  • Patent number: 7316403
    Abstract: A workpiece holding apparatus comprises a body, a cartridge assembly carried by the body and a sleeve. The cartridge assembly comprises at least one sealing member and a bladder supported by a retainer and at least partially defining a fluid chamber that houses a pressurized fluid. At least one annular seal is axially provided between the bladder and the sealing member(s). The annular seal(s) correspond with a sealing member, which engages the annular seal(s) upon adjustment of the sealing member. A seal is formed between the sealing member and the bladder that prevents fluid from escaping the fluid chamber. The annular, cylindrical sleeve engages a workpiece when the fluid chamber houses a pressurized fluid, which exerts a radial force against the bladder to the sleeve and into engagement with the workpiece.

  • Patent number: 6470942
    Abstract: The present invention is designed to effectively band ornamental trims onto panel edges, such as those of furniture tops. The present invention utilizes pneumatic forces to hold the ornamental trims against the panel edges instead of traditional clamps, resulting in asserting a uniform pressure press-fitting the trims against the panel edges along a good length of the trims instead of merely along several points of the trims. furthermore, since the contacting surface of the present invention is made of a soft material, it would not leave any pressmarks or indentations on the trims as can left by a hardened clamp.
