  • Fabric-free belt
    Patent number: 6099972
    Abstract: A fabric-free belt has an oriented polyamide layer (1) as a tension layer. A rubber layer (2, 3) is arranged in the form of a laminate on both sides of the oriented polyamide layer (1). The rubber layers (2, 3) contain at least 1 part by weight, based on 100 parts by weight of rubber, of resorcinol, phenol, cresols or mixtures thereof and adhere directly to the oriented polyamide layer (1). An advantage of the invention is that no adhesion promoter coating has to be applied to the polyamide layer (1) or to the rubber layers (2, 3) for the production of the laminate.
