Designated use
The 69 is a special sewing machine designed to be used to sew light to medium-heavy
materials. As a rule such material consists of textile or synthetic fibres, but it also
includes leather.
These materials are used in the clothing, footwear and leatherwear industries, as well
as in domestic and automobile upholstery.
This special sewing machine can also be used to execute so-called technical seams.
However, the operator must carry out an assessment of the possible dangers (with
which DÜRKOPP ADLER AG would be happy to assist), as such applications are
comparatively unusual and they are potentially of enormous diversity. Depending on the
outcome of this assessment it may be necessary to take special safety precautions.
Generally speaking material processed with this special sewing machine must be dry,
its thickness when compressed by the lowered sewing feet must not exceed 7 mm and
it must contain no hard objects, since otherwise the operator of the machine would have
to wear protective goggles (which cannot at present be supplied).
The seam is generally executed with textile-fibre sewing threads up to 30/3 NeB (cotton
yarns), 40/3 Nm (synthetic yarns) or 30/3 Nm (covering yarns) in size. The use of any
other threads must also be subject to an assessment of the risks involved and the
taking of any necessary safety precautions.
The premises in which this special sewing machine is set up and operated must be dry
and well-maintained. If it is to be used in premises which are not dry and
well-maintained, special precautions may be necessary: these must be the subject of
an agreement (see EN 60204-3-1:1990).
As manufacturers of industrial sewing machines we work on the assumption that
personnel working on our machines will be at least semi-skilled, so that they can be
presumed to be familiar with all normal operations and with the dangers inherent in
them.
