ABSTRACT:
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 provide 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. A compensation roller provides that when the head is lifted the tape is maintained in a fixed position relative to the head so that the leading edge of the adhesive on the tape liner returns to the proper position when the head is lowered.
