摘要

SYSTEM FOR AUTOMATICALLY ENVELOPING A LARGE ROUND BALE WITH A WRAPPING An optional mechanism for enveloping a bale, in the bale chamber of a large round baler, with a wrapping material such as plastic sheet or net is provided on a baler having an automatic twine tie mechanism. The optional mechanism is embodied such that it utilizes mechanical and hydraulic controls of the twine tie mechanism for effecting automatic engagement of a normally disengaged drive roll drive for feeding wrap material into the bale chamber in response to a bale reaching a desired diameter in the chamber and for automatically severing the wrap material once a length thereof sufficient for encompassing a bale a desired amount has been dispensed as determined by the time it takes a speed-controlled hydraulically operated twine arm to swing from one side to the other of the bale chamber.
