Abstract

The two tubes (1, 2) to be joined are nutured to mate at the requisite angle, normally 90 deg., and a close fitting joining insert (3), with transverse grooves (4) on its inner forces, is placed inside the two tubes. The assembly is placed in a supporting framework (5) and a forming tool (11) with two knife edges, one lower and one upper and the corners of which correspond to the insert grooves, is brought against the tubing inside force. This pierces the tube wall and forms four lugs into the grooves, clamping insert solidly in tubes. The resulting frame may be used for windows or doors.
