A method of controlling a wrap system of a round baler includes determining a current characteristic of a supply roll of wrap material related to a current weight of the supply roll, and controlling rotation of a pair of spool rollers based on the current characteristic of the supply roll. As the current characteristic indicates a decrease in weight, the rotation of the pair of spool rollers is controlled to achieve a desired acceleration rate of the spool rollers, such that a leading edge of the wrap material is ejected from a nip formed between the pair of spool rollers at an ejection trajectory that is within an allowable angular range relative to a tangent of the nip, so that the leading edge of the wrap material passes through an access and into a baling chamber of the round baler.

The present disclosure refers to a method for operating a round baler. The method comprises providing a nonstop baler type machine; controlling a feeding mechanism for feeding of crop into a prechamber and a main bale forming chamber by a control system of the baler; in a feeding operation, feeding the crop through a first feeding channel into the prechamber; and switching the feeding operation by the control system, thereby, stopping feeding the crop into the prechamber and starting feeding the crop through a second feeding channel into a main bale forming chamber of the baler. The control system is configured to switch the feeding operation in response to a binding material parameter reaching a predetermined parameter value, the binding material provided for wrapping a bale formed in the main bale forming chamber. Furthermore, a round baler is disclosed.

A supply apparatus for supplying wrapping material to a wrapper inlet of a baling chamber, in which a bale is to be wrapped. A reservoir supplies the wrapping material to an upper driven roller forming a lower part of the wrapper inlet. The wrapping material is guided to the wrapper inlet from above the wrapper inlet. A displaceable supply unit is located between the reservoir and the upper driven roller, the supply unit being moveable between a baling position and a wrapping position about a pivot axis located above the wrapper inlet. A free end of the wrapping material outside of the baling chamber is protected by the displaceable supply unit from air turbulence during operation of the baling apparatus.

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.

A gathering apparatus for selectively bringing together edges or sides of a film for wrapping around a bale includes a pair of gathering elements which cooperate with a respective edge of the film and which are movable by a drive. The drive is actuated by a motor and a reduction gear. The gathering elements are moved relative to the film in a lateral direction between an out-of-operation position and an operating position, in order to gather the film as required. A holding apparatus serves the gathering elements in the operating position.

A binding material storage apparatus including a rotary magazine for storage of binding material rolls, rotationally supported about a horizontal axis between two side elements. A magazine may be rotated between a number of discrete positions including a dispense position, each suitable for storage of a roll of binding material. The magazine includes first and second end plates between which support elements extend, one support for each discrete position, each of the supports mounted for free rotation within the magazine. At each discrete position a spindle is mounted for free rotation within the second end plate. An electrically controlled braking gear is supported on the second side. Each spindle is connected to an associated support and an associated first gear. The electrically controlled braking gear engages the first gear in the dispense position to control the speed of rotation of the support element in said position.

In a method for providing a bale of crop material that is only partially wrapped in a film, a bale of crop material is wrapped in a film with an automatic bale wrapping apparatus. Subsequently the film is provided with a plurality of perforations, and it is ensured that the perforations are present/positioned in an upper half of the bale. This ensures that there is good moisture control of the bale, with moist air able to escape, while stopping ingress of rain water. The bales are mostly dry hay or the like, and favourable perforations are radial slits. There is also provided a system for providing such bales with position controlled perforations.

Systems and methods are provided for controlling operation of one or more controllable components of an agricultural baler. Using a moisture level of material collected by the agricultural baler a baling strategy including an indication of a wrapping material for a formed bale is determined. Methods include controlling one or more operational components associated with the baler in dependence on the determined baling strategy to control the wrapping process in accordance with the determined baling strategy.

One or more information maps are obtained by an agricultural work machine. The one or more information maps map one or more agricultural characteristic values at different geographic locations of a field. An in-situ sensor on the agricultural work machine senses an agricultural characteristic as the agricultural work machine moves through the field. A predictive map generator generates a predictive map that predicts a predictive agricultural characteristic at different locations in the field based on a relationship between the values in the one or more information maps and the agricultural characteristic sensed by the in-situ sensor. The predictive map can be output and used in automated machine control.

An agricultural baler includes: a frame; a bale chamber coupled with the frame; and a control system including: at least one sensor coupled with the frame, positioned circumferentially relative to the bale chamber, and configured for sensing an operative parameter of a crop material in the bale chamber.
