Tape Slitter

A test sample of one-half inch wide magnetic recording tape is hand-slit from the end of a wide jumbo roll, so that the sample may be tested.

Two rollers l0 and ll are bearing-supported by base plate l3 and vertical supports l4. Upper roller l0 is coupled to hand crank l5, and includes metal slitter blades l6 and l7, formed of hardened tool steel or carbide, 0.020 inch thick. The lower roller includes two similar slitter blades l8 and l9, as well as rubber support ring 20. Ring 20 is of a smaller diameter than blades l8 and l9, whereas the portion 2l of the upper roller is of the same diameter as its blades l6 and l7.

The end of a jumbo roll is threaded between rollers l0 and ll, by turning crank l5. The slitting of a one-half inch wide piece of tape can then be continued either by continued operation of the crank, or alternatively, by merely pulling on the piece of the jumbo roll then threaded between rollers l0 and ll.
