The present invention relates to a prestretched polyethylene film having a longitudinal stretch ratio of from about 1:2 to about 1:4 and having a longitudinal elongation capability of at least 170%, said elongation capability comprising an elastic component. The invention also relates to a method for producing said film and to a method of wrapping compressed bulk material such as a round bale using said film, the method comprising further stretching the prestretched film and applying the film around the compressed bulk material in direct contact therewith. The film according to the invention may be used as a net replacement film and allows increasing the efficiency and the economics in the baling process by allowing faster baling, use of a lesser amount of wrapping film and/or improved protection of the product.

The bale wrapping assembly for a round baler includes at least one twine inserter coupled to a drive. The drive is configured to drive the at least one twine inserter along a movement trajectory to intermittently introduce one or more twines into an outer circumferential surface of a completed bale. The one or more twines are positioned at the at least one twine inserter.

A round baler includes a first roller and a second roller that define a gap therebetween and are arranged to position forming belts immediately adjacent to a baling chamber. A third roller is arranged to position the forming belts radially outward of the baling chamber. The forming belts move along a belt path in sequence from the first roller, to the third roller, and then to the second roller, such that the baling chamber is not bounded by the forming belts in the gap between the first roller and the second roller. A net guide is radially supported by both the first roller and the second roller and laterally positioned between an adjacent pair of the forming belts. The net guide extends across the gap to guide a net material across the gap and prevent the net material from following the forming belts away from the baling chamber.

A bale wrapping system that includes a belt that rotates to form and drive rotation of a bale of an agricultural product. The bale is configured to be wrapped with a wrapping layer of a bale wrap while rotating on the belt. A first portion of the wrapping layer overlaps a second portion of the wrapping layer while disposed on the belt. A glue system sprays a layer of glue onto the wrapping layer. The layer of glue enables the first portion of the wrapping layer to couple to the second portion of the wrapping layer.

A bale wrap includes a wrapping layer configured to wrap around a bale of agricultural product, such that a first portion of the wrapping layer overlaps a second portion of the wrapping layer. Additionally, the bale wrap includes an adhesive layer embedded on or in the wrapping layer and configured to be activated by an adhesive activation mechanism. Activation of the adhesive layer enables the adhesive layer to bond the first portion of the wrapping layer to the second portion of the wrapping layer.

A prestretched polyethylene film is provided having a longitudinal degree of prestretching in the range of from 100% to 400% and a remaining longitudinal elongation capability in the range of from 100% to less than 300% as determined according to ASTM D882. The film comprises at least 25% by weight of a linear low density polyethylene (LLDPE) substantially free from long chain branching (LCB) and having a density below 915 kg/m.sup.3. The film is particularly useful as a net replacement film in the baling of compressed bulk material, such as silage, and may offer to users improved flexibility and reliability and/or increased yield.

A method of identifying a bale of material includes capturing an initial image of a region of an initial bale with an initial image sensor and identifying a unique band pattern of at least one multi-colored band of the initial bale. The identified unique band pattern is associated with the initial bale. Data related to the initial bale is associated with the identified unique band pattern. The identified unique band pattern of the initial bale may then be used as an identifier of the initial bale. A second image of the bale is captured and analyzed to determine if the second image includes the unique band pattern of the at least one multi-colored band, thereby identifying the bale in the second image as the initial bale. The data associated with the initial bale may then be retrieved by an operator.

In a continuous roll of wrapping material for crops such as cotton or hay, or other objects, the individual wrapping segments are arranged so that a closing adhesive is part of a sealing accessory and otherwise protected by other structures of the sealing accessory until the point when this closing adhesive is to be exposed for securing a wrapping segment to itself, for example when encircling a subject bale harvested from a field, wherein adjacent wrapping segments separate from each other either at a point of weakness associated with perforations and the like.

The invention uses a new system which cuts and unlocks a wrapping material (PE film) for cotton in a continuous manner in cotton harvesting, and a new method in production of such film. The film consists of many segments that make many bales of cotton. The film is separated with perforation by laser or other methods. A double sided adhesive is used to glue the bale at the end of it, which is covered by a folded bridge. The bridge connects the both ends of the segments of the film. When perforated film is torn at a signal by the harvest machine, the bridge is unfolded as a leading edge for the next segment after a brief bridge linkage of both segments. The way of folding the bridge is key part of the invention, which accurately uncovers the end adhesive for the new bale and reduces the problem of tangling of the film at the time of separation.

A module builder of an agricultural vehicle includes a chamber operable to support and form a product. A wrap is feedable into the chamber through a pinch point, the pinch point partially defined by a rotatable roller. A belt at least partially defines a wrap path. The wrap is configured to move along the wrap path to surround the product in the chamber. A gas flow system and/or a reversing belt is operable to direct the wrap from the pinch point toward the wrap path.
