Abstract

Tension is applied to an inking ribbon 10 as it is drawn from a cassette 12, a portion of which is shown in the accompanying figure, by magnetic means such as the pair of magnets 14 or pieces of ferromagnetic material, which are loosely positioned in cavities 16 on either side of the ribbon. The magnets are so arranged that they attract each other and pinch the ribbon 10 therebetween, thus providing the desired drag on the ribbon, Which produces a substantially constant tension therein as the ribbon is drawn from the cassette 12.
