Patent ID: 8727760

Claim:
An apparatus for producing thermoplastic corrugated pipes, the apparatus being designed for producing corrugated pipes of nominal widths in a range from 600 to 2400 mm, the apparatus having an extrusion device with first and second extruders and a common extrusion die device and a corrugator device with traveling mold jaws, and the extrusion device and the corrugator device being positionally movable in relation to one another for adjustment, wherein the extrusion device is positionally movable in relation to the corrugator device in a horizontal plane a) in that the extrusion device is made movable linearly in a X direction, the X direction extending parallel to a direction of production defined by an axis of the common extrusion die device or extending in line with the direction of production, b) in that the extrusion device is made movable linearly in a Y direction, the Y direction extending transversely to the X direction, and wherein c) the corrugator device is positionally movable exclusively in the vertical direction, wherein the corrugator device is not positionally movable in the X direction or the Y direction, or d) the corrugator device is positionally movable exclusively in the vertical direction and in the Y direction, wherein the corrugator device is not positionally movable in the X direction, wherein the extrusion device has a bearing frame, which is supported on a base frame, the base frame being movable on a first rail device and the bearing frame being movable on a second rail device arranged on the base frame, and wherein the common extrusion die device is exchangeably mounted on an angular stand fixedly installed on the bearing frame and the first and second extruders are mounted to be selectively displaceable along the direction of production on respective first and second rails on the bearing frame.
