Abstract: A round baler has a bale chamber, a movable flap for delivering a bale, a wrapping material dispenser for supplying wrapping material for wrapping a finished bale in the bale chamber, a knife movable from a ready position into a final position to separate a continuous web of the wrapping material between the dispenser and the bale chamber and which, coupled to an actuation of the flap, is returnable to the ready position, separate actuating elements assigned to the knife and to the flap, a common drive energy source, a line connecting actuating elements to the common drive energy source, and an interrupter located on the line, wherein the drive energy source and the actuating element of the knife are located on one side of the interrupter, while the actuating element for the flap is located on another side of the interrupter.

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: 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.
