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 system for controlling a braking mechanism for a supply roll with wrapping material for a round baler that passes through a first phase wherein, after detection of sufficient crop material in the baling chamber, wrapping material is brought up to the baling chamber and introduced into the baling chamber. The braking mechanism provides a higher braking force during the wrapping operation than the first phase. The wrapping operation is started on detection of movement in the wrapping material. This prevents the braking mechanism from being activated prematurely and leaves sufficient time to deactivate the braking mechanism after the wrapping operation.

A control system for an agricultural baler includes a controller configured to receive a bale wrap signal indicative of a type of a bale wrap. The controller is also configured to determine whether the bale wrap is segmented or continuous based on the type. Furthermore, the controller is configured to control a braking system to establish a tension force at a weakened section of the bale wrap sufficient to separate a first portion disposed about a bale from a second portion disposed about a shaft in response to determining the bale wrap is segmented and the weakened section is positioned between the shaft and the bale. In addition, the controller is configured to control a cutting system of the agricultural baler to cut the bale wrap in response to determining the bale wrap is continuous and a target section of the bale wrap is positioned at the cutting system.

An assembly is described for braking and indexing rotating components, including guide rollers of balers. A wheel is attached to a rotating component and is surrounded, at least in part, by a traction device. A tensioning assembly with a lost motion linkage is attached to the traction device and to a frame. A counterforce assembly is also attached to the traction device and to the frame. When a portion of the tensioning assembly is moved in a braking direction, the stop prevents further movement of the lost motion linkage to apply a tensioning force to the traction device. The tensioning force is resisted by the counterforce assembly to impose a braking force on the wheel and thereby brake the rotating component. Moving the portion of the tensioning assembly in a release direction moves the lost motion linkage away from the stop, thereby reducing the braking force on the wheel.

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 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 round baler having a baling chamber, a wrapping material reservoir, a feed apparatus having an actuator, the feed apparatus configured to convey a wrapping material from the wrapping material reservoir to the baling chamber, a cutting apparatus moveable between a retracted position allowing free movement of the wrapping material and an advanced position to cut the wrapping material, and a braking apparatus for applying a braking force on a roll of wrapping material installed in the wrapping material reservoir, and an actuator for controlling operation of the feed apparatus and the cutting apparatus. The round baler further comprises a tensioning element connecting the actuator to the braking apparatus to control a down force exerted on the roll of wrapping material and so control the tension in the wrapping material.

A baler implement includes a baler controller configured to determine an unstretched length of wrap material dispensed by a wrap system during a wrap cycle, and determine a circumference of a bale in a baling chamber. The baler controller may then determine a stretched length of the wrap material as applied onto the bale during the wrap cycle from the circumference of the bale and a number of wrap layers of the wrap material wrapped around the circumference of the bale. The baler controller may then compare the stretched length of the wrap material as applied onto the bale to the unstretched length of the wrap material dispensed by the wrap system during the wrap cycle to determine an applied wrap stretch factor. The applied wrap stretch factor may be communicated to an operator, or used to control the wrap system to achieve a desired wrap stretch.
