Abstract
A band saw and an assembly having an interchangeable casing bearing the saw blade, the saw comprising a leading wheel and at least one led wheel on which the blade is mounted; one of the wheels can be moved by tensioning means between a blade-tensioning position and an action-taking position in which the assembly comprising the casing and the blade can be interchanged.
Claims9
A band saw comprising a plate supporting the workpiece to be sawn, a closed saw blade defining a cutting plane and supported by at least two wheels, one of which is a leading wheel rotated by control means, the saw also having means for moving the saw blade in relation to the workpiece to be sawn in the cutting plane, wherein the saw also comprises blade-tensioning means enabling at least one of the wheels to be moved between a tensioning position and an action-taking position, and a detachable casing which receives such blade, the casing and the blade which it contains forming an assembly which can be interchanged as a unit without any other demounting when the tensioning means retain such wheel in the action-taking position.
An assembly provided for use in a band saw, wherein it comprises a closed saw blade and a casing which receives such blade, the casing comprising blade-retaining means against which the blade is resiliently stressed in the absence of blade tensioning, the retaining means being such that the blade can be moved away from them when is it tensioned, the casing including a plate disposed on the blade side remote from its toothing, the retaining means comprising lugs which project from such plate, outside the saw blade and beyond its toothing, such lugs having ends curved inwardly to opposite the toothing.
