Product Description; Designated Use - Duerkopp Adler 467 Operating Instructions Manual

1. Product description

The DÜRKOPP ADLER 467 is a special sewing machine with a comprehensive range
of applications.
Flat-bed double lockstitch sewing machine with underfeed, needle feed and
alternating-foot overfeed.
Sub-classes available with or without thread cutter beneath the needle plate.
Thread control with one main tensioner.
Maximum clearance beneath lifted sewing feet 16 mm.
Stroke of alternating sewing feet with the sewing machine at a halt adjustable
between 1.5 and 6 mm by press-button and handwheel (adjusting cam).
Three oil-filling points for manual lubrication of sewing head and shuttle bearing.
Large, two-part vertical shuttle (to the right of the needle) with bobbin-housing lift.
A safety coupling prevents the shuttle from disturbance or damage if thread gets
into the shuttle track, blocking the shuttle.

2. Designated use

The 467 is a special sewing machine designed for use with light to medium-heavy
materials. As a rule such materials are fabrics consisting of textile fibres, but they also
include leather. They are used in the clothing, domestic-upholstery and
automobile-upholstery industries.
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 10 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 of dimensions up to
11/3 NeB (cotton thread), 11/3 Nm (synthetic thread) or 11/4 Nm (covering yarn). 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.
