A side wall of the housing is designed as a separate component holding the bearing spindles for the figure rollers and the transmission elements. The side wall holding the bearing spindles is constructed as an extruded or stamped part and consists of one piece with the spindles. The side wall and the bearing spindles are made of plastics. The side wall has mounting elements enabling it to be plugged onto the housing. Pushbuttons at the four corners can be used to secure the side wall on the housing. Stops for a catch and an armature are injected onto the housing.
