DETAILED DESCRIPTION OF THE INVENTION

[0025] The present invention relates to an agricultural mesh for baling (1) comprising a plurality of columns of chains or pillars (3) interconnected with each other by means of the wefts (2) and wherein each column of chain or pillar (3) comprises a plurality of meshes (4).

[0026] For a better understanding of the present invention, it should be understood that the first column of chain or pillar (3a) relates to a first column of the agricultural mesh for baling (1). The second column of chain or pillar (3b) relates to the column of chain or pillar just after the first column of chain or pillar (3a) of the agricultural mesh for baling (1). The third column of chain or pillar (3c) relates to the column of chain or pillar just after the second column of chain or pillar (3b) of the agricultural mesh for baling (1). This configuration is repeated several times along the length of the agricultural mesh for baling (1).

[0027] The agricultural mesh for baling (1) has a triangular configuration, resulting from the interlacing of the wefts (2) in a first column of chain or pillar (3a), passage through a second column of chain or pillar (3b), interlacing in a third column of chain or pillar (3c) and return to the first column of chain or pillar (3a) through the reverse longitudinal zigzag path with passage through the second column of chain or pillar (3b) and return to the first column of chain or pillar (3a), at intervals of six meshes (4), along the length of the agricultural mesh for baling (1).

[0028] Additionally, each weft (2) is initially interlaced in the columns of chains or pillars (3) at intervals of six meshes (4) along the length of the agricultural mesh for baling (1).

[0029] In addition, the weft (2) has a triangular shape resulting from the interlacing in the first column of chain or pillar (3a), passage through a second column of chain or pillar (3b), interlacing again in a third column of chain or pillar (3c) and return to the first column of chain or pillar (3a) through the reverse longitudinal zigzag path with passage through the second column of chain or pillar (3b), and return to the first column of chain or pillar (3a), at intervals of six meshes (4), along the length of the agricultural mesh for baling (1).

[0030] This process is repeated as many times as the sets of six meshes (4) existing along the length of the agricultural mesh for baling (1), resulting in a triangular configuration between the connection of weft (2) with each two columns of chains or pillars (3). This configuration takes the form of an equilateral triangle.

[0031] The columns of chains or pillars (3) that form the agricultural mesh for baling (1) have a distance between them enough to ensure the strength and cohesion of the agricultural mesh for baling (1) in the bales.

[0032] More particularly, the distance between columns of chains or pillars (3) that form the agricultural mesh for baling (1) is X, wherein X represents the minimum allowable distance between two columns of chains or pillars (3).

[0033] The minimum allowable distance between two columns of chains or pillars (3), X, can be defined as the ratio between the width of the roller of the agricultural mesh for baling (1) and the number of spacings between each two columns of chains or pillars (3) plus 1. Considering that the agricultural mesh for baling (1) has L columns of chains or pillars (3), we known that L corresponds to the number of spacings between two columns of chains or pillars (3) plus 1, referred to as R. To the number of spacings between two columns of chains or pillars (3) plus 1, R, correspond R spacings in the roller of the agricultural mesh for baling (1), due to the back-and-forth movement occurring in the winding phase of said agricultural mesh for baling (1).

[0034] In one embodiment, the distance between the columns of chains or pillars (3) that form the agricultural mesh for baling (1) is X.

[0035] In another embodiment of the present invention, the distance between columns of chains or pillars (3) that form the agricultural mesh for baling (1) is 2X, wherein 2X represents twice the minimum allowable distance between two columns of chains or pillars (3).

[0036] In the case where the distance between the columns of chains or pillars (3) that form the agricultural mesh for baling (1) is 2X, the distance between the columns of chains or pillars (3) is 100% higher when compared to the distance of columns of chains or pillars (3) in the case where the distance between the columns of chains or pillars (3) that form the agricultural mesh for baling (1), have a distance between them of X. In this latter case, although the distance between the columns of chains or pillars (3) is higher, it is ensured that the agricultural mesh for baling (1) remains intact and cohesive, without any breaking of the weft (2), which allows to produce even stronger bales, with a higher retention grade of the wrapped material.

[0037] The width of the agricultural mesh for baling (1) may have different values according to the type and dimensions of bale to be covered. The possible width values of the agricultural mesh for baling (1) are as follows: 50 cm, 66 cm, 80 cm, 90 cm, 99 cm, 100 cm, 105 cm, 123 cm, 125 cm, 130 cm, 163.5 cm, or 170 cm.

[0038] The materials that compose the agricultural mesh for baling (1) according to the present invention are selected from the following: high density polyethylene (homopolymer or metallocene), or polypropylene copolymers in a mass fraction up to 20%, or copolymers of polyethylene in a mass fraction up to 20%, or high-density polyethylene with polypropylene homopolymer in a mass fraction up to 20%.

EXAMPLES

Example 1

[0039] In one embodiment of the present invention, the agricultural mesh for baling (1) comprising columns of chains or pillars (3) spaced apart from each other in a distance X, wherein weft (2) is initially interlaced in the first column of chain or pillar (3a), interlaces in the third mesh (4) of the third column of chain or pillar (3c), interlaces again in the first column of chain or pillar (3a) in the reverse path, in a total distance of six meshes (4) in the first column of chain or pillar (3a). This process is repeated as many times as the sets of six meshes (4) existing along the length of the agricultural mesh for baling (1). Each column of chain or pillar (3) is formed of a yarn, and a bale with improved strength and cover is obtained.

Example 2

[0040] In a further embodiment of the present invention, the agricultural mesh for baling (1) comprising columns of chains or pillars (3) spaced apart from each other in a distance 2X, wherein the weft (2) is initially interlaced in the first column of chain or pillar (3a), interlaces in the second mesh (4) of the second column of chain or pillar (3b), interlacing again in the first column of chain or pillar (3a) in the reverse path, in a total distance of six meshes (4) in the first column of chain or pillar (3a). This process is repeated as many times as the sets of six meshes (4) existing along the length of the agricultural mesh for baling (1). Each column of chain or pillar (3) is formed by two yarns. Although the distance between the columns of chains or pillars (3) is the double, an even stronger bale with a higher degree of baled material is obtained, using the same amount of weft (2) as referred to in Example 1.
