ABSTRACT:
A tape guide which includes a roller having a fixed lower flange and a tape contacting portion having a width less than the width of the tape. A compliant member formed from a flat spring is mounted on the top of the roller opposite the flange. The compliant member includes an outwardly and upwardly tapered peripheral portion extending beyond the diameter of the tape contacting portion of the roller. Since the tape width is greater than the width of the tape contacting portion of the roller, the tape is forced against the tapered portion of the compliant member. The compliant member thus biases the tape downward against the lower flange by applying a uniform distributed load against the upper edge of the tape. The tape is prevented from being vertically displaced regardless of variations in the width of the tape. Variations in the wrap angle will not affect the loading on the tape.
