The wafering machine is provided with a two-piece housing for mounting the spindle of the saw blade. One housing part is mounted on a fixed axis of a support shaft while the other part is pivotally mounted relative to the first housing part about a pivot axis perpendicular to the support shaft axis. Locking screws are provided to fix the two housing parts together while adjustment blocks with adjusting screws are provided to carry out a rotational adjustment of the rotatable housing part. Rotation of the housing part causes the axis of the spindle to be brought into alignment with the fixed axis of the pivotal cutting motion such as to maintain the plane of the cutting portion of the saw blade parallel to the pivotal cutting motion.

Housing for mounting a spindle of an internal diameter saw blade

An improved tensioning device is provided for use in an inner diameter saw blade housing. A tensioning ring, disposed in an annular clamping member, is internally threaded at plurality of locations along its circumference. An associated plurality of screws, disposed in cylindrical recesses in the clamping member, threadedly engage the internal threads. The screws may be turned through an opening in the clamping member having a diameter smaller than the screw to thereby precisely tension the blade as desired. Since the screws are captive within the clamping member, migration of the tensioning ring relative to the blade is prevented. Further, the screws do not protrude from the surface of the clamping member and the threaded portions of the screws are closed off from the ambient such that foreign matter cannot enter the clamping member and interfere with the tensioning process.
