Patent number: 5536044Abstract: An apparatus for binding a plurality of sheets of paper together is disclosed. A pair of clamping plates presents one edge of the sheets for binding after a jogging plate aligns the edges. After a solid hot melt adhesive material sheet is placed along the edge of the sheets, a heating platen heats and melts the hot melt adhesive material sheet and causes the liquid adhesive to bind the sheets together. The method of binding the stack of a plurality of sheets of paper includes positioning a plurality of sheets between the clamping plates, vibrating the sheets to square and align their edges, clamping the aligned sheets of paper, presenting the aligned edge of the paper to the heating platen, placing an adhesive hot melt material sheet on the edge of the sheets, heating and melting the hot melt adhesive material sheet onto the edge, and removing the bound sheets from the apparatus.Type: GrantFiled: June 13, 1994Date of Patent: July 16, 1996Assignee: Minnesota Mining and Manufacturing CompanyInventors: Robert A. Luhman, Gary K. Kuhn, Kenneth J. Perrington, Karl M. Kropp, Michael W. Gruber

Patent number: 5312501Abstract: An automatic application device for dispensing an adhesive transfer tape with the liner removed includes a hub for rotatably supporting a roll of adhesive transfer tape and an application head for pressing the adhesive transfer tape unwound from the roll onto a product to which it is to be applied. An idler roller is disposed above the application head to pull the liner away from the application head. A motor driven take-up roller and corresponding nip roller are provided to pull the liner along its path over said idler roller away from the application head. A brake roller is provided along the path of the transfer tape between the roll and the application head to selectively stop the tape's advance. When the brake roller is released, the product to which the adhesive is applied pulls the tape underneath the application head, unwinding it from the roll. When the brake roller is stopped, the tape stops advancing and the adhesive strip carried on the liner is broken.Type: GrantFiled: August 17, 1990Date of Patent: May 17, 1994Assignee: Minnesota Mining and Manufacturing CompanyInventors: Michael W.
