ABSTRACT:
A fabricated clamp bar that goes into a channel in a machine roll to hold a knife, anvil, or other tool in the channel. The bar has an internal cavity or chamber in one side of the bar. The chamber has an exposed movable outer side wall placed at the side of the machine roll channel. When the internal cavity or chamber is pressurized with a non-compressible fluid such as grease, the movable side of the chamber is forced outward causing the bar to expand in width, causing the clamping side of the bar to trap the tool to be held in the roll against the side of the channel in the roll of the machine. Also disclosed is the use of an intermediate buffer block between the clamp bar and tool to be held in the roll. Spring loaded members may lightly clamp and pre-position the tool via strategically located holes at each end of the tool until pressure is applied to the fluid.
