Adhesive Correction Tape Cartridge

The compact cartridge shown feeds adhesive, lift-off correction tape in a manner eliminating slack because neither of the spools moves independently of the other. The adhesive side of the take-up roll rests against and drives the non- adhesive side of the supply spool.

The cartridge is shown from the top with the top wall removed. The spools in solid lines represent a full supply spool 1 and an empty take up spool 3. The dotted lines show the condition when virtually all of the tape 5 has been used. An arm 7, pivoted to the bottom wall 9 by a vertical end 11, has an opposite vertical end 13 on which supply spool 1 pivots. Spring 15 is mounted to bottom wall 9 at a point spaced from end 11.

In the known manner, a spiked driver 17, which is part of the typewriter, engages the outside of take-up spool 3 at an open side of the cartridge. Take-up spool 3 has a central hub 19 which is engaged in slot 21 of bottom wall 9.

In this embodiment, spring 15 is effective to bias arm 7 toward take-up spool 3 with sufficient force to achieve firm engagement of supply spool 1 with take-up spool 3, while moving take-up spool 3, guided by slot 21, to the side of the cartridge. The side wall 23 of the cartridge has an opening 25 large enough to permit driver 17 to engage take-up spool 3, but small enough that the wall 23 forces take-up spool 3 to move inward as it enlarges.

Tape 5 is guided over post 27 to spaced guide arms 29 which position tape 5...
