| 摘要 |
The invention relates to a device for producing and/or applying a substantially planar material combination (3) which is formed from at least two surface regions (1, 2) and has a predefined combined width (4), combined height (5), and/or combined length (6). Said device comprises a conveying unit (9) that defines a direction of travel (y) and has a conveying surface (11). The device also comprises an application unit (7) including an application nozzle (8) which has a slit-shaped outlet (24) extending substantially transverse to the direction of application (y) and which allows the first surface region (1) made of a first extrudate (21) and the second surface region (2) made of a second extrudate (21') to be extruded onto the conveying surface (11). The application nozzle (8) comprises at least one conveying unit (22; 22') for conveying an extrudate (21, 21') onto the conveying surface (11). The conveying unit (22) allows the conveyed volume, the conveyed mass, the conveying speed, and/or the conveying time of at least one of the extrudates (21, 21') to be controlled. |
