Fig. 4
On the Kl.VEB200-1 both cloth retainers are feathered.
The pressure of about 4N left and 4N right is set by the bushes (5) (Fig. 2).
On the Kl.VEB200-2 both cloth retainers are feathered and combined with a
setting screw (4) (Fig. 2) that limits the cloth retainer lift to the top.
Basic setting for the pressure of the two cloth retainers about 4N. When setting
the cloth retainer lift, the pressure changes.
This combination is called plunger stopper, but can be used only in combination
with feathered plungers.
Plunger stopper and feathered plunger prevent that outer seams of the sewing
material are punctured during the sewing across cross-seams and other
thickenings and undesired markings become visible.
