Abstract:
A crushing apparatus for crushing closed cells in a pad material, comprising:first and second counterparts disposed contactable with each other, said first counterpart including a first frame, and a first flexible sheet member secured to said first frame, said second counterpart including a second frame which is rotatable around its one side, and a second flexible sheet member secured to said second frame, said first and second flexible sheet members being non-air permeable and contactable with each other so as to form an air-tight seal condition between said first and second flexible sheet members, one of said first and second frames having a suction opening which is able to be sealingly connected to a space formed between said first and second flexible sheet members;an air-sucking device connected to said suction opening so as to suck air from the space formed between said first and second flexible sheet members; anda conveying device disposed under said second frame to convey the pad material to be located thereon;wherein air in the space is sucked by operating said air-sucking device so as to crush the closed cells in the pad material under a condition where the pad material having the closed cells is placed in the space, and the pad material placed on the second counterpart is moved to said conveying device upon rotating said second frame around its one side.
