摘要: In an improved process for processing a film web, the film web is cut in the longitudinal direction, forming a marginal strip and a remaining film web with a width reduced by the width of the marginal strip. The marginal strip is transferred to a movable film-drafting device on which is arranged a gripper. The remaining film web is separated entirely or partially by cutting and also possibly by tearing. The film-drafting device is moved along one side of a roller arrangement, threading the film web into the roller arrangement. The film-drafting device is moved along one side of a winding device comprising at least one winding roller up to a release or end position. The film-drafting device is opened at the end position to release the marginal strip.

摘要: Conventional clips must be manufactured with high precision and run the risk of becoming stiff in the course of time or even to become inoperative in extreme cases due to sediments in their pivoting mechanism. In order to obtain a clip which remains operational in spite of sediments and the danger of clogging and which is furthermore easy to assemble and disassemble, the clip lever is supported with a first bearing part on another bearing part on the side of the clip body, forming a kind of rocking bearing. The rocking bearing can in particular be composed of a knife-edge or rolling bearing. This clip is particularly useful for plastics stretching machines.
