Abstract: A conveyor belt is provided with advertising indicia on a visible surface thereof. A film of transparent plastic covers the visible surface of the conveyor belt to protect the advertising indicia. The conveyor belt can be used in combination with a cashier's counter as a method of advertising to customers in a store.

Abstract: A driving belt has a textile supporting element composed of multi-functional threads or yarns which contain plastic fibers of high breaking strength and heat-resistant natural fibers. The driving belt also contains an electrically conductive element. The supporting element is connected to a non-crosslinked plastic covering to form an asymmetric structure. The textile supporting element can be impregnated on the side facing away from the plastic covering. The electrically conductive element is either an electrically conductive filament in the multifunctional thread or yarn or an electrically conductive layer between the supporting element and the plastic covering. This asymmetric structure results in a favorable kinematic operating behavior and high efficiency, because the neutral bending plane of the belt comes to rest at a point very near the contact surface of an element to be driven.

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.

Abstract: A dimensionally stable synthetic internal support conveyor belt which comprises (a) at least one homogeneous, flat tape of a molecularly oriented plastic with a modulus of elasticity of 15,000 to 25,000 kp/cm.sup.2. This tape has a fixed profile on both of its large area surfaces and includes reinforcement ribs arranged with their components extending predominantly in the longitudinal direction of the tape. Binding layers are composed of an elastic material with a modulus of elasticity of 800 to 1,000 kp/cm.sup.2 and interlock with the profile on both sides of the tape. Each of the binding layers may be covered with a synthetic fabric. Each of the two binding layers with each of the two synthetic fabrics may be covered with a cover plate of elastomers or thermoplastics.
