  • Publication number: 20060137545
    Abstract: A twine restrictor is disclosed having the advantages of simplicity and reliability. The twine restrictor is generally formed from solid or hollow stock. It is left free floating while being restrained sufficiently to avoid loss. Twine is passed over a substantially horizontal surface of a twine arm assembly and the twine restrictor is simply placed on the twine, providing a force up to a value equal to its weight on the twine. The twine restrictor is unaffixed and no springs are required.

  • Publication number: 20060048481
    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.

  • Publication number: 20050210855
    Abstract: When harvesting forage in the form of a large round bale, for instance, there are times in which a windrow of forage material lies outside the side boundaries of the bale-forming chamber. This may be due to the windrow being made wide by machinery having driven through it, or by wind, or because of the need to turn the forage harvesting equipment tightly. A wide pickup, notably wider than the width of the bale-forming chamber, provides a solution to this common problem. Dual augers at each end of the wide pickup provide the force to direct the forage into a narrower path, to enter the bale-forming chamber. The orientation and size of the augers permits the pickup header to reside in the same location it would if it was not wider than the baler. Tines or teeth of various rigidities and shapes are provided in the pickup for more effective pickup of the forage.
