Description of the invention (I) The present invention relates to a belt structure for a belt ', and in particular it serves as a compression belt in a corrugating machine. In a one-watt roll forming machine, a core paper sheet is heated with steam to increase its flexibility, and between a pair of toothed rollers that make the core paper corrugate. Paddle paste adhesive is applied to the pleats formed in the core paper '-a pad of paper is applied to at least one side of the core paper' is held together along the corrugated paper pleated tips. The backing sheet is pleated by a highly stretched compression belt that forces contact with the adhesive-coated core paper. This compression belt is placed under severe operating conditions. Because heat is used to evaporate water vapor, the belt must be able to withstand high temperatures. In addition, the belt must be continuously operated under strong pressure against the teeth of the rollers to obtain the required bonding pressure between the corrugated core paper and the flat backing paper. The belt must also be flexible and still have sufficient longitudinal strength and lateral stiffness to prevent wrinkling and allow precise tracking of the belt, otherwise the belt may drift undesirably from one side to the other. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs -------------------- Order- (Please read the precautions on the back before filling this page) European Patent EP-A No.-0630739 (Mitsubishi) discloses a belt intended to act as a compression belt to laminate a gasket to a corrugated core paper sheet. This disclosure describes an endless belt including a canvas core layer, an elastomer layer between the canvas core layer and a second surface, a canvas layer that can extend in the longitudinal direction of the belt. The structure also includes a non-stick material layer or coating Layer, such as a mixture containing a fluoropolymer. A layer of non-adhesive material is laminated on the surface canvas layer into two or more panels ' instead of including a ring structure. Flexible fractures at the panel joints are the most common failure factor. Practically, it has been found that the belts made according to the above disclosure are more than 3 paper sizes manufactured according to the Chinese National Standard (CNS) A4 (210 X 297 mm). Printed by the Consumers ’Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs 40S00 ^ A7 B7 5 Explanation of the invention (>) is expensive because the cloth from the canvas bottom of expensive and high-strength yarn must be woven, and because they are laminated by continuous first canvas layer, elastomer layer and second canvas Belts are easy to delaminate. This is always a concern when they are used in machines under high pressure, temperature and shear conditions. Ensuring accurate tracking of the laminated belt is also a problem, because it is difficult to ensure that the machine direction yarns in the two canvas layers are parallel to each other during the assembly of the multi-layer leather belt, especially when there is a sheet-like material layer in between. A difference of only one or two degrees can make the tracking or guidance of the belt on the machine quite different. It is an object of the present invention to provide a belt construction which can overcome or improve some of the above-mentioned problems associated with laminated corrugating machine compression belts. Accordingly, the present invention provides a compression belt structure for a corrugating machine, wherein the belt includes a single endless woven fabric, the type of which is at least partially impregnated with an elastomer. Aromatic Polyamide Yarn. Other suitable yarn materials, either alone or mixed with yarns of one or more different materials, include cotton, polyamides such as nylon 6 or nylon 6.6, polyester, glass, PBO, PVA, PEEK, or polyketones. The fabric is preferably fully impregnated with an elastomer. The elastomer at least partially impregnated into the base fabric may be a natural or synthetic rubber or resin, for example, silicone rubber, styrene butadiene rubber; ethylene propylene rubber; butyl rubber; fluoro rubber; hydrogenated nitrile rubber or PTFE. Elastomers can be reinforced with short fibers or particles such as silicon powder or ceramic nanoparticles. These will improve the abrasion resistance and strength of the anti-elastomeric layer. 4 This paper size is applicable to the Chinese National Standard (CNS) A4 specification ⑵Q x 297 meals.

