1. A tenter-clip carriage for a stretching system, comprising the following features:
the tenter-clip carriage has a longitudinal direction and a transverse direction,
a. wherein the longitudinal direction runs between a leading side and a trailing side opposite thereto; and
b. wherein the transverse direction runs transversely or perpendicularly to the longitudinal direction between a clamping side for a material web to be stretched and a guide rail side opposite thereto;
the tenter-clip carriage comprises a clip body, wherein the clip body has a clamping device via which a material web edge of a material web to be stretched can be clamped;
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 and/or connected to 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, and
the at least one stabilising roller or the at least one stabilising sliding element can be adjusted perpendicularly or transversely to the longitudinal direction;
for the at least one stabilising roller or the at least one stabilising sliding element, a force accumulator or spring-force accumulator is provided via which the at least one stabilising roller or the at least one stabilising sliding element is held forcibly in a yieldable manner and/or held in a pretensioned manner with a predeterminable or presentable force away from the clamping side in the direction of the guide rail side opposite the tenter-clip carriage and/or opposite the partial chain portion of the conveyor chain arrangement.
