Definitions

  • the invention relates to an idler fabric made from gimmi-repellent material as an intermediate layer in the formation of a roll with a rubber and / or rubber sheet.
  • Non-vulcanized rubber and / or rubber sheets tend to react with each other over time.
  • such surfaces must be separated from one another by sheet-like spacers when stacked on top of one another or when rolled up on a roll. This prevents the G / K fabric from sticking together.
  • sheet-like structures made of foils or fabrics which either have a rubber-repellent finish or are themselves rubber-repellent due to their material properties.
  • an idler fabric made of rubber-repellent work is advantageously used in the prior art Substances used, which is usually wound up with the G / K fabric on a roll, which is then unwound again in use, the idler fabric is separated from the structure and wound up for the next use.
  • Such coils consisting of the idler fabric and the G / K flat structure, can only be produced precisely at relatively low winding speeds, since if the winding speeds are too high there is a risk that air will be trapped when the winding or the package is built up. This leads to bubbles / corrugations in the G / K fabric, which is highly undesirable.
  • gases of this type can also be produced by the reaction of rubber and / or rubber which has not fully reacted, which likewise lead to warping in the winding.
  • irregularly corrugated fabrics are pulled off the roll, which lead to a high material output.
  • idler fabrics with a canvas structure are usually used, which have a relatively low transverse stability.
  • wrinkles can form in the fabric, which in turn leads to an impression in the G / K fabric. This is particularly the case when pulling apart and when winding the texiles Component to fear, which is a hindrance to the re-use of the idler tissue.
  • a fabric web which is to be used as a tire cord fabric web.
  • this fabric web has a tightly woven, stable tee, which has at least one woven-in weft thread, with which a width stabilization of the tee is ensured.
  • Such fabric webs reinforced only in the end area are not suitable for use as idler fabrics.
  • the invention is therefore based on the object of developing the idler fabric of the type mentioned at the outset in such a way that the formation of bubbles or imprints does not occur in the wrap consisting of G / K flat structures and idler fabric.
  • the problem is solved by a plurality of ribs provided at certain intervals in the weft and / or warp direction of the idler fabric.
  • the idler fabric according to the invention initially has the advantage that the surface structure of the fabric has, at certain intervals, transverse ribs which raise the adjacent G / K flat structure by a small amount compared to the area surrounding the ribs. This lifting creates a space in the area of the transition from the raised rib into the smooth surface, on which the structure no longer abuts. As a result, this space forms a channel that runs across the entire tissue at the front and rear ends of each rib. Inclusions of air can be prevented by this channel, so that a regular winding can initially be produced even at high winding speeds.
  • the G / K flat structures lying on top of each other are lifted off from the regions to be regarded as flat, so that largely tight adhesion of the flat structure to the fabric is prevented.
  • the arrangement of the ribs on the idler fabric is advantageously such that the adhesion of the G / K fabric is essentially limited to the ribs themselves, so that this results in an even easier separation from the fabric during processing of the G / K fabric.
  • the ribs also stiffen the idler fabric, even if it is made in a modified plain weave. This has the advantage that the transverse stability is thereby considerably improved, so that the tendency of the fabric according to the invention to form folds is substantially less than is the case with the prior art.
  • the idler fabric according to the invention advantageously has ribs running in the weft direction, these ribs being formed at regular intervals.
  • Such a rib is formed by combining several weft threads of the same diameter per warp lifting or lowering. Such ribs are then usually followed by areas in which only one weft thread is inserted per warp lifting or lowering, which has the same diameter as the weft threads that form the rib.
  • the rib can also be formed from at least one thick weft thread, while the surrounding areas are formed from thinner weft threads.
  • rib formation in the weft direction natural Lich also according to the invention, if this appears advantageous, a rib formation in the warp direction can be provided, with several warp threads are combined. A combination of the ribs in the weft and warp direction is also possible. However, as explained above, rib formation in the weft direction is preferred.
  • the spacing of the ribs is chosen according to the invention in such a way that the rubber layers lying on the idler fabric do not undergo any embossing or wave formation during winding.
  • a relatively narrow rib area adjoins a relatively wide area, in which only one weft thread is provided per warp raising or lowering. If one examines such a tissue in cross-section, ribs with a relatively small width a alternate with flat areas of a relatively large width b in a regular sequence (see FIG. 3).
  • the ribs are substantially wider than the areas of relatively small cross-section.
  • channel-shaped recesses run in the latter areas of relatively small cross-section or thickness in the tissue.
  • channel-like areas with a small cross-section and a small width are regularly connected to relatively wide areas with a large cross-section.
  • the rib area and the normal area have different heights (thicknesses).
  • the thickness d 1 of the normal area and the thickness d 2 of the rib area are in a ratio of 1: 1.3 to 1: 3, preferably 1: 1.5 to 1: 2.
  • the rib structure of the idler fabric is designed in such a way that no impressions can form in the G / K fabric roll.
  • both the distance between the ribs and the rib height, which results from the thickness, are decisive.
  • the distance between the ribs is advantageously longer, the smaller the thickness of a rib.
