METHOD AND DEVICE FOR PRODUCING A THREE-DIMENSIONAL SURFACE STRUCTURE OF A PRESSING TOOL

摘要

The invention relates to a method for producing a surface structure of a pressing tool, in particular a pressing plate or endless belt, for pressing material plates, plastic films, separating films, PVC surfaces and LVT (luxury vinyl tiles), check cards, passports, credit cards or plastic cards, comprising the following steps:
providing and using digitized data of a 3-D topography of a surface structure,creating digitized data of individual 2-D layers of the 3-D topography,using the digitized data of the 2-D layers to guide a processing head and/or to position it in an x-y plane, or to move a work table in the plane spanned by an x-y coordinate system in relation to a stationary processing head, in order to connect a layer material to an existing carrier material or an already completed layer on the basis of the digitized data of the 2-D layers.

1. Method for producing a surface structure of a large-format pressing tool, having at least one edge length of more than one meter, in particular a pressing plate or endless belt, for pressing material plates, plastic films, separating films, PVC surfaces and LVT (luxury vinyl tiles), check cards, passports, credit cards or plastic cards, comprising at least the steps:
providing and using digitized data of a 3-D topography of a surface structure, creating digitized data of individual 2-D layers of the 3-D topography, using the digitized data of the 2-D layers to guide and/or position the processing head in an x-y plane or to move a work table in the plane spanned by an x-y coordinate system relative to a stationary processing head, in order to connect a layer material to an existing carrier material or an already completed layer on the basis of the digitized data of the 2-D layers,and, independently of a repeating pattern, the surface structure is divided into part-regions which are each sequentially processed or at least partially processed by several processing heads in parallel and/or the boundaries of the part-regions are freely selectable and/or the set part-regions have an edge length of 10 cm to 100 cm, depending on the processing head used.
