    Abstract: An adhesive erasing ribbon employed in a typewriter is reliably tracked and fed by a supply and takeup mechanism that positively maintains resilient tension on the ribbon. A spring device acting against a cam in the form of a multi-toothed ratchet, positively maintains continuous tension on the ribbon regardless of any tendency caused by vibrations and continued stress for the ribbon to loosen during extended periods of non-feeding operation. The tension maintaining mechanism and the ribbon supply spool are mounted on a tilting platform to minimize the exposed length of adhesive ribbon and thereby minimize its deterioration.

    Abstract translation: 在打字机中使用的粘合剂擦除带可靠地通过供应和收紧机构进行跟踪并馈送，该供应和收紧机构可以在带上保持弹性张力。 弹簧装置作用在多齿棘轮形式的凸轮上，无论在长时间的非进给操作期间由于振动引起的任何趋势和带状物的持续应力松动，都可以正确地保持带上的连续张力。 张力维持机构和色带供应卷轴安装在倾斜平台上以最小化粘合带的暴露长度，从而使其劣化最小化。
