摘要： 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.-

摘要： The invention relates to a ventilation module for a film stretching system at least one first outlet nozzle arrangement having an outlet nozzle, wherein the at least one outlet nozzle extends with its longitudinal direction transverse or perpendicular to the withdrawal direction of a plastic film web and is oriented in parallel to the transport plane. A first return system is provided with at least two extraction channels, each having an intake region. The at least two intake regions are spaced apart from one another in the withdrawal direction and oriented in parallel to the transport plane. The at least one outlet nozzle of the at least one first outlet nozzle arrangement is arranged between the first and the second intake region. The at least two intake regions are arranged exclusively before and/or after the at least one first outlet nozzle arrangement in the withdrawal direction of the plastic film web.

摘要： A film winding system (1) for a film stretching unit (110) comprises a film entry area (3) through which a film web (2) to be wound can be fed to the film winding system (1). A first winding station (4) is configured in a winding position to wind the film web (2) into a film bale (5). A contact roller (6) and a measuring roller (8) are provided, the contact roller (6) being arranged adjacent to the first winding station (4) in the winding position and being configured to guide the film web (2) to the first winding station (4). The measuring roller (8) is arranged before the contact roller (6) in the movement direction of the film web (2) and is configured to guide the film web (2) to the contact roller (6). A first adjustment device (10) is provided and configured to move the measuring roller (8) relative to the contact roller (6) along a travel path in such a way that a degree of wrapping over which the film web (2) covers the contact roller (6) can be varied.

摘要： An improved stretching system has the possibility of reducing the distance between two successive guide clips, for example. In technical terms, this is solved by using control clips. For example, a control clip can be provided between two successive guide clips and causes the distance between two successive guide clips to be altered by way of a lateral position adjustment by means of a control rail.
