ABSTRACT:
A strap binding a plurality of articles together is automatically cut and removed by gripping the strap between two counter-rotating rollers and cutting the strap by using an oscillating cutting blade. The two counter-rotating rollers are then operated to advance the cut end of the strap into a cylindrical recess of a collecting device to cause the strap to be coiled up within the recess. The coiled strap which is of a thermo-fusable material is then heated locally to cause adhesion between the adjacent turns. The coiled strap which is now in a stable, coiled condition, is then ejected from the apparatus.
