3.7.4 Knife drive
The blade shaft with the knife is moved in an oscillating
pattern by a motor using a mechanical gear unit. An
eccentric disc fitted frictionally onto the motor shaft is
guided in an axial bearing block with a slotted hole that is
connected to the blade shaft and thus converts the
rotational motion into a translatory motion.
The inclination or the distance of the knife to the kneading
roller and thus the cut-off thickness of the cookies can be
adjusted by a cam drive with a rotary wheel, the knife
setting.
