  • Patent number: 4812188
    Abstract: To produce doors or other panel elements within the appearance of an infilled panel type, the panelling pattern is achieved through a simple relief pressing of a thin covering plate member which is mounted on a carrier frame work. The covering plate member, coated by a veneer or paper, is produced from wood fiber or a chip mass which is pressed and heated only to the extent that the plate material becomes leather-like, that is, without the incorporated binding agent being hardened. By the relief pressing of the covering plate, heat is supplied in such a manner that the binding agent hardens after the final deformation pressure has been applied, whereby a stable final product is obtained in a simple and inexpensive manner.
