ABSTRACT:
A feed roller is usually rotated at a high speed; a return roller is fitted to a return shaft rotated at a low speed through a one-way clutch; a rocker roller driven at a high speed is brought into press-contact with the return roller so that the return roller is rotated at a high speed in accordance with the high speed rotation of the rocker roller thereby performing the primary tightening operation for a band; then, the return roller is engaged with the return shaft by the function of the one-way clutch when the rotational speed of the return roller coincides with that of the return shaft, thereby performing the secondary tightening operation with a strong pulling force. The strapping machine having the above mentioned construction provides noiseless and speedy operations for strapping the band around a package.
