An engageable pawl member is provided so as to be swingable about a supporting shaft so that a pawl tip is movable along a moving path for a strapping band. The engageable pawl member is pulled forwardly in a swinging direction by a helical tension spring to push the pawl tip against the strapping band. The engageable pawl member shifts forwardly, following the movement of the strapping band in a feeding direction, and the strapping band is sandwiched and held between the engageable paw member and a holding guide. Then, the engageable pawl member follows the movement of the strapping band in a direction to pull back, and the engageable pawl member shifts backwardly so that the pawl tip moves in a direction out of the moving path for the strapping band.

Operable sealing mechanism for a strapping band

Arch type strapping machine

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.

Arch type strapping machine having an adjustable speed band tightening

An arch type band guide includes corner elements and straight elements each having the same shape and the same size, wherein the elements are connected in a manner capable of swinging in an arch unit, whereby various sizes of band guide can be easily fabricated depending on the size of articles to be packed.
