Abstract

At the pressing of animal fodder into a bale (1A, 1B, 1C, ...), which in conjunction with the pressing is provided with packaging film (10), applied generally transverse to an advancing direction at the pressing, the bale is divided into sub-bales within the packaging film (10).

The invention This is achieved according to the invention by dividing the bale into sub-bales within the cohesive member.

The cohesive member may generally be mesh, yarn or the like, but in practice it is common to use plastic film, usually stretch film, to achieve the desired ensilage.

As a first alternative, the longitudinal bale is cut into sub-bales in the press.

As a second alternative, sub-bales are formed in succession in the press. These sub-bales are provided with plastic film or not before the arrangement of the cohesive member is formed to form the bale.

A bale can thus be divided by means of one or more knives in the baler channel of the press, and a stretch film is applied under tension transversely to the longitudinal direction or direction of advance of the bale in successive turns when advancing the bales out of the bale channel and on a subsequent bale slide. As shown above, two or more smaller, wrapped or unwrapped bales from a smaller press can also be held together into a larger bale in this way.

The following advantages are achieved by: a) A cost-effective bale, consisting of two or more sub-bales, is obtained. b) The stretch film holds the different sub-bales together.

C) The transverse stretch film has begun the desired tight enclosure for ensilage. d) The transverse film facilitates the separate, final wrapping with plastic film. e) The edges of the bale become less "sharp". 10 15 20 25 30 35 051013 LI PASGAO Staffan B0dArbemg \ P \ 005 \ Bl \ lvcnlk Unn 05101Ldoc 3 f) Protruding straws will be bent down before the final wrapping with plastic film, which helps to achieve a faster and denser wrapping. g) The immediate containment is beneficial for the ensilage process. h) The stretch film will be torn off between the bales by the arrangement with the bale slide. i) By appropriate construction of the bale slide and the location and variation of layers of plastic film along the bales, the tearing process can be regulated to take place between every second or every third bale. It is thus possible to obtain a bale containing 2, 4, 6, sub-bales with a knife. With two knives can 3, 6, 9,. sub-bales are obtained.

Brief description of the drawings The invention will be described in more detail in the following with reference to the accompanying drawings, in which Fig. 1 is a very schematic side view, partly in section, of a baling device according to the invention and Fig. 2 is a corresponding end view of this device.

Description of a practical embodiment A baler device illustrated in the drawings is intended for pressing substantially parallelepiped bales 1A, 1B, 1C, the method and the device according to the invention can just as easily be used for substantially cylindrical bales.

A beam channel 2, preferably of metal material, has a rectangular cross section and is arranged in a chassis (not shown). This chassis can be wheeled and can be connected to a tractor. As a non-limiting example. of animal feed or silage, but the cross-sectional dimensions of the channel 2 can be 80x90 cm.

The beam channel 2 can, as indicated, be inclined downwards from an entrance spirit to the right of the drawing to an outlet spirit to the left of the drawing.

A piston 3 with an outer shape corresponding to the inner shape of the beam channel is arranged for reciprocating movements in 10 15 20 25 30 m ro ~ q m ~ o 051013 ml PASS !!!

The reciprocating movements can be achieved, for example, by means of a crank mechanism 4, as is well known to the person skilled in the art. The driving force for this mechanism can be obtained, for example, from the tractor's standard power take-off.

A transverse knife 5 is permanently attached in the vicinity of the entrance end of the beam channel 2. The knife 5 may have a cup-shaped and wavy cutting edge to the right in Fig. 1 to improve its cutting properties. In the illustrated case, the knife is arranged vertically, but it may also have another. which is advanced in and out of the beam channel 2 under the influence of the piston 3, orientation. The pressed bales 1A, 1B, 1C, will thus be cut longitudinally into two portions or sub-bales, as also illustrated in Fig. 2.

A rotatable packaging film ring 6 is arranged at the outlet end of the beam channel 2. It can be supported and rotated by two drive rollers 7 (for example hydraulically driven) and guided by a guide roller 8.

A roll or magazine 9 for packaging plastic film 10 can be supported by the ring 6 via a bracket 11. The plastic film 10 is preferably of the stretch type, and the film magazine 10 is in this case provided with brake and stretch rollers 12 and 13 in a stretch assembly.

Parts 6-13 can together be defined as a wrapping unit.

By rotating the ring 6, packaging film 10 can be laid overlapping in a stretched state around the bales 1A, 1B, 1C, ..., which are carried out of the beam channel 2. 10 t fi PO NJ 0 \ 01 \ O 051513 LI PASSAO Sultan Sbdsxbezgwwtišwlhvunnk bvem Oßlllltdoc 5 IC can - after being wrapped - continue on a bale slide 14, motion-facilitating rollers or not. which may be provided with wrapped bales 1C may be removed or separated by gravity from the bale row leaving the bale slide 14, and the stretch film will thereby rupture between the bales.
