Embodiment Construction

[0054] figure 1 Schematic diagram showing a cross-section through a textile covering (1) onto which a three-layer membrane (2) made of several membrane layers (22, 24, 26) is laid . Facing said fabric covering (1) and laying on said fabric covering first surface (11), the force-transmitting conveyor belt on the later outer surface is a first layer (22) of a first thermoplastic material , this first layer is formed after fixation of the multilayer film (2) with the figure 2 The first coating of the impregnated area is also shown in detail in . Said second layer (24) is a thermoplastic top layer which is also closed after fixing of said multilayer film and said layer (26) is an intermediate layer, here a copolyamide for said layer (22) An interposer is attached which allows peeling of the opposing layer (24).

[0055] figure 2 shown in figure 1 The examples shown in , after applying heat and if necessary pressure to the surface of the multilayer film. The first layer (2...

Abstract

The invention relates to a power transmission conveying belt, having a base structure made of polyurethane (30) and a textile overlay (1) and comprising a first coating made of a first thermoplastic material (22') on the surface (11) of the textile overlay (1), which first coating forms an impregnation, has a melting temperature from 80 DEG C to approximately 145 DEG C, and penetrates at least partially into the textile, and comprising a second coating (26) made of a second thermoplastic material on the first coating, which second coating has a higher melting point. The coatings can be applied successively to the textile overlay (1) before the casting of the polyurethane or can be overlaid as individual films or as multi-layer film and applied to the textile overlay by heat and pressure. The coating acts to reduce abrasion and prevents the through passage of the belt polyurethane.

Description

technical field [0001] The present invention relates to a force-transmitting conveyor belt having: an elastic lower structure made of cast polyurethane; a force transmission area constructed on the lower structure; a fabric covering in contact with the force transmission area. Background technique [0002] Textile coverings on conveyor belts, in particular toothed conveyor belts, primarily have the purpose of reducing wear and, in the case of toothed conveyor belts, suppressing the tendency to tear on the tooth edges and in the case of damage in the outer edges of the teeth Inhibits the tendency to further tear. [0003] Polyurethane belts are typically cast directly onto the fabric cover, allowing the polyurethane to react, crosslink and fix on the cover. In this case, the polyurethane penetrates at least partially into the fabric and passes through it. If the wear-resistant and possibly friction-reducing fabric cover is worn away during use, the polyurethane belt, which...
