4.7.1 Setting the plunger limit stop for sewing over cross seams
The cloth retainer stroke is set by means of a knurled nut (2) Fig. 6a, which serves as
upper limit stop. To set the stroke place the material (a normal fabric layer without
cross seam). Close the cloth support arm and turn the hand wheel manually until the
needle penetrates the fabric. In this position there should be nearly no space between
cloth retainer and fabric layer. If the setting is correct the automatic plunger should be
compensating the over cross seams, so that the needle does not penetrate the outer
layer.
The pressure of the cloth retainer on the fabric layers or the hem edge can be adjusted
through turning the knurled nut (1) Fig. 6a and Fig. 6b. The pressure should be as low
as possible to avoid twist or marks resulting from the pressure between plunger and
cloth retainer, mainly when sewing delicate fabrics as e.g. velvet. However, the
pressure should be high enough to keep the material between plunger and cloth
retainer during the time of needle penetration.
The setting of the plunger limit stop has a considerable influence on the stitch quality.
4.7.2 Setting the automatic plunger
The spring pressure of the automatic plunger is set at works and usually needs not to
be altered. If the plunger limit stop is set correctly over cross seams the needle should
not penetrate the outer fabric layers.
For plunger settings please refer to the mechanic's instructions.
4.7.3 Setting the cloth retainer Cl. VEB100-4
The Cl. VEB100-4 is equipped with an additional cloth retainer made of a spring plate
(1), Fig. 6b, that holds the sewing material firm on the one-sided bevelled plunger (2)
with the roll seam nozzle (3) for the piercing of the needle (Fig. 6b).
The pressure of the cloth retainer on the sewing material is specified by the shape of
the cloth retainer plate.
The cloth retainer is screwed fast to the stitch plate and needs to be set so that the
sewing material cannot be shifted while the needle pierces.
The correct setting has a significant influence on the quality of the stitch.
For correct setting of the seamer, refer to point “5.6.2 Sewing with folder".
