ABSTRACT:
Methods and apparatus for guiding an advancing tape in either one of two opposite directions employ a hollow tape guide member, a post through such hollow tape guide member, a sleeve around such post inside the hollow tape guide member, and a tape guide surface at an end of the tape guide member peripherally thereof and at an angle thereto. A fulcrum extends circumferentially around the post at a predetermined location offset in a direction away from the tape guide surface from a central location corresponding to a longitudinal center line of the tape, for supporting the sleeve for omnidirectional tilting motion relative to a plane intersecting the post at the predetermined location. The hollow tape guide member is mounted on the sleeve with spaced bearings located at opposite sides of the mentioned plane, for rotation about the post and tilting motion with the sleeve. The advancing tape is placed into continuous contact with the tape guide surface by contacting the tape guide member continuously with the advancing tape to rotate and tilt such tape guide member with the tape in either direction of advance.
