Strap winding disposal device |
摘要 |
A strap coiling mechanism comprising a driven roller one having a serrated peripheral surface, a pinch roller for rotatably mounted at one extremity of a pivoted crank lever 8, said pinch roller being biassed towards the driven roller 1 by means of a compression spring 6 engaging the other end of the crank lever 8 and part of the 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 includes a Seal' or any other section modulus change, a pinch roller 4 will be deflected away from the driven roller 1 against the action of the spring 6 to allow the seal to pass through the nip N. A deforming roller 3 is rotatably mounted immediately behind the Nip and has a serrated peripheral surface which is engaged by the strapping S to form the strapping into a shelf closing coil C.
