Blending tape dispenser

Abstract

Layered blending tape comprised of a mask layer having an adhesive layer on one surface thereof, an elongated mask section adhered to a portion of the adhesive layer longitudinally thereof, and a release strip section releasably adhered to the remaining portion of the adhesive layer is spirally wrapped around a core to form a roll. This roll is mounted on a tape dispenser. The dispenser includes a tape roll mounting assembly and a guide roller-engaging surface assembly for separating the release strip section from the adhesive layer during a tape dispensing operation. The tape roll mounting assembly includes a hub rotatably mounted to a frame by an axle and retained by a retaining nut. A coil spring received over the axle is interposed between the retaining nut and the outer side face of the hub. A brake pad is operatively interposed between the other hub side face and the frame. The forward end of the tape is threaded through the guide roller-engaging surface assembly so that as tape is unrolled from the roll and withdrawn from the dispenser, the release strip section is continuously separated or removed from the tape adhesive layer to expose that portion of the adhesive layer disposed therebeneath. Tape backlash is prevented by adjusting the coil spring compression by means of the retaining nut. Tape dispensed from the device may be advantageously used for marking some workpiece prior to painting. Also, the device may be operatively mounted adjacent a supply of masking paper so that the tape is in general alignment with a lateral side edge of the paper. This then facilitates mating and simultaneous dispensing of the tape and paper.
