The press-type apparatus for thermally bonding thermoplastic sheet material workpieces (66, 68) is provided with a pair of opposed platen assemblies (14, 16) which each include an inflatable set (32, 34) of compliant diaphragm members (40, 42), a pair of opposed heat sources (26, 28) which may be brought into and retracted from contact with the diaphragm members (40, 42), and a source of pressurized fluid for inflating the diaphragm sets (32, 34) and for cooling the heated workpieces (26, 28). The method for operating the press-type apparatus basically involves both heating and cooling the assembled workpieces (26, 28) while they are simultaneously being retained in a condition of being clamped by the inflatable sets (32, 34) of the diaphragm members (40, 42). <IMAGE> |
