SELF-REWINDING MACHINE CONTROL TAPE CASSETTE

摘要

A machine tool tape control includes an endless tape coil rotatably contained in a cassette casing which is mounted directly below the tape-reading head of the machine in an upwardly and outwardly inclined position such that an external loop of the tape leaves the inside of the coil, emerges through a medial slot in the rear side of the casing, and extends directly upwardly to the reading head and thence downwardly and back into the casing through an end opening therein, from which it extends tangently to the periphery of the roll and is wound externally thereon.
