PCT No. PCT/BE94/00067 Sec. 371 Date Jun. 27, 1996 Sec. 102(e) Date Jun. 27, 1996 PCT Filed Oct. 12, 1994 PCT Pub. No. WO95/10423 PCT Pub. Date May 20, 1995A method and an apparatus for manufacturing decorative panels with relief decorations on at least one of the broad sides of the panel are described. In a chamber, a hard, at least partly thermoplastic resin foam sheet with an essentially closed cell structure is substantially evenly heated on at least one of its broad sides, such that it becomes soft. Then, by means of a mould, the decorations in raised and/or sunken relief are applied to at least one of the broad sides by pressing.
