Clamps And Table Plate; Position Of Table Plate With Respect To The Needle - Duerkopp Adler 506-3 Service Instructions Manual

7. Clamps and table plate

7.1 Position of table plate with respect to the needle

The transmission of the movement from the disc cam to the clamps
and the table plate is effected by lever systems.
Within certain limits seam-type sizes can be altered by changing the
lever transmission ratios.
The size of the safety gap between the table plate 1 and the needle is
determined by the extent of the transverse and longitudinal movement
of the table plate.
For safety reasons the edges of the hole in the table plate 1 must be at
a constant minimum distance from the needle when it penetrates the
material.
CAUTION: Danger of breakage
If this safety distance is not observed, the needle will strike the table
plate 1.

CAUTION: danger of injury
