Abstract: The disclosure provides a method for separating scrap produced during the manufacture of extruded sheets, wherein an extrudate of an extruder is fed to a calender comprising a plurality of temperature-controlled calender rollers, an actual temperature of at least one calender roll is measured, the actual temperature is compared with a nominal temperature provided for this calender roller, and in the case that a difference between the actual temperature and the nominal temperature lies outside a predefined tolerance amount, a part of an in particular endless semi-finished product exiting the calender is discharged as scrap. By treating that part of the semi-finished product which has been exposed to the wrong temperature as scrap, it is particularly easy to identify sheets that do not meet the desired quality requirements essentially without additional measuring effort, so that it is possible to easily discharge scrap produced during the manufacture of extruded sheets.

The disclosure also relates to a decorative panel, which comprises a carrier plate, at least one decorative layer, at least one laminating adhesive layer and an antiwear film according to the disclosure, wherein the antiwear film is arranged with its carrier film facing the carrier plate, and wherein the decorative layer and the laminating adhesive layer are located between the carrier plate and the thermoplastic carrier film.

Abstract: A production line for manufacturing extruded plates, comprises a conveyor for conveying a semifinished product, an edge cutting device for cutting off an edge area of the semifinished product to present a plate-shaped endless base profile, and a separating device for separating individual plates from the endless base profile. A distance (D) between the separating device and the edge cutting device in the conveying direction is dimensioned such that, between an average temperature T1 of the semifinished product during cutting of the edge area in the edge cutting device and an average temperature T2 of the endless base profile during separation, there is a temperature difference T1?T2 of 2 K?T1?T2?15 K. Due to distance (D) within an optimum temperature range, further processing of the cut off edge areas is essentially neutral in terms of installation space.

Abstract: A method for starting up a production line for manufacturing extruded plates, wherein an extruded semi-finished product comprising a free end is pressed towards a conveying device, wherein the conveying device is configured to pull the semi-finished product to a separating device, wherein a conveyor belt extending in the conveying direction is placed on the conveying device, the free end of the semi-finished product is pressed onto the conveyor belt, the conveyor belt is pulled together with the semi-finished product towards the separating device, and the free end of the semi-finished product arriving at the separating device is introduced into the separating device, while the conveyor belt is pulled away from the semi-finished product upstream of the separating device. This enables a cost-effective production of panels made from the plates.

Abstract: The present disclosure relates to a decorative panel with a carrier plate comprising a multi-laminate plastic carrier material with a plurality N of layer sequences of the A-B-A type, wherein layer A comprises a first thermoplastic resin and layer B a second thermoplastic resin different from the thermoplastic resin of layer A and wherein N lies between ?3 and ?250.

Abstract: The present disclosure relates to a method for producing a decorative wall- or floor panel, having the method steps: • a) providing a melted polymer mass; • b) extruding the molten polymer mass through a nozzle; • c) finish-sizing the molten polymer mass to form a panel-like carrier material by means of an assembly of multiple rotatable rolls, wherein the individual rolls are disposed one above the other or one behind the other and each individual roll forms at least one finish-sizing nip with neighbouring rolls, through which nip the melted polymer mass is passed, and wherein the finishing nip heights can be variably adjusted by a horizontal and/or vertical movement of individual rolls during the production process; • d) applying a decor pattern that imitates a decor template to at least one sub-region of the at least partly finish-sized carrier material, and • e) applying a protective coating to at least one sub-region of the decor.
