2. Description of proper use
Class 510 is an automatic bartacker determined for processing light to
medium-weight material, i.e. fabrics made of textile fibres or leather.
Such sewing materials are used in the clothing industry and for the
production of home and car upholstery.
Furthermore, this automatic bartacker can also sew so-called technical
seams. However, in this case the user has to estimate the possible
risks (preferably in cooperation with DÜRKOPP ADLER AG) because
on the one hand such fields of application are comparatively rare and
on the other hand there is an immense variety of possibilities.
According to the result of this estimation suitable safety measures may
have to be taken.
Generally only dry fabrics must be processed on this automatic
bartacker. The material must not be thicker than 10 mm when
compressed by the lowered sewing feet. It must not include any hard
objects as otherwise the operator would have to wear an eye
protection when working with the automate. Such an eye protection
cannot be delivered at present.
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 510-211/212 threads of the dimension 50/3 - 120/3
Class 510-213 threads of the dimension 30/3 - 120/3
If other threads are to be used, it is indispensable also in this case to
consider the possible risks and to take corresponding safety
measures, if necessary.
This automatic bartacker must only be installed and operated in dry
and well-kept rooms. In case it is operated in other rooms which are
not dry and well-kept further measures can become necessary which
have to be agreed upon (see EN 60204-31: 1999).
We as manufacturers of industrial sewing machines take it for granted
that at least semi-skilled operators are working with our products so
that we can assume that all usual operations and their risks are known
to them.
