Patent ID: 6923235

Claim:
A device for displacing an adhesive tape comprising: a support for a spool of the tape; and a pressing means for pressing the tape; and a first drive means and a second drive means for displacing the tape, the first and second drive means being driven by common driving means; wherein: each of the first drive means and the second drive means defines a continuous trajectory passing over a respective drive wheel and at least one respective idler wheel, a contact portion of the first drive means and an contact portion of the second drive means each contacting the respective drive wheel and the at least one respective idler wheel; the pressing means having a central rotational axis perpendicular to a central rotational axis of each of the respective drive wheel and the at least one respective idler wheel, the central rotational axis of each of the respective drive wheel and the at least one respective idler wheel are parallel; an adhesive face of the tape is pressed against an edge portion of the first drive means and an edge portion of the second drive means; the edge portion of the first drive means and the edge portion of the second drive means are parallel to each other and spaced apart from each other; the edge portion of the first drive means and the edge portion of the second drive means are substantially disposed in a plane parallel to the central rotational axis of the pressing means and perpendicular to the central rotational axis of each of the respective drive wheel and the at least one respective idler wheel, the adhesive face of the tape also being substantially disposed in the plane; the edge portion of the first drive means and the edge portion of the second drive means are spaced from each other by a distance less than a width of the adhesive tape; and the edge portion of the first drive means and the edge portion of the second drive means are in contact with longitudinal borders of the tape, so that movement of the first and second drive means causes movement of the tape.
