Abstract: A fin block is provided for a calibrating device for the calibrating of an extruded plastic profile, wherein the fin block includes a back structure and a fin structure having a plurality of fins. The fins are spaced apart from one another and arranged on the back structure in longitudinal direction (L) of the back structure. The back structure of the fin block has a plurality of apertures, the shape and/or arrangement of which within the back structure depends on a predetermined mechanical load capacity for the back structure. Furthermore, a method for the production of the above-mentioned fin block and a calibrating device, which includes a plurality of the above-mentioned fin blocks, is provided. Furthermore, a system for the additive manufacture of the above-mentioned fin block, a corresponding computer program and a corresponding data set is provided.

Abstract: A seal for use in an extrusion device for producing continuous profiles, in particular plastics pipes includes an elastic sealing disc, which is arranged in a plane approximately perpendicularly to the extrusion direction and has a through-passage opening letting through the continuous profile and having a sealing rim bearing against the continuous profile. Connection members are arranged along the sealing rim, and clamping elements are provided for exerting a force on the connection members, with the force acting radially with respect to the extrusion axis. The clamping elements are arranged in a plane parallel to the sealing disc, have a passage opening for the continuous profile and include connecting members for connecting the connection members to the clamping elements.

Abstract: A calibration device for calibrating extruded continuous profiles, in particular tubes, includes a housing and a plurality of segment bodies which are received in the housing in a substantially in circular manner, with axially neighboring segment bodies partially overlapping in a circumferential direction. Each segment body is made from a single-piece workpiece and has a contoured inner surface, wherein the inner surfaces of the segment bodies jointly define a calibration opening for passage of a tube. An operating device retains the segment bodies in the housing and allow adjustment of each segment body in radial direction.

Abstract: An adjustable sizing device for sizing extruded continuous profiles, in particular tubes, includes a plurality of segment bodies disposed about a circle and having a plurality of slats for defining with their radially inner ends a common sizing opening. The segment bodies are held and adjusted in radial direction by actuators to thereby allow change in dimension of the sizing opening, wherein each of the segment bodies is operatively connected to at least one of the actuators. The actuators are received and aligned in at least one mounting ring which has a number of radial bores spaced from one another in circumferential direction at a number corresponding to a number of segment bodies.
