Has two endless strap drives (A,B), whose strap sides (12a,13a) cooperate with the adhesive face of the band (10), are rectilinear, parallel and separated from the active juxtaposed strap and have a side (12b,13b) in the same plane as that of the juxtaposed strap. The two active straps (12a,13a) are separated from each other by a distance less than the width of the adhesive strip (10) so that their sides (12b,13b) cooperate with the longitudinal edges of the strip (10). Displacement mechanism, for an adhesive band/strip, having a support for a adhesive band (10) spool (9) and two strap drives (A,B) driven by common motor (20). The straps follow and endless trajectory by passing over a drive roller (14 or 15) and a free roller (16 or 17). During the trajectory of the strap the adhesive face of the band (10) is pressed against sides (12a or 13a) of the straps. |
