ABSTRACT:
An index plate (9) is moiunted on a shaft (7) which is supported against axial displacement on a machine frame (1) and is stepwise rotatably drivable, said plate carrying clamping devices (10) arranged around the shaft and each intended for one workpiece (11). On either side of the indexing plate (9) a unit carrier (20) is arranged axially displaceably of the unit carriers (20) towards the indexing plate (9) into a stop position and for displacement of the unit carriers (20) away from the indexing plate a displacement drive (31) is associated with each of said carriers. The two unit carriers (20) are guided solely on the shaft (7) and are supported on the machine frame (1) only against rotation. Each of the unit carriers (20) comprises a crown wheel type serration or toothing (29) which faces the indexing plate (9) and which in the stop position of the respective unit carrier is in torque-transmitting engagement with a crown wheel type serration (28) formed on the indexing plate (9) and defining the stop position. Arranged on each of the unit carriers (20) are a plurality of working units (45). For executing feed movements the working units (45) are guided displaceably on the associated unit carriers (20) and each connected to a feed unit (53) activatable in the stop position thereof.
