Abstract: An actuating mechanism for the functional elements in a round baler for agricultural crops includes a tensioning arm which is provided with guide rollers and a pivotal arm and which is pivoted on the frame of the baler via a hydraulic cylinder. The hydraulic cylinder is arranged between the pivotal arm and a first arm of a bell crank, which is pivotally mounted on the tailgate. A second arm of the bell crank is selectively engageable with the front part of the housing.

Abstract: A combined large round baler and whole bale wrapping apparatus includes a wheeled chassis carrying and extending between the baler and the wrapping apparatus and including tandem wheels carried at opposite ends of walking beams. A lower region of the baler is secured to the front of the chassis. First and second braces are fixed to, and diverge upwardly from, a fore-and-aft middle location of the chassis respectively to the hinge joint between the front and rear sections of the baler and a wrapping arm assembly. A tie-bar extends between the two braces. The wrapping apparatus includes a wrapping table mounted to the chassis for fore-and-aft movement between a receiving position, wherein it is disposed for receiving a bale formed by the baler, and a wrapping position, wherein it is located centrally below the wrapping arm.

Abstract: In a round baler for agricultural crops including a supply station for feeding-out a strip-like covering material for the fully wound round bale and a cutting device for severing the covering material, simple provision is desirable for pulling the new leading-edge of the strip of covering material away from the knife-edge after the cutting process. Drive shafts of the advancing roller and a detainable ratchet wheel are mutually coupled in rotatable manner by a resilient hub-shaft connection. The hub-shaft connection is constructed such that, when the ratchet wheel is detained, the advancing roller can still rotate through a small angle and thereby deform resilient drive elements in order to produce an extremely high tension in the strip. The restoring forces so created turn the advancing roller in a direction opposite to the direction of movement of the strip as soon as the strip is severed. The leading-edge of the strip is thereby pulled away from the knife-edge.

Abstract: A round baler has a guiding device for guiding baling material around the press- or idler rolls. The guiding device includes an elastic piece of material and a generally inelastic but form-flexible piece of material; so that on the one hand a high elasticity of the guiding device is achieved and on the other hand high endurance of the form-flexible material is achieved.

Abstract: A round baling press for baling harvested crops has a device for storing a roll of netting web for binding bales. Stones and other foreign bodies thrown into the housing of the baling press can lead to breakdowns and damage to the mechanism for feeding netting web into the baling press. A flexible and plastic web, preferably made of transparent material, is used as an inexpensive and simple housing cover to prevent stones and foreign bodies from entering the housing of the baling press.

Abstract: A method of producing a roller casing of a roller has providing a plane casing blank, forming an outer helical raised structure on the plane casing blank, bending the plane casing blank with the raised structure to form a cylindrical roller casing, and connecting with one another abutting regions of the cylindrical roller casing.

Abstract: An agricultural baler has a pickup elements, a conveyor transporting a harvested product stream picked up from a field by the pickup element, a baling chamber for baling the harvested product, a transferring element for transporting the harvested product from the conveyor to the baling chamber, the transferring element including a cylinder and a plurality of disks arranged on the cylinder, and a plurality of strippers extending into spaces between the disks for preventing winding of the harvested product on the disks, the strippers being formed as sensing brackets for sensing deviation of the strippers. Also a deviation of knife blades arranged in spaces between the neighboring disks and offset relative to the strippers can be evaluated as well.

Abstract: A round baler includes an expansible, upwardly converging wedge shaped bale chamber having an opening at its bottom and being formed in part by first and second belt runs that respectively converge upwardly from first and second belt support rolls respectively located at the front and rear of the inlet opening. Expansion of the baling chamber works against a downwardly biased tensioning frame pivotally mounted to opposite side walls, the first and second belt runs extending between a fixed and a pivotal roll carried by the frame with the pivotal roll being controlled to move closer to the fixed roll as the tensioning frame is forced upwardly by a growing bale. A fingered rake structure bridges the gap between the fixed and pivotal rolls to keep crop material from exiting the chamber.

Abstract: A round baler has a baling chamber formed in part by a plurality of belts engaged with a plurality of rolls extending between opposite side walls of the baler, the rolls and belts being located such as to define an enclosed zone next to the baling chamber. The belt arrangement is so designed that in conjunction with two rolls between which some of the belts extend directly there is used a roll arrangement which includes at least two axially aligned rolls offset from the other two rolls and being engaged by the remaining belts so that gaps are created between offset belts extending about the offset rolls and the non-offset belts extending directly between the first mentioned two rolls. These gaps serve to permit pieces of the material being baled to escape from the area otherwise enclosed by the belts.

Abstract: The baling chamber of one type of round baler is defined by belts which are trained over rolls connected to a drive. Stones can enter the nip formed between the belts and some of the rolls, e.g., a lower front belt driving roll, and thereby cause poor tracking of the belts. To reduce the problem, a shield device is snap-fit mounted on the roll. The device includes a nip bridging plate an upright portion of which abuts the belt run advancing to the nip and a downwardly sloping lower portion of which bridges the nip. Thus the device covers the nip preventing access to it by the stones, and stones which fall upon it slide down the sloping portion of the plate eventually to find their way harmlessly to the ground.

Abstract: A baling maching includes a variable volume baling chamber with which there is associated a hydraulic tension cylinder containing fluid in its rod end for resisting expansion of the baling chamber. A high pressure relief valve is connected in circuit between the opposite ends of the cylinder for permitting fluid transfer between the ends in accordance with the pressure setting of the valve. A low pressure relief valve is connected in circuit between the opposite ends of the tension cylinder so as to be in parallel with the high pressure relief valve.

Abstract: A large round baler having an expansible bale chamber has tension cylinders associated with the chamber for strongly resisting expansion thereof so as to produce dense bales when a bypass valve located in a bypass line interconnecting rod and piston ends of the tension cylinders is positioned for preventing flow through the valve thereby forcing the flow to go through a variable high pressure relief valve located in another bypass line, the bypass valve being selectively shiftable to another position for permitting free flow therethrough when it is desired to produce a soft bale. The baler also includes gate cylinders for opening and closing the discharge gate of the baler.
