Product Description

The

Dürkopp Adler 550-16-26 is a configured sewing station for the

sewing-on of sleeves.
The workstations are equipped with a single needle, double lockstitch,

post-bed machine with bottom and top belt feed.
30 different fullness values can be selected via the keypad. In order to

achieve a firmer pulling-on of the stitch, a supplementary tension can

be added when a high fullness value is turned on.
Further details:

Step motor technology for top and bottom belt feed.

Material-protective belt feed with two individually powered belts for

the top and bottom feed.

Proper Use

The 550-16 is a sewing place which can properly be used for sewing

litght to medium weight material. Such material is, as a rule, material

made up of textile fibres. This material is used in the garment industry.
Further, it may be possible to also conduct so-called technical seams

with this special sewing machine. Here, however, it is essential that the

operator (

Dürkopp Adler AG would be pleased to collaborate) make

an evaluation of the possible dangers because such applications are,

on the one hand, comparatively rare and, on the other, the variety is

immense. Dependent of the result of this evaluation, appropriate safety

measures are to be taken.
Generally, only dry material should be sewn on this machine. The

material should not exceed the thickness of 7 mm when compressed

by the lowered sewing foot. The material should not contain any hard

objects, otherwise it would be necessary to protect the eyes during the

sewing process. For the time being, no such guard is available.
The seams are produced generally with threads of textile fibres of a

dimension up to 70/3 - 140/3 NeB. Before using any other threads it is

necessary, also in this case, to estimate the consequential dangers

and to take, if necessary, the respective safety measures.
This special sewing machine may only be installed and operated in a

dry and clean environment. If the sewing machine is used in another

environment which is not dry and clean, further measures, which are to

be agreed upon, may be necessary (see EN 60204-31:1999).
We, as a manufacturer of industrial sewing machines, assume that at

least semi-skilled operating personnel will be working on our products

so that all normal operations and, where applicable, their dangers are

presumed to be known.
