ABSTRACT:
The two halves of a split annular inflatable brake are formed by laying up a number of flat rubber body plies and interleaved end patches which extend longitudinally beyond the ends of the body plies. The sides of the body plies, some of which are fabric reinforced, are successively folded over each other and stitched to form a multi-layered flattened tubular body. The end patches are folded in turn over the ends of the flattened tubular body, and in the case of fabric reinforced patches, are pinched and trimmed along the side edges of the flattened tubular body. Unreinforced end patches are cut inward from the sides to form a center flap which is folded down against the sides of the flattened tubular body and side flaps, one of which is removed, and the other of which is pulled circumferentially around the tubular body over the folded center flap. The split air brake is built up on an arcuate mold half and then the remaining mold parts are assembled around the built up part for curing.
