single layer is then cut into lengths equal to the intended width of three layer prepreg tape 30 these pieces are stacked in a sheet feeder so they can be fed into the following process with their reinforcing filaments not aligned with the 0 degree filaments of the outer layers in this example the filaments would be at 90 degrees to the outer layer filaments the 90 degree sheets are fed into the prepreging process in such a way that there are no gaps or overlaps where adjacent sheets meet after the three layer prepreg is finished it is difficult to see the 90 degree sheets meet each other during the next step the process is not conventional since two webs of unidirectional prepreg are used simultaneously in the process and the 90 degree sheets are also fed into the region between them the two wet webs converge at the entrance of a vertically oriented drier and fusing oven the 90 degree transverse filament sheets in this example are fed into the merge point of the two wet unidirectional webs surface tensions of the two wet webs hold the transverse filament sheets in place as they move upward through the drier both wet webs are dried in the drying oven the layer with transverse filaments does not require drying the three layers are then passed through the fusing oven in which all three are heated so the resins.
