ABSTRACT:
A transport apparatus for use in a mass production is provided, which includes a first transport belt for transporting objects at either regular or irregular intervals and for discharging such objects at a zone of transfer. A second transport belt is included for receiving the objects at the zone of transfer from the first transport belt and for discharging the objects with equal spacings between such objects. An endlessly revolving articulated link chain, having chain links connected to one another by articulated links, has drivers mounted on every second articulated link. A first guide rail has a guide edge for displaceably guiding the articulated links upon which said drivers are mounted, while a second guide rail extends in a line deviating from the course of the first guide rail so that a spacing between the first guide rail and the second guide rail increases within the zone of transfer for temporarily reducing the spacing between the drivers. Arms arranged on the articulated links of the link chain, with the articulated links supporting the arms being disposed between the articulated links upon which the drivers are mounted. A guide body is mounted on each of the arms, with each of the guide bodies being guided by the second guide rail. The arms permit a substantially torsion-free deflection of the chain links within the zone of transfer.
