Abstract: An apparatus and method are provided for wrapping roll material around a round bale within a bale forming chamber of a round baler including a drive belt tensioner idler, a wrapping material brake and a wrapping material cut-off knife all disposed on a carriage that is articulated between a wrapping material feeding position and a cut-off/stop position. When baling is completed, a signal is provided for movement to the feeding position at which time the wrapping material is held taught to maintain bale compression. After sensor data are fed back to a controller to signal feeding has proceeded for the desired length of time and/or to deploy the desired length of wrapping material, the device articulates to the cut-off position to sever the wrapping material to allow completion of the bale wrapping procedure. A crop recycling mechanism can also be provided to re-feed stray crop material into the baling chamber.

Abstract: An agricultural baler for making cylindrical bales of crop material having a sledge assembly moveable between bale starting and full bale positions. The sledge assembly includes a plurality of rollers which cooperate with an apron to define a bale forming chamber. A dispensing mechanism is carried on the sledge assembly for dispensing sheet material, such as net or the like, into the bale forming chamber whereupon it is wrapped circumferentially around a cylindrical bale of crop material in the bale forming chamber. A net spreading system is associated with the dispensing mechanism to assure that the net being fed into the bale chamber via the dispensing mechanism is maintained at its nominal width which corresponds generally to the width of the chamber.

Abstract: The cutting mechanism has a stationary anvil and a movable knife that is swung across the path of travel of the taut, moving wrapper to deflect the wrapper into engagement with the anvil and accomplish severance. A tapered nose on the anvil fits into a slot along the length of the knife as the two components come together whereby the wrapper is stuffed by the nose of the anvil into the slot in a distorted condition, conforming to the shape of the nose and bending over a sharp edge along the slot. As the wrapper becomes gripped within the slot and bent over the cutting edge, it is severed cleanly from the roll and the severed length of the wrapper is delivered to the bale for completion of the wrapping cycle. The knife is in the nature of a tubular member with a slot in its peripheral wall so that the arcuate outer surface of the wall slidingly engages and keeps the wrapper out of contact with the sharp edge until the anvil enters the slot, thereby preventing premature snagging and severance of the wrapper by the sharp edge.

Abstract: A round baler includes a bale chamber in which, in use of the baler, a bale of crop material is formed; a source of bale wrapping material; bale wrapping control apparatus; and a knife operable under the control of the wrapping control means to cut the wrapping material. The bale wrapping control apparatus comprises a first set of worm and sector gears operable to drive the knife to a position ready for cutting the bale wrapping material and a second set of worm and sector gears operable to determine the length of wrapping material to be dispensed from the source of wrapping material for wrapping a given bale and then to initiate operation of the knife to effect cutting of the dispensed wrapping means from the source. Both of the worm gears are carried on a single master shaft which is rocked in one direction to activate the first set of gears and in the opposite direction to activate the second set of gears.

Abstract: A mechanism for enveloping a large round bale with a surface wrap material such as plastic sheet or net includes a housing for holding a supply roll of the wrap material. The mechanism and, hence, the housing is mounted on the rear of a bale discharge gate. The housing includes a front wall, defined by an upright panel secured across the rear of the gate, and a bottom wall sloped upwardly and rearwardly relative to the front wall. The bottom wall and front wall converge toward a wrap material passage defined between a forward edge of the bottom wall and the front wall. The bottom wall is curved convexly upwardly between front and rear ends thereof, with the curvature and slope of the bottom wall being chosen such that a roll of wrap material resting on the bottom wall will become increasingly wedged against the front and bottom walls as the material is used and the weight and diameter of the roll decreases with the result that the braking force imposed on the roll will remain substantially constant no matter what the weight or size of the remaining roll.

Abstract: A mechanism for enveloping a large round bale with a wrap material such as plastic sheet or net includes a housing for holding a supply roll of such material. The mechanism is mounted to the rear of a bale discharge gate. The housing is substantially enclosed except for an open front which is closed by a panel carried by the gate. The housing is vertically pivotally mounted for swinging away from the gate to a lowered position disposing its open front so that it faces rearwardly for reception of a supply roll of wrap material. A spring-loaded U-shaped structure is provided on the housing for biasing the material toward a lower front corner defined at the juncture of a plane containing a bottom wall of the housing and the panel.

Abstract: A bale wrapping mechanism for wrapping a large round bale with a wrap material such as plastic sheet material or net, is mounted to the rear of a bale discharge gate. Drive rolls are located rearwardly of the gate and are selectively drivable for dispensing wrap material onto the rear end of a guide pan extending beneath and engaged with a portion of bale-forming belts extending between lower rear and lower front belt support rolls carried by the discharge gate. A guide finger assembly is secured to the front of the pan and includes a plurality of fingers located in gaps between the bale-forming belts and including forward end portions curved arcuately about the lower front belt support roll for directing wrap material about the roll and into a pinch point defined between the belts and a bale desired to be wrapped by the material.

Abstract: A wrapping assembly includes: a material roll configured to hold a roll of wrapping material; a duckbill assembly including a duckbill carrying a duckbill roll and configured to draw material from a roll of wrapping material held by the material roll; a duckbill actuator coupled to the duckbill to move the duckbill between an insert position and a home position; a variable brake associated with the material roll and configured to apply a variable braking force to the material roll; and a controller operatively coupled to the duckbill actuator and the brake. The controller is configured to: determine an averaged electric current draw of the duckbill actuator during a sampling period is below a defined value and responsively output a brake increase signal so the brake increases applied braking force to the material roll by a defined amount.

Abstract: A bale wrapping device is described for a round baler. The bale wrapping device may include a supply reel for the wrapping material and a pressing device wherein the pressing device in an engagement position stands in engagement with the supply reel and for a standby position can be pivoted away from the supply reel, wherein the pressing device is connected at a contact point positioned on the pressing device to power means which generate via the contact point a controlling torque which acts on the pressing device. In order to facilitate the replacement of the supply reel and more particularly the pivoting of the pressing device out from an engagement position into a standby position, an adjusting means may be provided through which the contact point can be shifted and thus the controlling torque can be altered.
