Abstract
A strapping machine comprises a return roller having a high friction outer peripheral surface and a feed roller having a low friction outer peripheral surface which are contacted with each other under pressure and the return roller is disposed in free condition during the rotation of the feed roller in one direction and when the feeding resistance of the band is increased, the band is slipped on the outer peripheral surface of the feed roller to prevent the feeding of the band and in order to tighten the band around the package, both of the rollers are reversely rotated at a high speed to tighten the band around an object to be packed and then continuously rotated at a low speed to impart high torque to the band for an attainment of further tightening thereof.
