Abstract
An elongated and cross-section polygonal work piece carrier (1) has at least two clamping surfaces (2) extending parallel to its longitudinal axis (3). It is retained in bearing (5, 9) at least at one end, to be rotatable about its longitudinal axis over 360.degree.. Each of the clamping surfaces (2) is supplied with at least two rotatable work piece holding tables (11) located in a row adjacent each other. The holding tables (11) are coupled by gears (25, 26, 33) with each other and with a common drive gear (35) in such a manner that all tables, in dependence on the rotation of the work piece carrier (1) about its longitudinal axis (3), will rotate over its respective rotation axis (12) about a predetermined angle, depending on the angle of rotation of the work piece carrier; an interrogation device is provided to interrogate whether all rotated tables are in predetermined, locked angular positions.
