ABSTRACT:
A device, for feed and tensioning a strapping band about a package in a strapping machine, is disclosed. The machine includes a feed roller which is actuately deflected when the band is placed under tension by a tensioning device. The tensioning device includes a pair of counter rotating v-belts between which the band passes and a pressure device which causes the band to be gripped by the v-belts thus placing it in tension. As the tension on the band increases the pressure exerted by the pressure device is proportionately increased by an angular lever to which the feed roller is connected, which in turn acts on a slidable rod which, through a toggle lever, actuates the pressure device. The machine also includes a sealing and cutting device which is actuated subsequent to the tensioning of the band and which, through a rocker lever, causes the toggle lever to release the pressure on the pressure device prior to the cutting of the rear end of the band.
