Definitions

  • the present invention relates to a protection sheath, of the type formed from a fabric band, which adopts a curved configuration in section, so that the longitudinal edges overlap in greater or to a lesser extent, the sheath defining a tubular configuration with a longitudinal opening for the introduction inside the tubes or cables to be protected.
  • covers are made of fabrics made of fibers, or threads, monofilament or multifilament, of various materials, depending on the type of protection to be obtained: thermal, acoustic, anti-perforation, etc.
  • the fibers used can be aramid, polyester, polyamide, metallic, glass fiber, metallic threads, cellulosic fibers, or fibers of other materials suitable for the type of protection to be obtained.
  • the protective covers or tubes obtained have a more or less reduced thickness due to the structure of the fabric used for its conformation, which limits the degree of protection granted by the sheath or tube. Therefore the technical problem that arises is the obtaining of a cover that presents the characteristics of the mentioned covers, in which it refers to the possibility of being shaped so that it adopts a longitudinally open tubular configuration with overlapping ends, and that simultaneously present a significantly greater thickness, capable of increasing thermal, acoustic, anti-perforation, etc. provided by the case.
  • the protective sheath has been devised, object of the invention, which is constituted by a knitted fabric by warp, of three-dimensional configuration, elaborated in a double-biased machine, with various pin bars and its structural variants ; said warp fabric comprising: a structure or outer layer of greater consistency, an internal structure or layer, and an intermediate structure or layer of lower density and of a thickness between 5 and 65 millimeters.
  • the structure or outer layer of the warp knitted fabric is the one responsible, once formed the sheath as a longitudinally open tube, to provide the sheath with the flexibility and consistency necessary so that it can deform during the introduction of the tubes or cables or protect through the longitudinal opening.
  • the intermediate layer or structure, with lower density, or less compact is the one that acts as a separator between the inner and outer structures or layers, forming an intermediate chamber or space intended to increase the thermal and acoustic insulation provided by the cover and allow the passage inside and in the longitudinal direction of tubes or cables of smaller section than the thickness of said structure or intermediate layer.
  • the structure or inner layer is the one that collaborates with the structure or outer layer in supporting the structure or intermediate layer.
  • the warp knitting fabric, forming the sheath can include in its composition monofilament threads and multifilament threads of various materials, as long as it maintains the aforementioned structure.
  • the structure or outer layer has a substantially constant section, while the intermediate and inner structures or layers have a variable section or height, forming in the transverse direction of the structure or outer layer a series of bumps or battlements of decreasing section towards the inner side of the sheath.
  • the decreasing section of said protuberances or battlements determines that once formed the sheath, as a longitudinally open tube, said protuberances or battlements are arranged laterally attached, forming a substantially continuous coating on the curved inner surface of the structure or outer layer of The cover.
  • the outer, intermediate and inner structures or layers present in section some thicknesses substantially constant throughout their length.
  • the ligatures used in the warp knitting fabric are any of those indicated below: chains, tricots, wefts, inserts and / or their combinations and structural variants; the fabric comprising a combination of monofilament threads from 0.15 mm to 0.30 mm and / or multifilament threads from 150 dtex to 4000 dtex.
  • Figure 1 shows a cross section of an embodiment of the protective sheath.
  • FIG. 2 shows a cross section of the protective sheath, of the previous figure, in use position.
  • FIG. 3 shows a section in flat development of an example of realization of the knitted fabric by warp intended to form the protective sheath shown in Figure 1, and in which the intermediate and interior structures of the fabric form, on the face inside the structure or outer layer, a series of protuberances or longitudinal battlements.
  • FIG. 4 shows a flat developing section of the warp knitted fabric intended to form the protective sheath, the intermediate and inner structures of the fabric having a thickness substantially constant throughout its length.
  • FIG. 5 shows a perspective view of the protective sheath of Figure 1, provided in this case with means for closing the longitudinal mouth of the sheath.
  • the cover of protection (1) is constituted by a knitted fabric (2) by warp, of three-dimensional configuration, which has a structure or outer layer (21) of greater consistency, an internal structure or layer (22) and an intermediate structure or layer ( 23) of lower density, which in this embodiment has a thickness of 30 millimeters.
  • the fabric (2) is obtained with a double knit warp knitting machine with various pin bars.
  • the structure or outer layer (21) adopts a curved configuration, as shown in Figure 1, leaving the longitudinal edges (11 ) of the cover (1) superimposed to a greater or lesser extent and forcing the inner and intermediate structures (22, 23) to adopt the same curved shape.
  • the sheath (1) already formed has sufficient flexibility to allow the opening of the longitudinal mouth (12) of the sheath (1) and the introduction into the interior of the sheath of the cables or tubes (3) to be protected.
  • the intermediate layer or structure (23) of the warp knitted fabric has a lower thread density than the outer (21) and inner (22) structures, said threads of the intermediate structure (23) being oriented in a direction substantially perpendicular to the structures (21, 22), exterior and interior.
  • Said intermediate structure (23) forms an intermediate chamber or space intended to increase the thermal and acoustic insulation provided by the sheath (1) and to allow the introduction, in substantially longitudinal direction, of tubes or cables (3a) of smaller section than the thickness of said structure or intermediate layer.
  • the inner and intermediate structures (22, 23) of the knitted fabric (2) by warp define on the inner surface of the outer structure (21) longitudinal protuberances, referenced as (24), of trapecial section and decreasing width towards the inside of the sheath (1), so that once the sheath is formed with the tubular shape shown in Figure 1, said longitudinal protrusions are attached laterally, without constituting any impediment to the adoption of the open tubular form by the sheath (1).
  • the configuration of these protuberances is especially indicated in those cases in which the intermediate structure (23) of the tissue has a high thickness.
  • the intermediate structure (23) of the knitted fabric (2) per warp is of a smaller thickness, in this case having a substantially constant thickness throughout the entire length of the outer structure (21) .
  • the cover (1) has on the superimposed longitudinal edges complementary coupling means (13) for closing the longitudinal mouth (12) of the cover (1).
  • complementary coupling means (13) are represented in the aforementioned figure 5 by a double-sided adhesive tape.
  • the three-dimensional flat fabric is simultaneously formed in a double-size knitting machine, whose font 1 weaves the structure or outer layer (21) of the three-dimensional flat fabric, constituted by chain links , tricots on three, four or five needles and wefts on three, four or five needles, and whose font 2 weaves chains knitted in ribbed sections of 1, 2, 3, 4 or 5 needles joined by elastic or retractable threads that make up
  • the structure or inner layer (22) is formed by chains of chains and wefts on three needles, in corrugated sections of a needle and two needles respectively.
  • the structure or inner layer (22) is formed by chains and chains linked on two needles in corrugated sections of a needle and two needles respectively.
  • the structure or inner layer (22) is formed by chains and chains linked on a needle, in corrugated sections of a needle and two needles respectively.
  • the structure or inner layer (22) can additionally comprise a ligature with retractable thread.
