ABSTRACT:
A cassette winding machine includes a tape winding unit for winding a predetermined length of tape from either a first supply reel or a second supply reel into a cassette. The first and second supply reels are rotatably mounted on hubs on the machine. A tape support holds the tape from the first supply reel as well as the tape from the second supply reel. The tape support is located on the supply reel side of the cassette winding machine between the supply reels and the tape winding unit. The cassette winding machine also includes a tape threading assembly that has a gripper device. The gripper device selectively grips and releases tape from either the first supply reel or the second supply reel. The tape gripper device grasps a selected one of the first and second tapes at a point near the tape support. Subsequently, the tape threading assembly moves the gripper device, which is holding the free end of the selected tape, from the supply reel side of the cassette winding machine to the opposite side of the cassette winding machine beyond the tape winding unit. Hence, the tape threading assembly moves the selected tape from one side of the cassette winding machine to the other side and places the selected tape across the tape winding unit. The tape winding unit may then utilize the selected tape for tape winding operations. Preferably, the tape threading assembly moves the gripper device ina substantially straight line between its initial threading position and its final threading position without encountering any guide rollers or other components.
