Abstract: Pressure-sensitive tape attached to and extending beyond the front edge of a stiff card is removed by grasping the extending end in jaws in a wind-up roller. Rotating the roller winds the tape thereon, facing outward. Upon completion of winding, the roller is stopped, the clamp jaws released, and the wrap of tape is thrust off the end of the cantilevered roller.
