Abstract: The present invention is directed to a pneumatically actuated redirection surface guide tool for use in tape laying systems. In the laying of unidirectional, pre-impregnated carbon fiber tapes, for instance, a tape can be directed between a tape supply reel and a tape laying head through use of one or more of the disclosed guide tools. The surface of the guide tool includes small holes that allow for positive and negative air pressure to be applied to the surface to increase or decrease the friction between the tape that is passing over and being redirected by the surface.

Abstract: An automated tape head assembly for a multiple axis tape laying machine includes a tape supply reel and a tape compaction roller, and a chute. Tape passes from the supply reel, through the chute, to the tape compaction roller. The tape path and at least a portion of the chute are maintained substantially at a zero Gaussian curvature. The tape path and chute are curved to define a compliance loop that results from a substantially or partially unrestrained curved path between the supply reel and the compaction roller. This structure allows the compaction roller to shift laterally and vertically with respect to the supply reel while the supply reel is in a fixed position with respect to the tape head assembly generally. This structure also allows the compaction roller to roll, steer, and follow the fiber tape's natural path, all with significant independence from the supply reel.

Abstract: A method and apparatus provide for continuous automatic cutting of a web of material wherein the web has a web anomaly that prevents the web from lying flat and straight. The web anomalies include when a web has a non-zero Gaussian curvature and/or when the web or roll of material follows an arc when the roll is unrolled onto a flat surface. These web anomalies may be justified through use of computer controlled cutters that correct the motion trajectory of the cutter relative to the web and also by means of distortions to the support surface upon which the cutting of the web is to occur.
