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.

A method for producing doors or other panel elements having a relief surface comprising the steps of: providing a prefabricated, thin plate member including an only slightly pressed wood fiber or wood chip mass with a content of only partially activated heat-setting binding agent, coating the plate member with paper or veneer, subjecting the thus coated plate member to a non-abrupt pressing between fully covering die pressing plates having a desired matrix-patrix pattern, supplying heat to the plate member during the non-abrupt pressing in such a manner that the binding agent in the plate member as well as in a binding layer for the paper or veneer coating is brought to a final setting subsequent to establishing a final pressing pressure, by which the relief pressing is completed and the plate member generally has been substantially compacted.
