Abstract: Tape (100) being laid by a tape laying machine (2) is transported by a continuous strip of backing paper (102). A rotary cutter (12) is mounted on one arm (36) of a C-shaped frame (34). An anvil (20) is mounted on the other arm (38). Frame (34) moves laterally to move cutter (12) and anvil (20) laterally across tape (100) with tape (100) and paper (102) therebetween. A single point on anvil (20) supports the portion of tape (100) being cut throughout the length of the cut. Therefore, an essentially constant distance between cutter (12) and anvil (20) is maintained to completely sever tape (100) without severing paper (102).
