ABSTRACT:
A conveyer (10) is provided for the transport of workpiece carriers (12) to be received by a positioning and holding member (15) for processing of the workpieces arranged on the carriers. A stopper member (30) is arranged behind the positioning and holding member (15) as seen in transport direction. A leading workpiece carrier (I) is stopped by the stopper member (30) in such a manner that a following workpiece carrier (II) is brought to a standstill exactly in the receiving position of the positioning and holding member (15). This allows exact positioning and separation of the workpiece carriers without the need of highly precise control of a separating member. A leading workpiece carrier (I) will remain in its position at the stopper (34) until having stopped a following workpiece carrier (II) in the positioning and holding member (15).
