Abstract: Disclosed is a flat belt (2) that is made of elastomer material (46a, 46b) and is composed of a first partial belt (2a) and a second partial belt (2b). The first partial belt (2a) 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 (2a) with grooves with the aid of winding noses (42) of a molding wheel while the second partial belt (2b) forms a filling for the grooves (44) of the first partial belt (2a). Preferably, the tensile support layer (4) is centrally placed on the neutral bending plane of the finished flat belt (2). The first (2a) and the second partial belt (2b) can be made of different elastomer material (46a, 46b). 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.

Abstract: The two belt parts (2a, 2b) of a belt (2) made of plasticatable material are produced with the aid of a first station (6) and a second station (8). The first station (6) includes a rotatable mold drum (14) and a continuous mold belt (18). The mold belt (18) is brought together with the mold drum (14) along a peripheral section via an upper pressure roller (20), a lower pressure roller (22) and a tensioning roller (24) in such a manner that a hollow mold space (26) is formed between the mold drum (14) and the mold belt (18). An extruder (10) is mounted forward of the hollow mold space (26). Furthermore, the first station (6) includes a filament feed (28) for forming a reinforcement layer (4) in the first belt part (2a). For a simplified manufacture of the belt (2), the second station (8) includes only a direction-changing roller (30) in addition to the extruder (12) and a mold drum (16).

Abstract: A linear drive includes a toothed belt (2) driven by direction-changing rollers (1) in the pretensioned state. The toothed belt (2) has at least one tension reinforcement. The teeth (3) of the belt (2) engage in the teeth gaps (4) of a linear toothed counterpiece (5) over a specific length. The pitch of the teeth (3) of the belt is slightly less up to 0.8% than the pitch of the toothed counterpiece (5) in the pretensioned state of the toothed belt (2) and during loading of the toothed belt which occurs during operation under load. The tooth flank (6) of the tooth (3) of the belt is at right angles or almost at right angles to the plane of the tension reinforcement (7) and the tooth gap (4) of the toothed counterpiece (5) is approximately 20% to 80% wider than the width of the tooth (3) of the belt. The belt teeth (3) are elastically configured compared to the high stiffness of the tension reinforcement (7).

Abstract: A toothed belt is provided with at least one end attachment part for connecting an end portion of a toothed belt to a housing part or a component to be driven. The end attachment part is a formed strip made of metal or plastic in order to make the attachment of the toothed belt quicker and simpler. The strip has elements or sections which engage in the teeth of the end portion and are securely held therein. In the assembled condition, the end attachment part includes a portion to facilitate a mechanical connection at its end facing away from the end portion of the toothed belt.
