic backtacking, automatic foot lifting.
•
Equipped with a two-piece vertical hook.
•
With a maximum of 12 mm 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.
•
The throat plate has replaceable inserts with the stitch hole
dimension difference, which are optional in dependence on the
needle number.

Automatic wick lubricating with an inspection glass on the arm for
machine and hook lubrication.

The 887 is a sewing machine designated for shoe, leather, and
upholstery sewing. The usual material is leather (natural or artificial).
It is possible to use it for shoe fabrics too. The equipment for light,
medium or heavy sewing is mounted on the machine as an option.
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 machine. The
material may be no thicker than 7 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.
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.
