Description

[Detailed Description of the Invention] The present invention relates to a roll-shaped bale made of agricultural stalked material, in which a band-like material is wrapped around the outer periphery of the bale for fixing the shape of the bale. .

A roll-shaped bale of agricultural stalks, in which a strip of material fixing the shape of the bale is wound around the outer circumference of the bale, the strip of material being made of an elastic plastic sheet is known (Germany). Republic Patent Application Publication No. 2219976). The above-mentioned elastic plastic sheets can also have small perforations (German Published Patent Application No. 2705101). In a known roll-shaped bale in which a sheet is wrapped around the outer circumference of the bale, the mutually overlapping portions of the sheet are welded,
In the past, it was essential to fix with a glazing block or an adhesive. However, such fixing requires high costs.

Furthermore, the use of a material having a network structure as a band material has already been proposed. However, in this case, in order to secure the strip material wrapped around the outer circumference of the bale so that it does not loosen later without the use of additional fastening means, in practice it is necessary to wrap the strip material around the outer circumference of the bale at least twice or twice. Unless there are at least two or two and a half turns in this way, additional fixing means are required for the overlapping parts of the strip of material.

The object of the invention is to provide a roll-shaped bale of the type mentioned at the outset, which has a strip of material that is particularly simply constructed and can be easily wrapped around the bale and secured.

According to the present invention, this problem is solved by a roll-shaped bale made of a stalked material, in which a band-like material of a network structure is wound around the outer periphery of the bale to fix the shape of the bale, and has portions that are overlapped one above the other. In the case where the belt-shaped material is made of a substantially inelastic net in the circumferential direction of the bale, the length of the mutually overlapping portions of the net in the circumferential direction of the bail is 1/1/2 of the outer circumference of the bale. 2, and these mutually overlapping parts can be partially attached one above the other and through the mesh without additional fixing means such as welding, lacing, glazing or adhesives. This problem is solved by engaging and attaching to a pedicle that protrudes outward. It is particularly advantageous to design the mutually overlapping parts of the net in such a way that they produce sufficient adhesion for fixing the shape of the veil.

Advantageously, the mesh is made with a coarse mesh.

The use of netting as the strip of material wrapped around the outer circumference of the bale provides the following significant advantages: That is, the adhesion forces created between the mutually overlapping parts of the net itself, on the one hand, and between the net and the stalks, on the other hand, prevent the band-like shape of the outer circumference of the bale, which was hitherto considered indispensable. Any additional fixing means such as welding, strapping, glazing or adhesives to the material can be dispensed with altogether. Depending on the properties and structure of the netting used, the strips of material fixing the shape of the bale need only be partially overlapped to create sufficient adhesion. The overlap length is less than 1/2 of the veil circumference. After the net is wrapped around the bale, the shape of the rolled bale is fixed. This rolled bale will not loosen again even if it is left to rest for a relatively long period of time.

The invention will now be described with reference to the illustrated embodiment.

FIG. 1 is a schematic diagram of a conventional roll-type bale forming machine, a so-called roll baler. A large number of press rollers 6 forming bale forming chambers are arranged around the outer periphery of the roll bale forming machine. These press rollers 6 are driven to rotate, and wind and compress the stalked material supplied into the bale forming chamber into a roll shape. Reference numeral 2 indicates the rolled bale being formed. A storage roll 8 is rotatably supported on a shaft 9;
This axis 9 is arranged between two mutually parallel arms 7. The arm 7 with its axis 9 can be pivoted by means of a piston-cylinder unit 10 from the position shown in solid lines in FIG. 1 to the position shown in chain lines.

The net 1 is unwound from the storage roll 8. The net 1 is pulled out by both pull-out rollers 5. A braking force is applied to the storage roll 8 by means not shown. A length measuring device 3 is arranged in conjunction with or separately from the pull-off roller 5 (but close to the pull-off roller 5). A mesh cutting device 4 is also provided at the entrance of the mesh. The cutting takes place in relation to the length of the drawn-out mesh.

The mesh 1 is substantially inelastic in the longitudinal direction, that is to say in the circumferential direction, whereas it is elastic in the transverse direction of the mesh.

Portions 1a, 1 of the net 1 that are overlapped with each other
b are attached to each other. This adhesion state is
It is reinforced by stem material that projects radially outward through the mesh.

A strip-shaped net 1 wrapped around a storage roll 8
has predetermined tear points in the transverse direction of the net and across the entire width of the net for each predetermined longitudinal section. With such a predetermined set tear point,
The mesh cutting device 4 can be constructed as a tearing device. However, it is also possible to provide other types of cutting devices, for example conventional cutting devices or fusing devices.
