Production method for window and door frames wood-metal profiles, and relative profiles obtained with such a method.

摘要

A method for producing wood-metal profiles or section bars for window and door frames by continuous injecting a binding material (B) into a space between said profiles or section bars (A, C), said method comprising: - using a wood spline (A) with at least one longitudinal slanting groove-milling (3) made on the surface intended for receiving the joint binding material (B); - using a metal profile (C) provided with longitudinal undercut slanting or thickened end tongues on the space intended for receiving said binding material (B); - continuous injecting a binding material (B) into said space; and wherein the contact surface between the binder (B) and the metal profile (C) is not glued for allowing longitudinal sliding and avoiding distorsions; joint between profiles or section bars for forming window and door frames is also carried out by means of grooves for injecting binding material.
