Abstract
A strapping apparatus advances a band around an object to be strapped and then retracts and tightens the band against the object. Retraction of the band is performed by a driven roller. A touch roller is displaceable toward the driven roller to press the band thereagainst. The outer periphery of the driven roller comprises a flexible high friction material, and a circumferentially extending low friction material embedded in the high friction material and normally projecting radially outwardly therebeyond. When the band travels against the low-friction material it encounters little resistance. When the touch roller pushes the band against the driven roller, the low-friction material is pushed radially inwardly, enabling the band to contact and be driven by the high-friction material.
