Abstract: A swiveling piston press, in particular for compacting waste cardboard, including an arcuate compression channel in which a compression piston is supported for pivotal movement between two positions by a hydraulic piston-cylinder unit with the piston press being designed in such a way that the piston rod is loaded in tension during the compression stroke movements of the compression piston, and in its extended position, forms an acute angle with the line connecting the pivot axis of the compression piston with the connection point of the compression piston with the piston rod.

Abstract: A round baling press for agricultural stalk grains is disclosed which comprises revolving pressing elements wherein the revolving pressing elements include at least one of rollers, conveyors belts, conveyor bar chains and similar items, and further wherein the revolving pressing elements bound a pressing space. The revolving pressing elements are driven on their side facing the pressing space in a region of a commodity inlet aperture so as to revolve from a bottom to a top. The round baling press also comprises a revolving conveyor arrangement, wherein the revolving conveyor arrangement is driven in a same peripheral direction as the pressing elements. The revolving conveyor arrangement is disposed between a pickup and the commodity inlet aperture. The conveyor arrangement further comprises a conveyor roller having rigid prongs which are disposed directly upstream of the commodity inlet aperture and above a supply channel base so as to be rotatably fixed in a supply channel.

Abstract: In a reciprocating piston press where a compressing piston operates in a nonuniform manner, the piston cooperates with conveyor prongs which move material into the path of the piston. The conveyor prongs are guided by a crank and rocker linkage mechanism by way of elliptical gear wheels for movement around a kidney-shaped orbit. The prongs perform a more rapid motion in the region of a fill opening for charging material into a compaction channel containing the compressing piston. The reciprocating piston press is, in particular, employed for compacting cardboard waste in combination with a feeder space which opens into the compaction channel for charging cardboard waste into the channel. The feeder space and piston press are located in a stationary housing.

Abstract: The invention relates to a method and to a device for producing highly compressed cylindrical bales from loose stalk material, such as hay or straw, which is picked up continuously and is compressed to form a rotating compressed roll which flows continuously in an axial direction. Individual compressed roll sections (bales) are successively cut off from the front end of the compressed roll. For producing dimensionally stable bales of varying length, the compressed roll, which is still subject to radial pressure, is bound automatically by a binder during its axially feeding and before a bale is cut off. The binder is delivered under tension and utilizes the rotation and feed of the compression roll.

Abstract: A method and apparatus for helically-shaped binding of round bales consisting of harvested agricultural crops using two cord strands, which respectively wrap around somewhat more than half of the bale for shortening the binding period, one cord strand being cut off to begin with and the other cord strand being wrapped several times around the previously cut-off strand prior to being cut-off itself. In order to avoid a mutual loosening of the severed cord ends after severing the cord strands upon termination of the binding process.

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.

Abstract: Apparatus for forming roll bales of agricultural harvest material operating to helically tie the roll bales with twine is provided with a twine guide member moving along a front intake aperture of the baler and automatically controlled by a ratchet and pawl mechanism. The guide member is biased toward a lateral rest position by a spring. An actuating line is attached to the guide member to enable the guide member to be moved to an opposite lateral start position against the force of the spring. The actuating line is wound around a pulley of the ratchet and pawl mechanism. The ratchet and pawl mechanism includes a releasing disc which is driven by the twine itself during a tying operation and which carries a lifting cam which alternately disengages a pair of pawls of the ratchet and pawl mechanism.

Abstract: In an agricultural pick-up baler a pick-up device loads harvested agricultural material into a supply passage connected to the inlet opening into a compressing channel, said inlet opening being located in the bottom of said compressing channel. A pressing ram is reciprocated back and forth in the compressing channel by at least one connecting rod and compacts the material introduced into the compressing channel. A conveying device fixed to the connecting rods extends into the supply passage and moves the agricultural material from the pick-up device through the supply passage toward the inlet of the compressing channel. A packing device located in the supply passage moves the agricultural material received from the conveying device through the inlet into the compressing channel. The path of travel of the conveying device within the supply passage passes through the path of travel of the packing device.
