Definitions
- the invention relates to a binder for tying cylindrical bales, as is required, for example, for round bales from agricultural stalks or for garbage bales.
- Cylindrical bales were previously tied in a conventional manner using twine.
- the twine was wrapped several times around the cylindrical bale and partly additionally knotted. Because the tying process took a very long time, people were looking for alternatives to the known thread tying.
- Films and nets were then introduced as newer binders. Examples of this binding technique can be found in the patents DE 27 05 101, DE 25 12 381, DE 32 27 160 and EP 0 126 278. While on the one hand the films tear easily and are not sufficiently vapor-permeable to prevent rotting of moist material in the cylindrical bale To avoid, the knitted nets suffer from the disadvantage that they are very expensive to manufacture.
- the new binder should, if possible existing binding devices of balers can be processed in order to avoid conversion work on the balers.
- the object is achieved by using a nonwoven as a binder.
- nonwovens are used as geotextiles, early cultures and as covers on diapers, as filters, as upholstery fabrics or as cladding and covers in vehicle construction.
- Nonwovens are to be understood to mean a flat fiber structure which consists of long or continuous fibers which are laid on top of and next to one another in the random position and which are connected to one another by needling, melting or an adhesive and are thus strengthened against unwanted dissolution.
- Differentiated manufacturing processes and raw materials, different fiber thicknesses and lengths, types of consolidation and basis weights make it possible to produce almost any number of different types of nonwovens. They can be porous or dense, absorbent or water-repellent, hard or soft. In contrast to conventional woven and knitted fabrics, nonwovens are characterized by their wide range of variations.
- the nonwoven preferably consists of a spunbond which is stretched in the circumferential direction of the cylindrical bale and is made of a polyolefin material, preferably polypropylene.
- the stretching in the circumferential direction of the cylindrical bale gives the nonwoven a correspondingly increased tensile strength, which is necessary in order to be able to withstand the expansion forces of a pressed cylindrical bale.
- the basis weight of the spunbonded fabric should preferably be between 7 and 26 g / m 2.
- the spunbonded nonwoven can also be lubricated (oiled), colored or stabilized against ultraviolet light.
- the fleece In order to increase the adhesion of the fleece to each other and to the underlying material of the cylindrical bale, the fleece can be inhomo-
- REPLACEMENT SHEET (RULE 28) have genes in the position of the fibers or filaments.
- the material of the cylindrical bale can pass through the holes or weakenings in the nonwoven thickness resulting from the inhomogeneities and thus cause the nonwoven to be additionally fixed on the cylindrical bale.
- the adhesion forces between the polyolefin nonwovens can be increased by blending the polyolefin raw materials with TPE's (thermoplastic elastomers) or cling-batches.
- Inhomogeneities of the fibers or filaments also favorably increase the adhesion of the nonwoven fabric surfaces to one another, so that they can better withstand the expansion force of the set cylindrical bale by entangling the fibers or filaments with one another.
- Targeted strengths in the longitudinal direction can also be achieved at different points by varying the thickness of the fleece over its width, while other points with a lower thickness have, for example, better vapor permeability. If the thicker zones are meandering over the length of the nonwoven, the nonwoven is more able to absorb torsional forces that act on the cylindrical bale. The effects described can be brought about or supported by any perforation.
- a spunbonded nonwoven according to the invention can be processed by means of binding devices on balers which are equipped with a net, mesh or film material for binding. This avoids retrofitting the balers. Since a nonwoven web with comparable strength is thinner than the corresponding Raschelnetz- or Netzgittermaterial, there is the additional advantage that a roll of material with the same diameter gives a much greater length of binding material and the user of the baler therefore has to insert a new roll less frequently.
- a spunbonded nonwoven In order to be able to produce a nonwoven made of polyolefinic material that can be used as a binder, a spunbonded nonwoven must first be formed from continuous filaments. The filaments are then connected to one another by calendering, heating and / or by means of adhesive and the spunbonded nonwoven web is then stretched, preferably in a ratio of about 1: 2, in order to increase the strength.
- the stretching unit is preferably integrated into the machine for producing the spunbonded fabric, in that the spunbonded nonwoven web runs into the stretching unit after passing through the calendering rollers and only then is rolled up to form spunbonded nonwoven rolls.
- REPLACEMENT BLAIT (RULE 26) is wrapped. Zones of different filament density and / or strengthening in the longitudinal and / or transverse direction can be incorporated into the spunbonded nonwoven web.
- polystyrene resin in addition to the polyolefins or polypropylene described as a material for the nonwoven, other synthetic fiber materials, such as aromatic plastics such as polyester, can also be used.
- FIG. 1 shows an enlarged cross section through a spunbonded fabric during manufacture
- Figure 2 shows a garbage press for processing nonwovens as a binder
- FIG. 3 shows a cylindrical bale of agricultural straw material tied with a fleece.
- the fibers 2 of a nonwoven 4 can be seen, which in the tangled position are fed to the heated calendering rollers 6 in the conveying direction F.
- the supplied nonwoven mat can be laid inhomogeneously in order to create zones of different material thickness.
- the fibers 2 consist of a polyolefin, preferably polypropylene.
- the calendering rollers 6 press the fibers 2 against one another, and the heating 2 fuses the fibers 2 to one another at their contact points 8.
- more or less strong compression and consolidation of the nonwoven in the longitudinal and / or transverse direction can be achieved.
- needles can also cause the fleece 4 to solidify by felting the fibers or by pouring in an adhesive.
- Behind the calendering rollers 4, one or more faster-running so-called godets can be arranged, which pull the ves apart in the conveying direction and thus cause the nonwoven to be stretched.
- Recesses remain in the surface of the finished nonwoven, which allow the nonwoven surfaces to be well interlocked with one another and with the material of the cylindrical bale.
- FIG. 2 shows a garbage press 10 to which the garbage to be packed into a cylindrical bale is fed via a store 12.
- a container is installed on the garbage press 10, in which a roll of fleece 14 is inserted.
- the nonwoven web 16 is conveyed into the press chamber via drive and deflection rollers 18.
- the nonwoven web 16 is conveyed between the garbage bale and the press rollers delimiting the press chamber until the nonwoven web has made at least about 1.5 revolutions with the garbage bale. From this minimum number of revolutions there is sufficient adhesion of the fleece to bind the garbage bale with sufficient strength.
- this binding technique is already known from the devices for network binding.
- An agricultural round baler that works according to the fixed chamber principle has a similar structure to the garbage press and can process a nonwoven as a binder in a comparable way.
- Agricultural round balers with a variable chamber can also use the devices known for net binding for processing nonwoven webs.
- FIG. 3 shows a cylindrical bale 20 made from agricultural straw which is tied with a nonwoven web 16 according to the invention.
- the nonwoven web 16 is applied to the outer circumference of the cylindrical bale 20 so that one end of the nonwoven web 16 overlaps at least parts of the underlying nonwoven web. Crops can pass through holes 22 to the outside through the nonwoven web 16 and thus support the fixing of the overlapping nonwoven web parts to one another. Instead of or in addition to a perforation, the nonwoven web 16 can also have zones of lesser material thickness through which stalk material can then pass. The evaporation of moisture from the cylindrical bale can also be positively influenced by equipping the nonwoven web 16 in this way.
