Description

A description is given of a method for producing entire frames made up of plastic profiles for outer frames and sash/leaf frames. This method consists in the fact that the outer-frame profiles and the sash/leaf- frame profiles are connected temporarily to one another with the aid of at least one interposed spacer piece, which compensates for the difference in the frame outer dimensions in the direction of the frame plane, and, in this assembled arrangement, are jointly cut to size, welded and, if appropriate, finished. In this arrangement, the same (or another) spacer piece also gives an additional distance between the frame profiles in the direction perpendicular to the frame plane, which additional distance, depending on the thickness of the frame profiles, is set to a range of from 3-10 mm. The spacer piece may be designed as a small block and is, preferably analogously to the frame profiles, an elongate profile consisting of a thermoplastic material which does not undergo welding with the material of the frame profiles. Expediently, it has at least two parallel surfaces which come to bear on the outer frame and sash/leaf frame, between two mutually parallel surfaces of the outer frame and of the sash/leaf frame, and retain the frames at a predetermined distance from one another. The temporary assembled arrangement of the profiles and the spacer piece is produced by means of a shrink film or of a corresponding auxiliary means, which can be easily removed after the entire frame has been finished.
