2. Proper and Intended Use
The class 511 machine is a bartacking machine designed for sewing
light to medium-heavy material. Such material is generally made of
textile fibres, but it may also be leather. Such fabrics are used in the
clothing industry and for domestic and motor-vehicle upholstery.
Furthermore, this automatic bartacker can also sew “technical” seams.
In such a case, the operator must assess the possible dangers which
may arise (preferably in conjunction with DÜRKOPP ADLER AG). Such
applications are relatively unusual and also so varied that no single set
of criteria can cover them all. You may need to take appropriate safety
measures based on the outcome of this assessment.
Generally, only dry fabrics can be processed on this automatic
bartacker. The material may be no thicker than 10 mm when
compressed by the lowered sewing feet. The material should not
contain any hard objects. If hard objects are present, the machine must
be operated with protective eye wear. We currently do not provide such
eye protection.
In general the seam is produced with sewing threads made of textile
fibres (cotton threads, synthetic threads or core threads) with the
following dimensions:
Class 511-211/212 threads of the dimension 50/3 - 120/3
Class 511-213/214 threads of the dimension 30/3 - 120/3
If other threads are to be used, it is important to consider the possible
risks and to take corresponding safety measures.
This automatic bartacker must only be installed and operated in dry
and well-kept rooms. If it is operated in other spaces which are not dry
and well-kept, further measures may need to be agreed upon (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.