Description of the invention (^), and silicone rubber is preferred because it has good release Sex. Elastomers typically have a Shore A hardness of at least 60. The surface of the paper contact pad of the belt may be provided with a coating or layer of a low-viscosity material that resists the combination of external materials, preferably a fluoropolymer such as PTFE, which may be mixed with an elastomer. However, antifouling can be provided by including a fluoropolymer in an elastomer mixture used to impregnate the base fabric. The surface coating may be applied by lick-coating to create a continuous layer, for example, by the technique described in British Patent GB-A-2250696. Other ingredients, such as antistatic agents, can be added to the elastomer. The antistatic agent may include stainless steel powder, polyaniline, conductive pigment, carbon fiber, or conductive polyurethane. A preferred embodiment of a belt construction according to the present invention will now be described by way of example and with reference to the accompanying drawings, in which: FIG. 1 shows a belt for a corrugating forming machine according to the present invention: and FIG. 2 is a comparison according to the present invention. An enlarged sectional view of the belt of the preferred embodiment. Referring first to FIG. 1, a tile forming machine includes a first ridge roller 10 and a ridge roller 11 meshing with the first ridge roller 10. A first core paper sheet 12 is fed into the jaws between the toothed rollers ′ and is formed in parallel ridges and grooves by the pressure acting between the rollers 10 and 11. The corrugated sheet is carried by a roller U to engage a second flat pad sheet 13 after the adhesive is applied to the exposed ridges 12 of the paper 12 by the device 14. 5 I paper size applies to China National Standard (CNS) A4 specifications (210 X 297 Gong Chu 1--I t ϋ I n I > ϋ ϋ (please read the precautions on the back before filling this page) Order: Economy Printed by a member of the Ministry of Intellectual Property, Consumer Cooperative, 4080〇β Α7 Β7 5. Description of the invention (ψ) The pad paper 13 is forced into an extension jaw by a compression belt 15 under elevated temperature conditions and reaches the adhesive-coated Ridged peaks. The belt 15 is guided through the jaws by the rollers 16, 17. The laminate thus produced is pulled away from the roller 11 for winding or further processing. A belt according to the invention is advantageously in the extended jaw on the roller 11 One acts as a compression belt 15 on a substantially circular arc. A preferred embodiment of a belt fabric is shown in an enlarged exploded section in Figure 2. The fabric includes a core or bottom woven fabric 20 which is fully impregnated with an elastomeric material 21 and encapsulated In other words, the elastomeric material 21 is thick enough to prevent the board from generating marks due to the core fabric layer 20. The elastomeric material 21 is provided with a coating or thin layer 22 of an antifouling material. The elastomeric material can be impregnated with a coating Or layers applied separately or simultaneously To the woven core fabric 20 to form a single-shell encapsulation material. The latter is a simple woven fabric such as Kevler or similar aromatic polyamide yarns, and the weft and warp yarns extend approximately in the direction of the mechanism and cross mechanism The elastomer 21 is a styrene butadiene rubber and the coating 22 is PTFE. The yarn of the fabric core 20 may alternatively be or may contain one or more of cotton, polyamide resin, polyester, glass, PBO , PVA, PEEK or a mixture of polyketones. Yarns can be multifilament, monofilament and / or twisted. Elastomers can be silicone rubber or include styrene butadiene rubber; ethylene_propylene rubber; butyl rubber; gas Rubber; hydrogenated nitrile rubber or PTFE, or a mixture of two or more of them. Elastomer 21 contains an antistatic agent whose type is stainless steel powder added to the elastomer. Other antistatic agents that can be used include polyaniline, Electrical conductivity 6 This paper size is applicable to China National Standard (CNS) A4 (210 X 297 mm) ------------- Shock --- (Please read the precautions on the back before filling in this Page) Order mm A7 _ B7 Employee Consumer Cooperatives, Bureau of Intellectual Property, Ministry of Economic Affairs (F) Pigment, carbon fiber, or conductive polyurethane. Coating 22 is optional 'but may be any suitable fluoropolymer or other low viscosity material', for example, ormocer and xanthone However, low viscosity can be obtained by including a fluoropolymer in an elastomer, which can be concentrated toward the paper contact surface of the belt. The low viscosity coating can include an elastomer so that the coating's elasticity matches the impregnation 21 to avoid cracking or other breakage of the coating. The core fabric 20 may be a canvas material or any desired weaving type, preferably with sufficient clearance to allow the elastomer to penetrate the fabric 20 and substantially Fully impregnated fabric. In a preferred embodiment, the fabric 20 is woven in a flat 2/3 twill, semi-triple, or 2-layer (8-pedal) woven fabric and loop-shaped, the latter being preferred because higher thickness and permeability provide good Elastomer penetration. Typically, the core fabric will contain 20-40 MD yarns per inch and 8-25 CD yarns per inch, providing a base fabric with a thickness of 1 to 2.5 mm. The belt according to Fig. 2 does not delaminate because it does not include any pieces that are bonded or laminated together face to face. Having a single fabric core also reduces the number of expensive high-strength yarns required and the need to weave two or more base fabrics. In addition, the difficulty of tracking is eliminated, which may be caused by even a small deviation of one or two degrees between the yarn directions of the overlapping fabrics, so that the belt tracking is improved. The belt is, for example, 1100 to 3100 mm wide, 1.2 to 3.5 mm thick, has an elongation of 4 to 11% at break, and has 2-5 and 4% at 23 and 150 ° C (load = 50 kg Force / cm belt width). It also has a friction coefficient of less than 0.3 with respect to iron on at least one surface, and can be continuously operated in a steam atmosphere at temperatures up to 250 ° C. 7 (Please read the notes on the back before filling this page)-*-\ 9
