A wrapping arrangement for an agricultural round baler includes a support frame and a wrapping mechanism including at least one wrap material feeder mounted on the support frame. The wrap material feeder includes a supply of wrap material. At least one wrap material clamp and cutting device is operably mounted to the wrap material feeder, and a clamp mechanism is mounted proximate to the wrap material clamp and cutting device. The clamp mechanism is adapted to clamp a free end of the wrap material by a biasing clamping force for pre-positioning the wrap material for functional operation with the wrapping mechanism.

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.

The present disclosure relates to a method for operating a round baler. The method comprises providing a nonstop baler type machine; feeding of crop into a prechamber and a main bale forming chamber; and providing, by a binding unit, a binding material to the main bale forming chamber for wrapping a bale formed in the main bale forming chamber, comprising, in a first mode of operation, providing a stretching apparatus in contact with the binding material, thereby, applying a compressive force to the binding material for stretching the binding material; and in a second mode of operation, providing the stretching apparatus free of contact with the binding material. Furthermore, a round baler is disclosed.

A constant tension mechanism of tying net for roll bales, that allows varying the stretching tension of the material in accordance with different diameters and thus provide a tying tension that allows keeping the geometry of the roll bale throughout time.

The present disclosure relates to a round baler (10) including a baling chamber (12) for forming a bale (26) and a first wrapping mechanism (32) mounted to the baling chamber (12). The first wrapping mechanism (32) includes a feed system that feeds the wrap material (30a) into the baling chamber (12). The round baler (10) further comprises a second wrapping mechanism (34) mounted to the baling chamber (12) which includes a feed system that feeds the wrap material (30b) into the baling chamber (12). Further, the round baler (10) includes an inlet (40) wherein wrap material (30a) from the first wrapping mechanism (32) and wrap material (30b) from the second wrapping mechanism (34) enter the baling chamber (12). The first wrapping mechanism (32) and second wrapping mechanism (34) are configured to be operated independently.

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.

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.

The invention relates to a round baler (1), having a pressing apparatus (9) for pressing agricultural crops into a bale (50) in a pressing chamber (13), and a binding unit (20), having a binding housing (21), a plurality of roll receptacles (22, 26) which are at least partially arranged in the binding housing (21) and which are each intended to rotatably receive a binding material roll (42, 43), a feed unit (30) by which binding material (44, 45) from a respective active roll receptacle (22, 26), which can be selected from the plurality of roll receptacles (22, 26), can be introduced in the direction of the pressing chamber (13), and a brake unit (35) configured to at least indirectly cooperate with a binding material roll (42, 43) so as to brake it. The number of components and the effort involved in changing between different binding materials are optimized.

A system and a method for moving wrap material in a baler are described. A motor can be secured to the baler and can be configured to rotate a wrap roller of the baler. The motor can be caused to rotate the wrap roller in a first direction, such that the wrap roller moves the wrap material towards a crop package contained by the baler. The motor can also be caused, during application of the wrap material to the crop package, to brake the wrap roller relative to the first roller direction or to rotate the wrap roller in a second direction that is opposite the first direction, in order to stretch the wrap material.

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.
