MOLDING MANUFACTURE OF EXTERNAL LEATHER BAG FOR HEADREST FOR AUTOMOBILE

PURPOSE:To manufacture the skin having a pattern of a headrest body by placing a synthetic resin sheet heated onto both molds, pushing the synthetic resin sheet against a recessed section having a pattern by negative pressure from the mold side and compressed air from the upper side of the synthetic resin sheet and transferring the pattern of the recessed section to the synthetic resin sheet. CONSTITUTION:An arbitrary number of pinholes 5a, 5b formed to the recessed sections 4a, 4b of molds 3a, 3b are introduced to a negative pressure source, synthetic resin sheets 1a, 1b are sucked to the recessed sections 4a, 4b with patterns while compressed air is injected into covers 11 for compressed air, the synthetic resin sheets 1a, 1b are contact-bonded with the recessed sections 4a, 4b with the patterns, and the patterns of the recessed sections 4a, 4b are transferred to the synthetic resin sheets 1a, 1b. The covers 11 for compressed air and holding frames 2a, 2b are removed, intermediate heaters 16 are inserted, and the molten positions of the synthetic resin sheets 1a, 1b are heated. A frame 15 is fitted to a main mold (under the state in which negative pressure is kept) 1a, and the main and sub molds 3a, 3b are pressure-welded. The upper and lower synthetic resin sheets 1a, 1b are heat-fused to a collar form along the external shape of a headrest body 12 and the external shape of a window hole 17, and the outsides are cut.
