A wrapping assembly includes: a material roll that holds a roll of wrapping material; a duckbill assembly including a duckbill carrying a duckbill roll that draws material from a roll of wrapping material held by the material roll, the duckbill being movable between a first position and a second position; a duckbill actuator coupled to the duckbill that moves the duckbill between the first position and the second position; a variable brake associated with the material roll that applies a variable braking force to the material roll; and a controller operatively coupled to the duckbill actuator and the brake. The controller determines that a load on the duckbill actuator exceeds a threshold value and outputs a brake reduction signal to the brake so the brake reduces applied braking force to the material roll when the load on the duckbill actuator exceeds the threshold value.

A wrapping assembly for an agricultural vehicle includes a frame, a material support roll supported by the frame and configured to hold a roll of wrapping material, and a spreader roll assembly configured to spread wrapping material from the roll held by the material support roll and including a first roll supported by the frame and a second roll having at least one pivot. The at least one pivot pivotably couples the second roll to the frame and is positioned such that an exerted force from the wrapping material on the second roll causes the second roll to pivot toward the first roll and pinch the wrapping material between the first roll and the second roll.

An apparatus for processing bales, for agricultural machines provided with a chamber for forming a substantially cylindrical bale. The apparatus includes at least one structure for supporting a reel of banded material, of the type of a net, a polymeric film, and the like, designed to wrap the bale. The apparatus includes means of movement of a device for the transfer and delivery of an end flap of the reel to the forming chamber; such device is provided with an end blade which can move along a work path, from a first limit position, in which the blade is proximate to the reel supported by the structure, for the withdrawal of the end flap, to a second limit position, in which the blade is facing toward the chamber, for the delivery of the flap to the chamber, and vice versa, such limit positions having substantially the same height from the ground.

A bale wrap tensioning system includes a spindle that can be operatively coupled to a wrap material supply roll and a rotary hydraulic device that has a rotatable input shaft. The input shaft is coupled to the spindle for rotation with the wrap material supply roll. The bale wrap tensioning system includes a control valve that is operable to control a variable pressure of hydraulic fluid displaced by the rotary hydraulic device. The bale wrap tensioning system includes a controller for adjusting the control valve to alter the variable pressure of the hydraulic fluid displaced by the rotary hydraulic device.

A bale wrapping device for a round baler includes a wrapping material roller having a wrapping material. The wrapping material roller is able to be brought into engagement with a brake roller, and a cutting apparatus for cutting off the wrapping material from the wrapping material roller. A brake apparatus cooperates with the brake roller, and is actuatable by the cutting apparatus such that a rotational movement of the brake roller is able to be braked by the brake apparatus.

A bale wrapping apparatus includes a first wrapping material roll having a first wrapping material, and a first unrolling device. The first unrolling device in turn includes a loading device for loading the first unrolling device with the first wrapping material roll. The loading device is mounted pivotably about a pivot axis and is pivotable between a loading setting and an operating setting. The loading device has a pressure roller, wherein the pivot axis is arranged parallel to the rotational axis of the pressure roller. In the operating setting, the loading device, by means of the pressure roller, acts on the first wrapping material roll such that the first wrapping material roll can be subjected by the loading device, by means of the pressure roller, to a contact pressure force.

A bale wrapping device for a round baler includes a drive roller by which a wrapping material is able to be unrolled from a wrapping material roller. The drive roller is connected to a drive and brake apparatus. The drive and brake apparatus is connected to a brake belt which is able to be tensioned in a variable manner. The bale wrapping device further comprises a tensioning lever apparatus and the brake belt is connected to the tensioning lever apparatus. The pre-tensioning of the brake belt is adjustable by means of the tensioning lever apparatus between at least three different pre-tensionings.

Wrap material supply systems for delivering wrap material from a wrap material roll for application around crop bales include a baler housing containing a baling chamber, a drive roll rotatably mounted to the baler housing, and a pivoting frame coupled to the baler housing at a first pivot point. A feed roll is rotatably mounted to the pivoting frame and positioned to engage the wrap material roll. The wrap material supply system further includes a drive belt, which, when tensioned, transmits rotation from the drive roll to the feed roll. An actuator is controllable to rotate the pivoting frame about the first pivot point to move the feed roll relative to the drive roll, tension the drive belt, and initiate feeding of the wrap material from the wrap material roll into the baling chamber.

A bale wrap mechanism for use with a roll of wrap material, the bale wrap mechanism including a frame including a wrap chute formed from one or more perimeter walls, where the wrap chute defines a wrap axis extending longitudinally therethrough, and where the one or more perimeter walls at least partially define a passageway, a wrap arm coupled to the frame, the wrap arm having a mounting point movable with respect to the frame, and a shaft coupled to the mounting point and configured to support the roll of wrap material thereon, where the shaft is configured to travel along a wrap path during a wrapping process, where the wrap path surrounds the passageway, and where the wrap path is non-circular in shape.

A system for wrapping a material in a baler includes a feed element for feeding the material through a feed path. A drive element intermittently drives the feed element. A linking element couples the drive element with the feed element. A tensioning lever operates to vary tension on the linking element to intermittently drive or not drive the feed element. A knife mechanism operates to intersect the feed path to cut the material. An actuator is engageable with the tensioning lever and with the knife mechanism. The actuator operates to move the tensioning lever and the knife mechanism independent of one another.
