It is provided an apparatus for supporting the erection of a plastics profile during the start-up process of an extrusion line for the extrusion of plastics profiles. An initially bulky profile strand of the plastics profile, which is withdrawn through a calibration unit, can be enclosed by a profile guiding trim of a profile guiding device in front of a caterpillar take-off, wherein the profile guiding trim and/or the profile guiding device can be spatially fixed against a displacement in the extrusion direction in front of an inlet region into the caterpillar take-off and can be shifted and fixed with regard to the vertical and/or lateral position and/or can be rotated about the extrusion direction and be fixed.

Apparatus and method for erecting a plastics profile during extrusion

A calibration device for a calibration, in particular wet calibration of an extrusion device is provided. The calibration device comprises a calibrating element which includes an opening for guiding through a profile produced by means of an extrusion die of the extrusion device and at least one rotatable guide roller which is in contact with the profile when the profile is guided through the opening. The calibration device further comprises at least one separate bearing element insertable into a cutout of the calibrating element, via which the guide roller can rotatably be mounted on the calibrating element.

Calibration device, calibration method and method for manufacturing a calibration device

A calibration device for the extrusion of profiles from plastics is provided. The calibration device comprises at least one tank calibrator with an opening and a running surface for the extruded profile, which can be arranged in a vacuum tank with cooling water and via whose outer surface the heat of the extruded profile can at least partly be transferred to the cooling water. The at least one tank calibrator includes at least one cooling channel for cooling the running surfaces and the axial length of the tank calibrator at least corresponds to the height and/or the width of the nominal dimension of the profile.
