The class 550—767 machine is an engineered sewing station designed
for sewing light to medium-heavy material. Such material is generally
made of textile fibres, but it may also be leather. It is used in the
clothing industry and for domestic and motor-vehicle upholstery.
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 AG 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 sewing unit. The
material may be no thicker than 10 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.
The seam is generally produced with textile-fibre sewing thread of up
to gauge 11/3 NeB (cotton), 11/3 Nm (synthetic) or 11/4 Nm (covered
yarn). Before using any other thread the possible dangers arising must
be assessed and appropriate safety measures taken if necessary.
This sewing unit may be set up and operated only in dry,
well-maintained premises. If the sewing machine 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.
