Abstract
A roller unit for controlling band-feeding of an arch-type strapping machine, wherein the high-speed pulling back and strong tightening operations can be efficiently proceeded by reducing friction and impact force between a band and a return roller at the transition time between the high-speed pulling back and the strong tightening. The roller unit is so constructed that a return roller is driven via an one-way clutch, wherein a high-speed return roller of small torque and high speed return roller can be pushed to contact to the upper portion of the return roller and a return rocker roller can be pushed to contact to the lower portion of the return roller.
