Patented in the German Empire on February 4, 1911.

So far, it has not been possible to use horizontal or approximately horizontal baling channels with pistons moving back and forth, trickling or short grit, such as chaff, torn straw, hay, flax straw, wood wool or the like, in bales evenly or sufficiently evenly dense everywhere press, because the material introduced into the baling channel α falls in this immediately to the ground and there, like the schematic

ίο Fig. ι shows, forms a flat heap g, which, in particular in the case of short-fiber convex goods, is pushed forward by the piston d and pressed against the bale f ¹ near the bottom a ¹ . The bales produced in this way show in their lower layers facing the channel floor a considerably greater density than in the upper layers, so that they cannot be bound at all or only poorly and usually unfold after leaving the baling channel.

The subject of the invention is a

Device that ensures the baling of bales with a sufficiently uniform density.

According to the invention, a rake, a perforated or uninterrupted plate o Another part set in such a movement context that this rake ■ or plate body on the return stroke of the plunger lowers through steep points with its lower edge into the shaft and lets the material collapse, on the other hand, during the forward (press) stroke, it rises like a flap, whereby it ^{pushes the part g 1 of} the pile g, which is designated with hatching in FIG. 1, in front of it and drives it against the upper face of the ball /, that is to say in the space marked by cross-hatching. In this the material is then firmly pressed by the plunger d immediately following the flap c. This rake or plate body thus also feeds part of the pressed material to the uppermost layers of the bale, regardless of the piston pressure, which ensures a considerably more uniform pressing than in the case of presses without the new device.

In Fig. 2 is an embodiment of the invention on a known baler, such as they are used for pressing hay, straw or the like, shown in side view.

A plate c (or a sieve, a rake or the like) is suspended from an immovable axis of rotation b above the compression channel α in such a way that it rises steeply during the return stroke of the compression piston d due to the action of weight or spring and enters the inlet shaft β for can reduce the compression channel α , as illustrated in the drawing. In this position, the plate c does not prevent the material to be pressed from falling in, so that it can fill the bottom a ^{1 of} the pressing channel between plate c and the face f of the ball. During its forward stroke, the piston d hits, for example, with its edge d ¹ against the plate c and rotates it upwards in the direction of the arrow as it continues its movement, the lower plate edge c ¹ describing the path χ. Here, the material lying on the channel bottom a ¹ is taken along for the most part and during

of the way χ while constantly approaching the upper part of the ball face, rain-trickled down over the edge c ^l . The consequence of this is that the ^{plunger immediately following the plate edge c 1} also finds good in the uppermost channel layers, which it immediately presses onto the face f of the ball. The same play begins again with the next return stroke of the piston. xo Instead of directly, the rake or the plate can also be controlled indirectly from the plunger or some other part related to movement, for example by means of cranks and handlebars. The axis of rotation b can also be arranged on the reciprocating plunger d and the pivoting of the rake or the plate c can be effected by fixed control stops or by means of links that hold a rake or plate point outside the axis of rotation b. It is useful to make the axis-δ with the rake or the flap, or both 'against each other, adjustable in such a way that the effective working edge c ¹ can be relocated with consideration that soon heavily, now sluggishly trickling material is to be processed . The invention can be used with the same success in other types of presses and in others Use short-fiber pressed material. Instead of the oscillating movement of the rake or of the plate c , a parallel displacement, or both at the same time, can occur.
