Abstract
Abstract A slicing machine which can produce slices of varying thicknesses has a rotating circular blade mounted on a machine housing. A carriage is mounted on the machine housing adjacent the blade for reciprocating movement between two end positions in a direction parallel to the plane of the blade. A clamping device is mounted on the carriage for holding a material to be sliced and for advancing the material in a direction transverse of the path of movement of the carriage and toward the plane of the blade a distance which is a function of a predetermined slice thickness. The clamping means is advanced by a device having a continuously variable abutment attached to the machine housing. A rack is mounted on the carriage means for relative movement with respect thereto and is arranged to contact the abutment and be restrained thereby from movement with the carriage as the carriage moves to one of its end positions. A pinion rotatably mounted in the housing engages the rack for rotation thereby as the carriage moves relative to the rack when the rack is restrained by the abutment an angular amount which depends on the position of the abutment. An overrunning clutch is connected to the pinion and a screw is connected to the clutch for rotation therewith. The screw is connected to the clamping device by a follower member which engages in the threads of the screw and advances the clamping device only when the screw rotates.
