ABSTRACT:
Large cylindrical bales of hay, straw, or other forage or fodder are usually wrapped with a filament-type product, typically twine, or a sheet-type product, typically netwrap material, after a bale has reached a predetermined size. A method and apparatus are disclosed that permits the bale to continue to form during part of the wrapping process. A delay occurs between the initiation of the wrapping step and the alarm for the operator to stop the forward movement of the baler. By inserting the wrap material to an entry throat of the baler, new crop material may be added to the bale while the leading edge of the wrap material travels around the bale. The operator is notified only when the feed of additional crop material needs to be stopped for the wrapping operation to conclude. The present invention is applicable to the use of sheet or filament wrapping materials for binding round bales.
