SURFACE STRUCTURES ON PRESS BELTS AND PRESS SHEETS

摘要

A method for generating a structured surface of an embossing tool, in particular a press sheet or a press belt, in order to produce surface-structured panel and/or strip material, in which two or more mutually different partial surfaces are structured in mutually time-separated processing sections. Each processing section involving the following steps in the sequence as follows: masking partial surfaces that are not to be structured in the processing section, as long as they are not already masked, with a cover; removing surface material of the non-masked surface in order to produce a surface structure; optionally removing means used to structure the partial surface; and optionally removing parts of the cover or the entire cover. A pressing tool thus produced can produce imitation wooden panels, the optical effect, which comes significantly closer to the appearance of real wooden panels made with conventional pressing tools.

1. A method for producing a structured surface of a pressing tool, such as a press plate or a press belt, to produce surface-structured panel material and/or strip material, wherein two or more mutually different surface portions are structured in mutually time-separated processing segments, each of the processing segments comprising the steps of:
full-surface masking surface portions which are not to be structured in the processing segment and not already masked with a cover, and optionally masking parts of the surface portion to be structured; removing material and/or shaping an unmasked surface to produce a surface structure; optionally removing a means used for structuring the surface portion; and optionally removing parts of the cover or removing the entire cover.
