Claim 16:
17. A stretching system comprising a plurality of tenter-clip carriages that are constructed according to claim 1, comprising the following features:
two circumferential guide tracks that are arranged with a lateral offset transversely to an extraction direction of a material web to be stretched;
a circumferential conveyor system having a plurality of tenter-clip conveyor units is arranged along each of the two guide tracks, with which circumferential conveyor system a material web to be stretched can be grasped from the side and passed through the stretching system from an inlet zone to an outlet zone;
the tenter-clip conveyor units each comprise a tenter-clip carriage;
the circumferential guide track comprises a guide rail arrangement along which the tenter-clip carriages are movable in a supported manner by means of rollers or sliding elements, or a weighted roller or a weighted sliding element, or a securing roller or a securing sliding element, or at least one stabilising roller or at least one stabilising sliding element;
the guide rail arrangement comprises at least one upwardly facing load-bearing rail surface and a rolling and/or sliding surface on the side remote from the material web and a rolling and/or sliding surface aligned on the material web-side;
rollers and/or sliding elements are rigidly mounted and/or held on the rolling and/or sliding surface aligned on the side remote from the material web, which rollers and/or sliding elements roll or slide on the rolling and/or sliding surface aligned on the side remote from the material web;
the at least one stabilising roller or at least one stabilising sliding element is provided on the rolling and/or sliding surface aligned on the side, which stabilising roller or stabilising sliding element is in contact with the rolling and/or sliding surface aligned on the material web side,
the at least one stabilising roller or the at least one stabilising sliding element can be adjusted perpendicularly or transversely to the guide rail arrangement and thus perpendicularly or transversely to the rolling and/or sliding surface (7d) aligned on the material web side.
