TWINE WRAPPING APPARATUS FOR A ROLL BALING MACHINE

摘要

A twine wrapping apparatus (42) for a roll baling machine includes a shuttle member (50) which carries a gear rack (86) that intermeshes with a pinion (68) connected to a twine dispensing member (56) such as a twine tube. When the shuttle member (50) is moved generally transversely of the roll baling machine, the pinion (68) is rotated by the gear rack (86) resulting in pivoting movement of the twine tube (56). Preferably first and second twine dispensing members (56) and associated pinions (68) and gear racks (86) are provided; the first and second gear racks (86) being disposed on the shuttle member (50) to pivot the twine dispensing members (56) concurrently in opposite directions when the shuttle member (50) is moved transversely. A twine cutting and clamping apparatus (62) is provided including an arm (114) having one edge which cooperates with a cutting member (134) to cut twine therebetween. The arm (114) has another edge which cooperates with a resilient member (136) to clamp twine therebetween. Preferably a dual twine cutting and clamping apparatus (62) is provided including a pair of arms (114) and a pair of intermeshing spur gears (118) connected, respectively, to the arms (114). A lever (122) is connected to one of the arms (114) to pivot it when the shuttle member (50) is moved transversely. The spur gears (118) cause concurrent pivoting of the other arm (114) when the one arm (114) is pivoted by the lever (122).
