Abstract: An apparatus for wrapping net about bales formed in the baling chamber of a large round baler is arranged such that the net material supply roll is pressed directly against the driven wrap material feed roll by a pressure roll carried by a pair of transversely spaced lower arm portions of a lower arm section of a vertically swingable pressure arm assembly that also includes a separate, upper arm section. The force pressing the pressure roll against the supply roll originates with gas springs coupled to a linkage that is in turn coupled to transversely spaced upper arm portions of the upper arm section, these arm portions carrying respective force transfer rollers that engage respective intermediate sections of the lower arm portions. Associated with each lower arm portion is an inverted L-shaped bracket having a short leg pivotally mounted between the axis of the pressure roller and one end of a guide link which cooperates with the short bracket leg and the lower arm portion to form a four-bar linkage which acts to properly position retainer rolls, respectively mounted to the end of the long leg of each of the inverted L-shaped brackets, adjacent the periphery of the supply roll so as to prevent the supply roll from moving away from its desired location on the drive wrap material feed roll. The lower pair of arm portions are shaped for cradling a new roll of wrapping material when lowered to a loading position from which they may be raised to move the supply roll in engagement with the driven net feed roll. A guide structure is provided which cooperates with bale forming belts for conveying the wrapping material, once fed through the feed rolls, beneath the bale discharge gate and through the inlet of the baling chamber.

Abstract: A large round baler includes a net wrapping device mounted to the rear and bottom of the discharge gate of the baler. A spare roll of net material is stored above an active roll of net material which rests upon and is caused to be rotated by the upper roll of a pair of net material feed rolls. The rolls of material are wider than the baling chamber of the baler and net spreader rolls, including both raised spirals and spiral grooves, are provided along the net feed path so that the net is at its full width when it arrives at the inlet to the bale chamber which is located at a lower bale-forming belt support roll extending between opposite sidewalls of the gate at the lower front of the gate. A pair of guide plates are mounted to the insides of the bale chamber sidewalls and extend about an upper portion of the circumference of a net spreader rolls located at the opposite ends of the belt support roll. These guide plates are shaped and positioned such that they perform the functions of creating a space between the bale end and the side wall for receiving marginal portions of the net, defining together with the side walls, a channel which leads from the net spreader rolls to the space created for receiving the net, rounding the end edges of the bale for better reception of the marginal portions of the net and deflecting crop material away from the spirals of the net spreader rolls so as to prevent them from wrapping with crop which would interfere with the feeding of the marginal portions of the net to be placed over the edges or corners at the opposite ends of the bale. First and second alternate embodiments respectively have only the recess or the entire shape of inner surfaces of the guide plates formed into the sidewalls. In the latter case, openings are provided in the sidewalls adjacent the trailing part of the formed shape, as considered relative to the direction of rotation of a bale engaging the formed shape.

Abstract: A large round baler is equipped with a wrapping mechanism for applying a web of plastic material to a bale located in the bale-forming chamber. The wrapping mechanism includes a housing including a cover mounted to the rear of the discharge gate of the baler for pivoting vertically, about a first horizontal transverse axis at an upper forward location of the cover, between a lowered closed position, wherein it encloses a roll of wrap material resting on a pair of roll end supports, and a raised position permitting access to the roll end supports. A pair of gas springs are coupled between opposite side walls of the cover and spaced apart crank arms of a load member which is vertically pivotally supported from the gate for swinging about a second horizontal transverse axis located slightly below and rearwardly of the first axis. The disposition of the gas springs relative to the first and second axes is such that the springs act to maintain a load bar of the load member urged into contact with a roll of wrap material supported on the roll end supports when the cover is in its closed position and acts to pivot the load member so as to dispose the load bar thereof in a raised inoperative position in response to the cover being raised to its open position, the springs also acting to maintain the cover in its raised position.

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 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. A wrap material loading arm is vertically pivotally mounted to the support walls at locations adjacent the rear end of the bottom wall, the arm being shaped so as to be able to receive and cradle a supply roll in a relatively low position for ease in loading and for having a length of material pulled therefrom and placed around the forward part of a spreader roll of the material feed mechanism, when the arm is in a lowered roll-receiving position, and so as to deposit the cradled roll onto the bottom wall when the arm is lifted to a raised position.

Abstract: A system and method for controlling a wrapping process of a round bale is disclosed. The round bale rotates in a bale chamber of a round baler with elastic wrapping material being removed from a supply roller using a tensioning device and guided during the wrapping process by at least one guide roller. The round bale is wrapped with the wrapping material pretensioned by the tensioning device with an adjustable wrapping tension predetermined by the control unit. A sensor assembly may sense the actual value for a force resulting from the wrapping tension, which is compared with a target value for the force resulting from the wrapping tension, which is determined during the performance of at least one preceding wrapping operation and specific to the wrapping material. The control unit controls the tensioning device depending on the deviation determined by the comparison of the actual value and the target value.
