A tenter-clip carriage for a stretching system comprises a longitudinal direction (LR) and a transverse direction and a clip body having a clamping device. The tenter-clip carriage comprises fastening portions in order to fasten the tenter-clip carriage to a partial chain portion of a conveyor chain arrangement of the stretching system. The tenter-clip carriage comprises at least one stabilising roller or at least one stabilising sliding element. The at least one stabilising roller or the at least one stabilising sliding element is, by means of a guide device: a) held directly on the tenter-clip carriage; or b) held indirectly on the tenter-clip carriage via a pin that connects two chain segments of the partial chain portion of the conveyor chain arrangement to one another and, specifically, unaffected by the feed and drive forces acting on the tenter-clip carriage or the partial chain portion to move the tenter-clip carriage and/or the partial chain portion.

The at least one stabilising roller or the at least one stabilising sliding element can be adjusted perpendicularly or transversely to the longitudinal direction by a force accumulator or spring-force accumulator.

The invention relates to an improved transport system, in particular for a stretching system, characterized amongst other things, by the following characteristics: a support rail and/or a guide rail, over which a conveyor chain with clip chain units can be displaced, are provided, said units subdividing into a clip part and a chain part, said support rail or the guide rail or the support rail and the guide rail is/are provided with a channel which transverses in the longitudinal direction at least in one of the partial lengths of the support rail and the guide rail. The support rail running surface comprises a plurality of outlet openings through which the compressed air can be guided on the channel for generating an airbag between the support rail running surface and an air bearing cushion plate on the clip-chain unit and/or the running rail running surfaces comprise a plurality of outlet openings through which the compressed air can be guided on the channel by generating an air bag between the respective guide rail running surfaces and a bearing device on the clip chain unit.
