Abstract

Conventional spiked driver manufacture for ribbon cartridges is expensive, necessitating the placement of the spiked driver externally of the cartridge or adding to the cost of the ribbon supply if the spiked driver is located internally of a throw-away cartridge. Described below is a spiked driver which is inexpensive to manufacture.

Spiked Ribbon Driver Assembly

Conventional spiked driver manufacture for ribbon cartridges is expensive, necessitating the placement of the spiked driver externally of the cartridge or adding to the cost of the ribbon supply if the spiked driver is located internally of a throw-away cartridge. Described below is a spiked driver which is inexpensive to manufacture.

Turning now to the drawing, the spiked driver assembly may be formed of a plastic shaft 10 having a major barrel portion 11, a reduced diameter stub shaft 12 and an enlarged base or flange 13. The flange 13 acts as a terminal end for a formed sheet metal portion 14 which has spike-like teeth 15 thereon. The teeth 15 are formed by lancing from the sheet metal 14. An opposing flange 16 having a central aperture 17 therein fits over and is connected (by any suitable means, for example, glue) to the stub shaft 12. This retains the sheet metal 14 in place. Of course, the shape and spacing of the teeth 15 in the sheet metal may be varied to produce optimum results with any particular ribbon employed in the ribbon cartridge.
