Apparatus for making profiled bars comprising profiled metal cores and profiled facings

摘要

Apparatus is provided for making profiled bars for windows, doors and other frames. The profiled bars are profiled metal cores and profiled facings having angled side flanges. The apparatus includes a carrying frame, a conveyor line for handling the profiled metal cores, an adhesive-applying station in the carrying frame, tangentially extending feeders with conveying members for handling profiled facings to be applied to opposite sides of the profiled metal cores, which feeders are provided on the carrying frame behind the station in the direction of travel of the conveyor line and include spreading wedge assemblies for spreading angled side flanges beyond edges of side walls of the profiled metal core. To permit an adaptation of the profiled facings to any distortion of the profiled metal cores, the adhesive-applying station comprises subassemblies which are disposed on opposite sides of the conveyor line and include applying rollers which have vertical axes and are pivotally mounted for automatic adaptation to any distortion of the profiled metal core which is to be coated, the feeders include belt guides, which are mounted close to the side faces of a profiled metal core, and converging members for applying contact pressure to the angled side flanges are provided in the belt guides.
