    (54) Strap winding disposal device


    (57) A strap coiling mechanism comprising a driven roller (1) having a serrated peripheral surface, a pinch roller (4) rotatably mounted at one extremity of a pivoted crank lever (8), said pinch roller (4) being biassed towards the driven roller (1) by means of a compressions spring (6) engaging the other end of the crank lever (8) and part of a supporting frame for the mechanism. The driven roller (1) and the pinch roller (4) between them define a nip (N) into which strapping (S) to be coiled is introduced. In the event that the strapping(s) includes a Seal (S′) or any other section modulus change the pinch roller (4) will be deflected away from the driven roller (1) against the action of the spring (6) to allow the seal (S′) to pass through the nip (N). A deforming roller (3) is rotatably mounted immediately behind the nip (N) and has a serrated peri­pheral surface which is engaged by the strapping (S) to form the strapping (S) into a self closing coil (C).
