Abstract

A twin blade mounting and tensioning apparatus is disclosed wherein twin inside diameter cutting blades for sawing crystalline rod materials are mounted with annular clamping-tensioning members which clamp the twin blades between the members with the clamped twin blades having an outer annular shim and an inner annular shim located therebetween in a spaced apart relationship defining an annular fluid expansion chamber, the annular clamping-tensioning members having recessed annular chambers in circumferential alignment with and located axially outward from said expansion chamber, the expansion chamber separated from the recessed chambers by the twin blade walls which are flexible and deformable within said recessed chambers through the action of pressurized fluid means.

Dependent claims

A twin blade mounting and tensioning apparatus comprising first and second annular clamping-tensioning members for clamping a first annular blade and a second annular blade, an outer annular shim and an inner annular shim located between the first and second blades, said shims being spaced apart defining an annular fluid expansion chamber between the twin blades, said annular clamping-tensioning members in circumferential alignment and located axially outwardly from said expansion chamber confronting a first wall of each blade while said expansion chamber confronts a second wall of each blade, said annular clamping-tensioning members having annular recessed chambers in register with the fluid expansion chamber, at least one of said annular clamping-tensioning members having fluid entry and exit channels which are in communication with the annular fluid expansion chamber, said blade walls between the expansion chamber and said recessed annular chambers being flexible and deformable within said recessed chambers.
