An apparatus for severing and laying composite tape to form structural members with a shearing and compacting mechanism capable of a large variety of angular or circular severances. The severances are formed incrementally or digitally with a number of lengthwise slits of selected length. A plurality of transverse cuts are formed in the tape to intersect the slits to form a stairstepped severance. A curved chute at the discharge end of the apparatus has an endless belt to maintain the tape in alignment as it is pressed onto the work surface. The tape is compacted onto the work surface by a segmented roller system composed of several individual rollers. As the severance is reached, the rollers are selectively and individually disengaged from the work surface to correlate compaction termination with the shape of the severance.
In an apparatus for laying composite tape in parallel rows to form a structural member, the apparatus being of the type having a table, a tape laying head supported adjacent the table, drive means for providing relative movement between the head and the table, and a tape supply carried by the head, having a free end adapted to pass in a feed path in the head and out onto a work surface on the table, the improvement comprising:
