Abstract: A clutch device for tool holders or tool chucking or workpiece chucking devices is used for the releasable form-fitting engagement of a drive shaft, comprising a spindle of the tool holder or chucking devices, said spindle being coaxial with the drive shaft. The drive shaft and the spindle have separate dog elements, whereby, between the two dog elements, a clutch element is arranged that compensates for alignment errors between the drive shaft and the spindle and that can be moved in a limited manner between the drive shaft and the spindle. The clutch element is in form-fitting engagement with the dog elements of the drive shaft and of the spindle.

Abstract: A core cutter machine for cutting cylindrical cores of predetermined widths is disclosed. The core cutting machine has a plurality of mandrels of predetermined diameters. Each of the mandrels receives a core tube to be cut. A cutter or knife assembly is mounted adjacent each of the mandrels and a support assembly is positioned adjacent each of the mandrels in opposed relationship to the cutter assembly.

Abstract: A machine for cutting slices from a cylindrical workpiece such as a log of pressure sensitive tape. The machine has a machine frame and a mandrel on the frame for holding and rotating the cylindrical workpiece. A disc shaped cutting blade is mounted on a carriage and is movable to cut the workpiece into material slices. The carriage is movable to shift the cutting blade to locations along the mandrel at which the workpiece is cut into slices. A drive mechanism is connected to the carriage assembly for moving the carriage assembly along the mandrel. That drive mechanism has a drive handle which can be manually gripped to disengage a drive rack and pinion and so enable movement of the carriage assembly in either direction along the mandrel. A one-way clutch mechanism connects the handle to the pinion so that rotation of the handle in alternate directions incrementally moves the carriage assembly in one direction only along the mandrel.