  • the ribs of the spacer fabric advantageously extend across the entire width, i.e. in the weft direction. Furthermore, as mentioned above, the ribs are distributed substantially uniformly over the entire width (warp direction), so that the rib regions alternate with normal regions or channel-shaped depressions in a regular sequence.
  • the materials for producing the spacer fabric according to the invention have a rubber-repellent property.
  • This equipment is based either directly on the materials used or on a subsequent finishing of the materials.
  • materials which have this rubber-repellent property are rubber-repellent polymers, in particular polyethylene and polypropylene.
  • materials can also be used which have only a relatively low rubber-repellent property, provided that these materials are or are made to be rubber-repellent.
  • cotton, rayon or polyester can be impregnated, for example with silicone materials or acrylates.
  • the threads used according to the invention can have the same thickness in the weft and / or warp direction. In this respect, only a single material is used to manufacture the idler fabric according to the invention.
  • - threads of different thicknesses can also be used in the weft and / or warp direction.
  • thicker threads can be used to produce the ribs than to produce the normal range.
  • two bobbins are required to insert the weft threads if the rib region is made with a thick thread and the normal region with a thin thread.
  • the type of weave of the idler fabric is chosen according to the purpose.
  • Modified basic weave types are usually used, for example plain weave, twill weave, cross twill weave, satin weave or Oxford weave.
  • the modified plain weave is preferred because, on the one hand, it is sufficiently cross-stable due to the rib weave and, on the other hand, it can also be produced cheaply on the usual dobby weaving machines.
  • modified basic binding type is the use of a common basic binding with the entry of several shots and / or to understand warp threads in the rib area, the adjacent areas being provided with the usual basic weave.
  • weaves can also be made with threads of different thicknesses in the warp and weft directions, wherein threads in the warp and weft directions are advantageously used in a range from 500 to 2000 dtex.
  • a first example of an idler fabric according to the invention is produced as follows:
  • a thread with 530 dtex is used in the chain, while a thread with 650 dtex is used in the weft direction.
  • the fabric itself is made in a modified plain weave. 4 - 7 shots per warp increase or decrease are entered for each rib. In the normal range, one weft thread is inserted for each warp elevation or reduction, it being possible for 2 to 8 adjacent wefts in the normal range to follow the rib region.
  • ribbon-like material with 650 dtex in the warp direction and 550 dtex in the weft direction is used.
  • the fabric is again made in a modified plain weave, with 3 - 5 wefts in the rib area, each with 1 warp raising or lowering, and in the normal range, one weft thread per warp lifting or lowering is provided, with this normal area only 1 - 2 weft threads next to each other the rib areas.
  • FIG. 1a shows a first idler fabric 10 which only shows four warp threads, the weft threads being shown indirectly by the black / white representation.
  • this idler fabric 10 has four warp threads 12-20, which each pass through two areas in the detail shown in FIG there is, further wefts connect laterally to this weft.
  • this normal region 24 has eight weft threads lying next to one another.
  • the checkerboard-like representation also shows that this follower fabric 10 is made in a modified plain weave.
  • the ribs 22 are each formed from four weft threads, each of which is inserted into a warp raising / lowering.
  • the warp thread 12 has four weft threads lying above it at the lower end, with one weft thread alternatingly at the top or at the bottom.
  • the second rib 22, which lies further up in FIG. 1a, has the warp thread 12 lying on the top, so that the four weft threads lie below.
  • FIG. 1b shows a further embodiment of an idler fabric 26, again only four warp threads being shown.
  • the same reference numerals are used as in Fig. 1a.
  • the ribs 22 are in turn formed from four weft threads, which are alternately above or below the warp thread according to the plain weave used.
  • the normal region 24 is designed such that only two weft threads lying next to one another are provided between the regions having the ribs 22. As a result, this embodiment is considerably shorter in its normal range than the embodiment according to FIG. 1a.
  • FIG. 1c A third embodiment of an idler fabric 28 in a modified plain weave is shown in FIG. 1c, the same reference numerals being used for the same parts.
  • the rib has seven wefts, during the normal range accordingly the embodiment according to FIG. 1b also only has two weft threads lying next to one another.
  • an idler fabric 30 is shown in the known cross-twill weave. It repeats in the transverse direction, i.e. towards the weft, every four warp threads 32-38 the binding.
  • FIG. 3 shows a cross section through the idler fabric according to FIG. 1a in an enlarged view. From this, both the width ratios between the rib areas 22 and the flat areas 24 from the widths a and b as well as the thickness ratios from the thicknesses of the flat areas 24 (d 1) and the rib areas 22 (d 2) can be seen.
  • the warp thread 12 extends through the areas 22 and 24, which each have the weft threads 42 and 44, respectively.
  • FIG. 4 shows a cross section through the idler fabric according to FIG. 1a in an enlarged representation, a G / K flat structure 46 being provided above this fabric. From this it can be seen that these fabrics 46 each touch the tip 48 of the rib 22 and then falls into the area 24, 24 channels 50 being formed at the transition between the rib 22 and the normal area, through which the gases generated or the trapped air can escape.
  • the idler fabrics according to the invention can advantageously be used directly in the tire, rubber, rubber or plastics industry.
