A method is disclosed for the manufacture of heat- insulating, assembled profile sections for windows, doors and facades, in which two metal profile sections 8, 11, which are to be joined to form an assembled profile section 13, have longitudinal grooves, in which connecting strips 7 are inserted, which together with the metal profile sections 8, 11 form an insulating chamber 9, and which are fixed to the basic part thereof engaged in the longitudinal grooves by deformation of the holder ribs 10, 12, which define the longitudinal grooves. In order to achieve an absolute dimensional accuracy and uniform strength characteristics of the assembled profile sections despite the manufacturing tolerances in the metal profile sections 8, 11, and the connecting strips 7, and with a view to being entirely independent of all cross-sections, dimensions and shapes of profile sections it is convenient to proceed as follows: a) the connecting strips 7 are drawn unilaterally into the corresponding longitudinal groove in one of the metal profile sections 8, 11 to be joined, b) the holder ribs 10 fitted in an insulating chamber 9 or the basic part of the holder ribs 10 bordering the connecting strips 10, which are engaged in a longitudinal groove, are deformed, c) the second metal profile section 11 is pushed like a cover on to the first metal profile section 8, and d) the holding ribs 12 running outside on the insulating chamber 9 are deformed against the basic part of the connecting elements 7, which are not yet fixed in the longitudinal grooves (fig. 1). <IMAGE> |
