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). The spacing (32) between the direction-changing roller (30) and the second mold drum (16) equals the thickness of the belt (2) to be manufactured. To limit and guide the first belt part (2a) to be manufactured and/or the belt (2), the first mold drum (14), the second mold drum (16) and/or the direction-changing roller (30) are preferably provided with flange discs (14a, 14b; 16a, 16b and/or 30a, 30b). In order to make possible a targeted softening of the surfaces of the belt parts to be joined, the various rollers (20, 22, 34, 34′, 35, 35′) and the two mold drums (14, 16) can be provided with heating/cooling.
