<p>Disclosed is a flat belt ( 2 ) that is made of elastomer material ( 46 a , 46 b) and is composed of a first belt part ( 2 a) and a second belt part ( 2 b). The first belt part ( 2 a) is reinforced with a tensile support layer ( 4 ) comprising cords. The aim of the invention is to reliably prevent layers from separating while optimizing bonding of the belt material to the tensile supports ( 4 ). Said aim is achieved by providing the first partial belt ( 2 a) with grooves with the aid of winding noses ( 42 ) of a molding wheel while the second partial belt ( 2 b) forms a filling for the grooves ( 44 ) of the first partial belt ( 2 a). Preferably, the tensile support layer ( 4 ) is centrally placed on the neutral bending plane of the finished flat belt ( 2 ). The first ( 2 a) and the second partial belt ( 2 b) can be made of different elastomer material ( 46 a, 46 b). Furthermore, at least one of the two surfaces of the belt ( 2 ) can be coated and/or be provided with a longitudinal or transversal profile.</p> |
