Abstract
A method for producing a blank of a slab-like product, in which method a fibrous material such as chips or the like is mixed with a binder material such glue, cement or the like, and the mixture is fed into a blank-forming apparatus. The method is implemented by feeding the mixture of fibrous and binder materials from the blank-forming apparatus to a conveyor or similar platform in order to form a blank, after which one or more layers of blank-separating material is dispersed layer by layer onto the blank, and finally a second blank is laid onto the layers of blank-separating material.

A method for producing a blank of a slab-like product comprising the steps of:
- mixing a fibrous material with a binder material;
- feeding the mixture from the blank-forming apparatus to a conveyor to form a first blank;
- dispersing at least one layer of blank-separating material on the first blank on the conveyor;
- feeding the mixture of fibrous material and binder material onto the at least one layer of blank-separating material on the first blank on the conveyor to form a second blank;
- and
- separating the first blank from the second blank along that at least one layer of blank-separating material to form at least two individual blanks.
A system for producing a slab-like product blank, said system comprising at least two blank-forming apparatuses, each apparatus being equipped with at least one rotating blank-shaping unit having a surface of rotation carrying dispersing elements and an underside of the apparatuses being equipped with a conveyor for forwardly transferring a mixture of fibrous material and binder material, the system further comprising a blank-carrying platform under each of the blank-forming apparatuses and a dispersion unit between the blank-forming apparatuses, the blank-carrying platform receiving the mixture from a first apparatus then receiving blank-separating material from the dispersing unit and then receiving more mixture from a second apparatus whereby the blank-carrying platform has a first and second blank formed therein with the blank-separating material thereinbetween, the blank-carrying platform therefore having at least two blanks thereon which are separable at the blank-separating material to from at least two individual blanks, the blank shaping units having an adjustable surface of revolution.
