ABSTRACT:
An improved strapping machine has a barrier for stopping travel of the strap at a precise location, a sensor which is activated by contact of the strap with the barrier so as to terminate operation of the strap feed means and a guide means for preventing buckling of the strap within the sealing assembly portion of the machine. In another aspect of the invention the clamping device has a first gripper located in fixed position during feeding and clamping, and a second gripper which is pivotable from a guide position to a clamping position. In a preferred form, one end of the second gripper bar serves as a shear anvil which co-acts with the blade to sever the strap. The shear anvil is adjustable so that the gap between the blade and anvil may be regulated to compensate for wear.
