The equipment for welding plastic profiles to produce frames, especially window or blind frames, comprises at least two, preferably four, welding units (2,2',2",2'''), each of which has a fixed slide (4,4',4",4'''), a slide (5,5',5",5''') moving relative to the fixed slide and a moveable profile stop (18,18',18",18''') for aligning a profile. Profile alignment accuracy is improved by a centring device (10,10',10",10''') for individual adjustment of each profile stop relative to the appropriate welding unit. |
