ABSTRACT:
A method and apparatus for producing shipping rolls of wrinkle free ballistics type film faced composite sheet material which when assembled and cured on a shipping tube is subject to having surface wrinkles and creases. By assembling the material on a forming roll of large diameter, such that the thickness of the wound wraps of a given length of the sheet material is relatively thin, the deformation of each wrap is minimized during heat and compression curing and the cured material is free of surface wrinkles and creases. The cure-stabilized material then can be unwound and cut to desired length and wound on a small diameter shipping tube to provide a shipping package of material free of wrinkles and creases. The curing apparatus includes a cylinder with an internally lined inflatable bladder, such cylinder being adaptable to being moved into surrounding relation with the sheet material. The forming roll is arranged to supply heat from the interior of the assembled wraps of material while the surrounding inflated bladder exerts pressure to cure the material over a predetermined cure cycle.
