<p>A feed device for strapping bands for use in strapping machines is disclosed. A pressure device and a feed roller push the strapping band into a band channel behind the feed roller. A disengaging lever is connected to the pressure device so that when a loop in the band is formed in the band channel, it moves the disengaging lever causing the pressure device to be withdrawn from the band and feed roller permitting the band to reverse direction causing the loop to disappear.</p> |
