Plastic window and door profiled sections joining method and appliance

摘要

The adhesive is inserted into one or more grooves on the corner connections (3). V-shaped notches are cut on the end surfaces of the profiled bars used and extend over the entire surface. The notches have permanently elastic adhesive. Profiled reinforcements in the frame parts are widened by calibration. Corner connections have beads in the two side surfaces, and a groove on the underside into which the adhesive is poured. The reinforcements are in two parts with external and internal toothing, or as four-sided tubing.
