Abstract
The flat drive belt has a layered build-up comprising at least one tensile layer (1) which has a modulus of elasticity of 20,000-250,000 N/mm.sup.2 and which is positively embedded between two thermoplastic hot-melt films (3) having a modulus of elasticity of 40-600 N/mm.sup.2. Friction layers or friction structures (4) of an elastomer material having a modulus of elasticity of 2-40 N/mm.sup.2 are built up on the hot-melt films (3). The individual layers of the flat drive belt can be produced with high precision and, as a composite, form a sheet-like structure which is very regular with respect to thickness and weight per unit area. The starting material, produced as meter ware, for the flat drive belt can be cut without effort by the user from rolls and can be joined under the action of pressure and heat into a continuous form, without thickenings and joint gaps, in the way required for the kinematic behavior of fast-running drive belts.
