<p>A hole puncher and reinforcer for locating a length of adhesive tape in overlying relation to a sheet of paper, for punching a hole in the tape and paper, and for shearing and pressing the tape in position as a reinforcement for the punched holes. The device includes a plurality of spaced apart first disks operative to engage the adhesive side of the tape and pull it off a supply roll. A similar set of disks rotatable at a peripheral speed faster than that of the first disks engages the tape and directs it through a tape feed passage defined in part by thin fingers. The placement and rotation of the two sets of disks, and the presence of the fingers, enables advancement of the tape to the punch, shear and pressure mechanism without sticking or gumming.</p> |
