Abstract: A channel baler including a pressure channel, a plunger located in the pressure channel, a thrust crank drive for reciprocating the plunger in the pressure channel, and an element which provides for elastic yielding of at least one element of a pressure system including the pressure channel, the plunger and the thrust crank drive, in an axial direction by a path corresponding approximately to a thickness of a compressed bale upon a plunger power exceeding a predetermined value.

Abstract: A baler for forming rectangular bales from harvested crop and including a baling channel having an inlet opening, a pressure piston reciprocating in the baling channel and periodically closing and opening the inlet opening, a continuously driven rake conveyor for delivering the harvested crop through the inlet opening of the baling channel synchronously with reciprocating movement of the pressure piston, a switch mechanism for periodically turning off the rake conveyor, and a brake for retraining the rake conveyor for at least one delivery period in its undelivering position outside of a delivery channel, and a control unit for turning on the rake conveyor synchronously with the reciprocating movement of the pressure piston.

Abstract: A round baler for fibrous agricultural material including compression and delivery elements, a main drive for driving the same, a wrapping apparatus, and at least one load sensor provided in the drive line for the compression elements for generating a control signal for actuation of the wrapping apparatus and/or turning off of the delivery elements.

Abstract: A roll baler for agricultural harvest products having a stem and including an approximately cylindrical pressing space and a plurality of press rolls arranged along a circumference of the pressing space close to each other, with each press roll having a plurality of longitudinal ribs uniformly distributed along a periphery of the press roll at a predetermined circumferential distance from each other, and with the predetermined distance being so selected that no two roll ribs lie in two mutually perpendicular longitudinal central planes of the press roll.

Abstract: A device for stacking rectangular bales of stalky material connected directly at the compression duct of a baling press consists of a horizontal platform supported to be displaceable in vertical guides and capable of being lowered from an uppermost position in several stages corresponding to the height of a bale to be stacked. The lowering stages are determined by mechanical pawls and the lowering movement is triggered automatically by a bale when reaching its end position via a bale sensing device. In order that entwining of material at the point of separation between adjoining bales of stalky material does not disturb the lowering movement, a forward bale is forcefully separated from a succeeding bale before lowering by additional forward feed elements controlled by bale sensing devices.
