ABSTRACT:
A portable roll-riding tape cutter comprises two cooperative collapsibly interengageable members, one of which engages with the outer perimeter of the tape roll and the other of which engages with the inner diameter of the ring-shaped core of the roll. Telescopically engageable legs on the members straddle the sides of the roll and are equipped with complementary separably interdigitating retaining ribs. One or both of the members may be provided with curved bearing surfaces substantially matching the roll surface curvature to facilitate maximum severed tape strip utilization from the roll by use of the assembly. Clearance recesses in the legs facilitate digital manipulation and improve the resiliency of the leg. Channels on the legs of one of the members and complementary base bars on the other of the members carry the interdigitating retaining ribs and also maintain the members against displacement relative to one another circumferentially of the roll.
