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.

Abstract: A mask for and method of masking a workpiece which has some predetermined continuous demarcation zone whereby precise painting of a first area disposed on one side of the zone is accommodated. The mask includes opposed faces and a peripheral edge or contour having substantially the same conformation as the demarcation zone. One face includes a narrow band of adhesive extending therearound adjacent the peripheral edge. The mask is accurately positioned on the workpiece to precisely mask a second area thereof along and on the other side of the demarcation zone from the workpiece first area. The first area may then be painted and the mask thereafter removed. To accommodate application in production environments, the other or outer face of the mask may be release coated so that a stack or pad comprised of a plurality of identical masks may be provided at a workstation for individual application to consecutive workpieces.

Abstract: A method of masking a workpiece at a demarcation zone to facilitate precise spray painting of a workpiece first area on one side of the zone. The method includes providing a mask which has an adhesive backing on one face thereof and a protective liner removably secured to the adhesive backing. The liner is cut or severed so that the resultant sever line has the same conformation therealong as that desired for the demarcation zone. That section of liner associated with the portion of the mask to be affixed to a workpiece second area on the opposite side of the demarcation zone from the workpiece first area is removed from the mask. Thereafter, the mask may be affixed to have the liner sever line precisely aligned with the demarcation zone. Pressure is exerted against the mask at a thin pressure zone coextensive with the demarcation zone to automatically lift that portion of the mask which overlaps the workpiece first portion at and along the demarcation zone to generally form an acute angle therewith.
