Embodiment 1

[0046] The weaving of some fabric strips by warping on a Raschel machine has the following characteristics:

[0047] Production: Liba (LIBA)

[0048] Model: RACOP-06

[0049] Number of knitting needles: 1

[0050] Width of knitting needles: 130″

[0051] Number of bars: 6 (3 of which form a mesh)

[0052] Specifications: 14 pins per inch

[0053] Speed: close to 600 lines of mesh per minute

[0054] This fabric type is standard and its workings and possibilities are known to anyone skilled in the art.

[0055] At the same time 25 types of fabric strips (indicated with reference numeral 2) having a width between 50-200 mm were obtained, which were characterized as follows.

[0056] - The specific process of the three-bar structure is as follows:

[0057] P-1:2-0 / 0-2 / / Connect with post-ring chain

[0058] P-2: 2-4 / 2-0 / / connect with knitted fabric

[0059] P-3: 0-0 / 8-8 / / Connect with the weft on the four pins

[0060] -Threading and material of bar:

[0061] P-1: full ...

Embodiment 2

[0076] In the second preferred embodiment, compared with the first preferred embodiment, the following changes are introduced:

[0077] The specific process of the four-bar structure is as follows:

[0078] P-1: 2-0 / 0-2 / 4-6 / 6-4 / connected with offset post ring chain

[0079] P-2: 4-6 / 6-4 / 2-0 / 0-2 / / Connect with offset post ring chain

[0080] P-3: 2-4 / 2-0 / / connect with weft

[0081] P-4:0-0 / 8-8 / / Connect with the weft on the four pins

[0082] Bar threading and material:

[0083] P-1: 1 full-1 empty; 0.22mm diameter polyester monofilament (PET), or 0.20mm diameter polyamide monofilament (PA)

[0084] P-2: 1 full-1 empty; 0.22mm diameter polyester monofilament (PET), or 0.20mm diameter polyamide monofilament (PA)

[0085] P-3: full wear; 500 dtex polyester (PET) multifilament

[0086] P-4: full thread; 0.22mm diameter high shrinkage polyester (PET) monofilament

[0087] The strip obtained during weaving is then used to complete the forming phase, which is the same as describ...

Embodiment 3

[0093] In the third preferred embodiment, compared with the first preferred embodiment, the following changes are introduced:

[0094] The specific process of the two bar structure is as follows:

[0095] P-1: 2-0 / 0-2 / / link with offset post ring chain

[0096] P-2: 0-0 / 6-6 / / Connect with the weft on the three pins

[0097] Bar threading and material:

[0098] P-1: full thread; 68×2 tex (tex) glass fiber multifilament

[0099] P-2: full thread; 68×2 tex (tex) glass fiber multifilament

[0100] Unlike those belts obtained in the first and second examples, the belts obtained with such connection structures, materials and wefts are characterized by their resistance to high temperatures, the belts can support a temperature of 600°C 90 hours without losing more than 50% of its mechanical properties.

[0101] In the forming stage of this embodiment: with silicon copper or resin mixture, for example the acrylic acid PR resin impregnation belt that REPSOL company manufactures, th...

Abstract

The invention relates to a method of producing protective tubes. The inventive method comprises the following steps consisting in: producing a plurality of flat warp knit bands using a Rachel loom; and shaping said flat bands such that the longitudinal ends of each flat band join together and overlap each other, thereby forming a tubular shape. The inside diameter of the tube and the overlapped segment can be controlled and defined by the method and said inside diameter can be virtually limitless.

Description

[0001] The invention relates to a method of manufacturing a protective tube formed from a number of interconnected wires. Background of the invention [0002] Once the car is vibrated, it produces noise that disturbs passengers. Some of this noise is due to the vibrations causing the cables to hit the vehicle body. Consequently, the vibrations also lead to wear on the cable as well as on the protective tube. [0003] To prevent these hazards, protective tubes are sometimes used to cover vehicle cables and absorb noise. [0004] These protective tubes are made of braided wires of plastic material which has the advantage of being elastic and adaptable to different cable diameters. In order to provide protective tubes with the above-mentioned properties required for absorbing noise, these protective tubes also comprise threads of textured material. [0005] In Patent No. ES-A-2,210,854, belonging to the same proprietor as the present application, the insulating tubes described...
