Abstract (en)
A strapping machine comprises an outlet (10) for a strap to be wound around a product and a system (11) for delivering, recalling and tensioning the strap. This system (11) comprises a drive unit (13) for delivering and recalling the strap, having a first drive wheel (14) and a counter-pressure wheel (15) which rests, under the action of a spring member (20), against the first drive wheel (14) with the strap (12) arranged in between so as to guide it a first speed determined by the first drive wheel (14). A second tensioning drive wheel (16) is also provided and is normally kept spaced from the counter-pressure wheel (15) by means of a further spring member (17). The strap (12) passes around the drive wheel (16) directed from the drive unit (13) towards the outlet (10) of the strapping machine. Once a predefined tension value of the strap being recalled is exceeded, the second tensioning drive wheel (16) moves against the action of the further elastic member (17) and rests and pushes against the counter-pressure wheel (15) with the strap (12) arranged in between, so as to disengage the counter-pressure wheel (15) from the first drive wheel (14) and guide the strap (12) during tensioning at a second speed determined by the second drive wheel (16).
