The invention relates to a device for the continuous production of plastics/metal composite panels, in particular those having hollow chambered sections, from thermoplastic polymers (3) and continuous metal sheets (6, 7), consisting of at least one plastics melting control system (1), calibrators (4, 5), feeds for the metal sheets (10, 11) and a draw-off unit (9), with the feeds for the metal sheets (10, 11) being arranged respectively above and below the melting control system (1) and the calibrators (4, 5) being immediately adjacent to the feeds (10, 11) and the melting control system (1).

1. A process for the continuous production of plastics/metal composite panels, by melt extrusion of thermoplastic polymers between at least two metal sheets, comprising the steps of: supplying at least two metal sheets, at least two feeds for the metal sheets, one for each sheet, and at least two perforating rollers; perforating at least two metal sheets with the at least two perforating rollers; continuously guiding at least two, optionally preheated by pressing rollers or pressure clamps, metal sheets with perforations therein, each from a holder one above and the other below a plastics extrusion nozzle, to a heatable melting control system and positioning the metal sheets with perforations in spaced relationship from one another with calibrators, wherein the calibrators are arranged immediately adjacent the feeds ant the melting control system; extruding plastics material into the space between each of the two sheets in order to produce a webbed connection in the area of the perforations in the sheets; cooling down of the plastics melt, and fixing the sheets with regard to their distances apart as the continuous panel is drawn off. 2. A device for continuously producing a plastics/metal composite panel comprising: a supply of at least two metal sheets, at least two feeds for the metal sheets, one for each sheet; at least two perforating rollers, one for each sheet for introducing perforations therein; a heatable melting control system including an extrusion nozzle for introducing a plastics melt between the sheets and through the perforations; guiding means for guiding each sheet to the heatable melting control system; calibrators for positioning the metal sheets in spaced relationship from one another; a draw-off unit for removing the composite plastics/metal panel; wherein the feeds for the metal sheets are arranged with one feed above and the other below the melting control system; and wherein the calibrators are arranged immediately adjacent the feeds ant the melting control system and wherein the feeds are provided with pressing rollers, or pressure clamps which render possible a preheating of the sheets prior to contact with the plastic melt and are optionally heatable. 3.The device according to claim 2, characterized in that the extrusion nozzle is design in the form of a slot nozzle for the production of plastics webs between the metals sheets. 4. The device according to claim 3, characterised in that the slot nozzle is constructed in the form of a nozzle having a multiple V-, X-, I-, T- or double-T shape. 5. The device according to claim 2, characterized in that the extrusion nozzle possesses in addition air-atomising nozzles. 6. The device according to claim 2, characterised in that the feeds run parallel to the position of the sheets passing into the calibrators. 7. The device according to claim 2, characterised in that the calibrators act on the sheets by magnetic force or under a partial vacuum. 8. The device according to claim 2, characterised in that the feed of the plastics melt passes from an extruder laterally out of the melting control system.
