The invention relates to a tenter chain-conveyor for tenter clips with roller bearing, in particular for film stretching machines. The running rollers and supporting rollers arranged on the tenter clips are accommodated by an upright, continuous and flexible guide rail. In this arrangement the vertical guide rails standing on their narrow side are formed by an assembly of spring strips. The arrangement is conceived such that the upwardly facing narrow side of the guide rail has two bevels opposite one another such that a roof-like shape is produced. The lower narrow side of the guide rail is correspondingly provided with two bevels. For each of the four inclined running surfaces on the guide rail, in each case a running roller with a correspondingly inclined rotation spindle is provided in the clip. The rollers fulfil two functions in each case and act both as running roller for absorption of the horizontal forces and also as supporting roller for absorption of the vertical forces.
