1.1
Brief Description
The
550-12-23; -24
and
-12-26
are configured work stations for the
precrimping of upholstery pieces.
The work stations are equipped with a single-needle double locked
stitch machine with a differential drop feed (two independently-
adjustable feed dogs) and a differentiable, alternating top feed.
Via a keypad strip 15 different crimping values and 16 intermediate
values can be selected. A knee switch turns them on and off again. In
order to achieve a securer drawing of the stitches a second needle
thread tension is switched on when a crimping value is turned on. The
moment of switching on a second needle thread tension can be
preselected between crimping values 1 and 5 inclusive.
Drive and control of the work station occurs via a 3 phase motor in
conjunction with a Microcontrol control.
To increase the crimping intensity the work station is equipped with an
upper and /or lower tape feed and tensioning. The fixing tape width is
2,25 mm by the sub-classes 550-12-13; -12-14 and 3 mm by the
sub-class 550-12-16.
The tape tension can be turned on via a key and turned off through the
knee switch when the crimping value is switched off.

Proper Use
The
550-12-23; -24
and
-26
is a configured sewing station which can
be used for sewing light to medium heavy sewing material.
Such material is, as a rule, fabric composed of textile fibers or leather.
These sewing materials are used in the garment, furniture and car
upholstery industries.
Furthermore, it may be possible to also execute so-called technical
seams with this special sewing machine. Here, however, the operator
(DürkoppAdler AG would be applications are, on the one hand,
relatively rare and, on the other, their variety is immense. Depending
on the results of this evaluation it may be necessary to adopt
appropriate safety measures.
In general, only dry material may be worked with this special machine.
The material may not be thicker than 10 mm when it is pressed
together by the lowered unit could only be allowed to be operated with
eye protection. Such eye protection is not available at this time.
The seam is generally made with sewing yarns of textile fibers with
dimensions up to 15/3 NeB (cotton threads), 20/3 Nm (synthetic
threads) or 25/4 Nm (core spun threads). Those wishing to use other
threads must also first evaluate the dangers arising herefrom and, if
necassary, take safety measures.
This special sewing machine may only be ainstalled and operated in
dry and clean areas. If the sewing unit is employed in other areas,
which are not dry and clean, other, to be agreed upon, measures may
become necessary (see EN 60204-3-1: 1990).
We, as a manufacturer of industrial sewing machines, as that, at a
minimum, semi-skilled operating personel work on our products so that
all normal operations and, where applicable, their dangers can be
presumed to be known.
