The class 869 is a sewing machine head 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 special 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, 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 machine
head. 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 eye-protection device is currently
available.
The seam is generally produced with textile-fibre sewing thread of
gauge up to 10/3 NeB (cotton), 10/3 Nm (synthetic) or 10/4 Nm
(covering yarn).
Before using any other thread the possible dangers arising must be
assessed and appropriate safety measures taken if necessary.
