| 摘要 |
The invention relates to a method for producing plastic profiles, in which a first profile is initially produced by extruding a profiled bar (6) through an extruder (2) and molding said profiled bar (6) in a first extrusion die nozzle (3a) that is connected to the extruder (2), whereupon the profiled bar (6) is calibrated in a first calibrating die (4a) located on a calibrating table (5) and chilled. The extrusion die nozzle (3; 3a, 3b) and the calibrating die (4; 4a, 4b) have to be replaced so as to be able to produce different profiles. In order to keep idle times as short as possible while changing dies, freely movable manipulating devices (9, 18) are used for replacing the extrusion die nozzle (3; 3a, 3b) and the calibrating die (4; 4a, 4b). |
