DESCRIPTION:
BRIEF SUMMARY
The invention relates to a device for manufacturing thermo-insulated compound profiles for windows, doors and facades, wherein metal profiles to be joined to form the compound profile are provided with at least one longitudinal groove in which are secured insulating connecting webs, while press rollers, located opposite one another in pairs at right angles to the profile axis press on the outer sides of the connecting webs against the retaining strips bounding the longitudinal grooves of the metal profiles, and press together these retaining strips and the base of the connecting webs engaged in the longitudinal grooves.
A known device of the above-mentioned type follows from German Auslegeschrift No. 2, 727, 060. The design described therein also uses press rollers located opposite one another in pairs for pressing the metal profiles, to be joined to form a compound profile, and connecting webs together, the press rollers being pressed against one another either by means of pneumatic cylinders or by spring force. If production tolerancies which cannot be avoided arise at the metal profiles, then although the press rollers can yield under the force of the cylinder or the compression springs, they do so under the disadvantage that this causes a non-uniform pressure distribution on the retaining strips of the two metal profiles. Consequently, the press joint, and in this respect the strength of the compound profile, between each of the metal profiles and the connecting webs is impaired.
As a consequence of the prior art referred to, it is the object of the invention, despite existing production tolerancies of the metal profiles to be joined, to always achieve an equally large pressure distribution of the press rollers on the retaining strips and consequently to uniformly secure the connecting webs in the profile grooves.
To achieve the said object, a device having the characteristics indicated in the Patent Claims is proposed.
The advantage achieved by the invention is that a press roller, formed from at least two forming discs, which can be displaced non-positively and inter-dependently in the roller plane and are supported on the roller hub, can always compensate for all dimensional deviations occuring at the metal profile in such a way that the same pressure force is exerted on all of the retaining strips of the metal profiles to be pressed together with the connecting webs. In this way, quality differences in the compound profiles manufactured by the device according to the invention are avoided; this was not possible with earlier machines. These aspects are of special importance for processing large profile sections, because the production tolerancies increase with profile width.
An embodiment example of the invention is described with reference to the drawings, wherein in detail;
FIG. 1 shows a side view of a production device according to the invention,
FIG. 2 shows a partial section drawn to an enlarged scale running along section line A-B in FIG. 1,
FIG. 3 shows a horizontal section, through section line C-D of the press roller in FIG. 2 sub-divided into two forming discs, and
FIG. 4 shows the vertical section E-F in FIG. 3 of this press roller formed by two forming discs.
FIG. 1 shows a production device, which is provided with press rollers 2, located opposite one another in pairs on the machine frame 1, and a horizontal guide roller pair 3 acting at right angles to the direction of pressure of the press rollers 2. Located at the end of a support arm 4 extending from the machine frame 1 is a support roller 5 located downstream from the horizontal guide roller pair 3, the vertical position of which support roller 5 can be varied by means of a spindle adjustor 6 for determining the position of the metal profiles 8 and 9 to be joined to form the compound profile 7. The finished compound profile 7 leaving the press rollers 2 is drawn off over a roller table 10.
FIG. 2 clearly shows in detail how the device shown in FIG. 1 is constructed. It can be seen from FIG. 2 that the metal profiles 8 and 9 formin
