2.3 Needle Plate

2.3.1 Lateral Position of the Needle Plate Carrier

6
During the sewing sequence the needle plate is always in the upper
position.
The needle hole mushroom is bevelled on the inside so that the trim, at
the beginning of the sewing procedure, cannot be pushed away and
builds no folds.
The functions " needle plate up " and " machine head down " are
triggered simultaniously. The function " needle plate down " occurs
only after the machine head has left its lower position and operated
the valve. With this function sequence, the cut-off end of the needle
thread is pulled out of the area of the needle plate before this has a
chance to clamp the thread.
