Brief description

Die DÜRKOPP ADLER 579 is an automatic sewing machine designed
for sewing buttonholes in light to medium-heavy material.
Such material, which is generally made of textile or synthetic fibres, is
used in the clothing industry. 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 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 8 mm when compressed by the
lowered upper material clamps.
The material may not contain any hard objects. The machine may only
be operated with finger and eye protection. The seam is generally
produced with sewing threads of gauge up to 80/2 Nm (synthetic
threads with or without cotton covering). Before using any other thread
the possible dangers arising must be assessed and appropriate safety
measures taken if necessary. This machine may be set up and
operated only in dry, well-maintained premises. If it 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.
Depending on the subclass, the DÜRKOPP ADLER 579 is a
double-chainstitch buttonhole machine or a single-thread chainstitch
eyelet machine with CNC step motor for fabric feed and rotating
sewing mechanism.
As a buttonhole machine it works with two chainstitch loopers, the left
one carrying the thread, sewing buttonholes with or without an eye,
with taper, round or cross tacks.
As an eyelet machine it works with two chainstitch dummy loopers,
sewing single-thread eyelets.
The various subclasses of the 579 are fitted with different
thread-trimming systems.
Technical features
The machine is driven by a positioning drive built into the machine arm.
The movements of the X, Y and Z axles are driven by a step motor.
These drives are controlled by a DAC 2 electronic controller in
conjunction with various pneumatic machine functions.
The BF 2A operating panel is mounted in a visible location on the
machine arm and is thus easily accessible to the operator. This
drive-and-controller system has the following advantages:
Variable sewing speed depending on parameters such as the upper
–
thread, bobbin thread, material, seam width) up to a maximum of
2200 stitches/min.
Very quiet operation because there is no mechanical connection
–
and disconnection.
Additional noise reduction from the new needle-bar and looper
drive.
