Abstract
A continuous press for a compressible wood-product strand has a row of longitudinally spaced open frames, upper and lower heated press plates extending in a longitudinal direction through and supported by the frames, and respective upper and lower sheet-steel belts having respective lower and upper stretches extending longitudinally parallel to each other through the row of frames between the plates from the upstream to the downstream ends and defining a longitudinally extending passage having an upstream end, a downstream end, and a center between the ends. A drive advances the stretches longitudinally downstream and thereby draws in the wood-product strand longitudinally and compresses it transversely. Two sets of transversely displaceable downstream pressing elements transversely oppositely engageable between the center and the downstream end with the strand between the belts are displaceable longitudinally downstream synchronously with the strand. These pressing elements are urged transversely inward against the strand by actuators provided between the frames.
