2110683 9221595 PCTABS00017 The invention relates to a transfer unit for transferring objects from a starting position to a final position, preferably between two presses in a plate pressing line. The transfer unit comprises two carriages (4, 5) which are displaceable along supporting rails (2, 3) and are provided with rotatable gripping devices (9-12) to grip and hold the object during the transfer which can be effected with or without turning over at the same time. The turn-over device makes it possible to turn the object during transfer and comprises a turning arm (24), one end of which is mounted in the carriage (4, 5), and the other end of which supports a follower (25) for cooperation with a guide rail (26, 27) with an essentially V-shaped portion (32-34), along which the turning arm (24) is guided as it is pivoted. According to the invention, the essentially V-shaped portion (32-34) consists of two arcuate guide rail sections (32, 33), which each extend from an individual straight portion (28, 29) of the guide rail, the free ends of said arcuate sections being equidistant from a point (35) where the tangents from the free ends intersect, and a switch piece (34) which can be pivoted between two end positions, in which it forms a continuation of one or the other of the two arcuate guide rail sections (32 or 33). The switch piece (34) can be locked in each of the end positions by means of blocking means (42) which can be released as the follower (25) is inserted into the switch piece (34).
