ABSTRACT:
A round baler is disclosed as including an improved bale wrapping mechanism that provides positive feeding of the wrapper at the start of the wrapping cycle. The mechanism includes a shiftable frame carrying a pair of feed rollers, with one of the rollers being brought into engagement with a stretch of the belts moving toward the baling chamber when the frame is shifted to a starting position. The wrapping mechanism is configured so that the belt stretch and the one feed roller cooperatively define a nip that is located downstream along the wrapper path from the nip defined between the feed rollers. A cutting assembly is disposed to sever the wrapper at a point spaced downstream from the nip defined between the belt stretch and the one roller, thereby insuring the wrapper presents a free end that is trapped between the one roller and the belt stretch when the frame is moved to the starting position. The wrapper is consequently gripped between the belts and the one feed roller so as to be pulled from its supply.
