Method and device for the production of tubular structures that are reinforced with a strengthening support
摘要:
Disclosed is a method for producing tubular structures (1) which are made of rubber and strengthening support layers (2, 3), comprising the following steps: a) a first rubber layer (2a) is applied to a series of successive rigid cylindrical mandrels (5) that are coupled to each other and are driven at a speed of advancement (v) in the direction of an axis of advancement (X) by means of a first extruding unit; b) a first filament layer is applied at defined setpoint filament angles (α1) relative to the axis of advancement (X) by means of a bobbin creel unit (10a) which is provided with means rotating around the advancing mandrels (5); c) at least one additional rubber layer (2b) is applied on top of the first filament layer by means of another extruding unit (4b); d) the speed of advancement (v) of the mandrels (5) is continuously measured; e) the rubber quantity applied by the first extruding unit (4a) is regulated according to the measured speed of advancement (v) so as to obtain a defined setpoint thickness for the first rubber layer (2a); f) the rotational speed of the first bobbin creel unit (10a) is regulated according to the speed of advancement (v) during rotation around the mandrels (5) so as to obtain a filament layer having the defined setpoint filament angles (α1).
