Zusammenfassung:	PCT No. PCT/FI94/00199 Sec. 371 Date Feb. 15, 1996 Sec. 102(e) Date Feb. 15, 1996 PCT Filed May 17, 1994 PCT Pub. No. WO94/26485 PCT Pub. Date Nov. 24, 1994The invention is related to a method and apparatus for compressive shape-drying of wood (1). In the first phase of the method, green wood is compressed to a desired shape simultaneously heating the wood. According to the invention, during the first phase the wood (1) is compressed against gas-permeable surfaces (3, 4) rapidly to a desired and thickness. during the second phase of the compression process, the compression pressure is lowered to a level causing a thickness reduction equal to or greater than the thickness reduction caused by the drying of the wood, and the internal temperature of the wood is lowered with the progress of the compression process.
