Abstract
Disclosed is a process for the production of synchronous-pore layered materials. Also disclosed is a device for the conduct of the process. In further aspects, the invention relates to layered materials which can be produced by the process, and also to wood-composite boards equipped with the layered materials produced by the process of the invention.
Claims20
A process for the production of synchronous-pore layered materials, comprising the steps of:
- a) producing a layered material, comprising the steps of
- i. printing a carrier material, preferably a decorative paper, by means of digital printing and storing print data and/or positional data of the printed decorative effect;
- ii. drying the printed carrier material;
- iii. applying and drying an impregnation material onto the printed carrier material;
- and
- iv. producing a layered material, comprising pressing the printed and impregnated carrier material together with impregnated core plies and optionally an overlay and optionally a protective layer, with the use of a structure-former;
- b) measuring the dimensions of the structure-former;
- c) measuring the dimensions of the carrier material;
- d) determining deviations of the dimensions of the carrier material from the dimensions of the structure-former;
- e) calculating at least one correction factor K;
- f) communicating the at least one correction factor K to the digital printer;
- and
- g) using the at least one correction factor K for appropriate adjustment of the dimensions of the decorative effect during the digital printing procedure.
10 more elements
A device for the, preferably continuous, production of synchronous-pore layered materials, comprising
- at least one printing line with at least one digital printer for the production of a printed decorative effect on a carrier material;
- at least one means for the drying of the carrier material after the digital printing procedure;
- at least one means for the impregnation of the carrier material and at least one means for the drying of the carrier material;
- a press, preferably a CPL press;
- respectively at least one means for the introduction, to the press, of a printed carrier material, of at least one impregnated core ply, optionally of a structure-former, and optionally of an impregnated overlay, and optionally of a material for the production of a protective layer;
- at least one means for the measurement of the dimensions of the structure-former;
- at least one means for the measurement of the dimensional changes of the carrier material;
- and
- at least one set of control equipment,
- and also optionally
- a means for the roll-up of the layered material produced in a continuous process;
- and/or cutting-to-size equipment for the production of smaller formats.
