<p>A definite length transfer adhesive dispenser for applying predetermined lengths of a tranfer adhesive to a substrate is disclosed. A supply roll of the transfer adhesive comprising a supply core, and a length of backing strip wound around the core is also disclosed. The transfer adhesive dispenser comprises a housing having a base wall, side walls, an open end, inner and outer surfaces, and a supply roll hub. The dispenser includes a mechanism for restricting free rotation of the supply roll about the hub. A take-up assembly is present comprising a take-up hub and a take-up core. The take-up core rotates about the take-up hub in an advancing direction. Path structures define a path for the backing strip from the supply roll hub to the take-up hub. An application mechanism is present comprising an application member including an application surface which forms a length of the path for the backing strip. An actuation member having a distal surface is mounted for manually actuated reciprocal movement relative to the housing between (1) a projecting position with a distal surface projecting past an open end of the housing to afford positioning the application surface opposite a substrate and (2) a retracted position with the application surface and the distal surface of the actuation member generally aligned so that the predetermined length of transfer adhesive on the backing strip may be pressed into contact with the substrate positioned opposite the application surface. An advancing mechanism is coupled between the actuation member and the take-up assembly for advancing the predetermined length of the backing strip and the transfer adhesive along the path.</p> |
