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.
