摘要： A device for tensioning in a radial direction an annular sawblade contained in an assembly comprising a plurality of annular rings. The sawblade is retained in the assembly by a mount ring, a tension ring and a lock ring. The assembly is fixed in position in the device by means of the mount ring. The tension ring is coupled to a torque-producing means whereby, when the tension ring is rotated relative to the mount and lock rings, an annular extension on the tension ring will be moved axially and into engagement with the surface of the sawblade. The force applied to the surface of the sawblade by the annular extension will cause an annular deformation in the form of a rib to be produced which results in the sawblade being tensioned in a radial direction.

摘要： A device for retrieving a thin slice or wafer of material that has been cut from a billet and for transferring it to a storage receptacle comprises two pivotal members. A first pivotal member retrieves the slice after cutting and moves it along one side of an annular cutting member into a transfer position relative to the inner diameter of the annular member. A second pivotal member takes the slice at the transfer position and moves it axially and then in an arcuate path to a storage receptacle where it is released. The slice of material is retained on the pivotal members by suction. Suitable circuitry controls the application of the suction in proper timed relation to the movement of the pivotal members. A movable support member for the billet is also pivotally mounted so it can move the billet into a position in which it is spaced from the annular member on movement of the latter to its home position, thereby preventing damage to its exposed surface by contact with the annular member. In its home position the billet is moved axially to establish the thickness of the slice to be cut next and then radially relative to the annular member in another cycle of operation to cut the slice. Movement of the support member is also controlled by circuitry interconnected with that for controlling movement of the pivotal members.
