The invention relates to an oblong wooden construction and a roller press for producing the construction. The wooden construction consists of four pieces 31 which are joined and extend from one end to the other in the construction, these pieces having uniform dimensions in both the transverse and the longitudinal direction and an essentially rectangular cross section, and the joint surfaces on these pieces being provided with joint grooves 32 and corresponding tongues 33. The roller press comprises at least one unit of four rollers, in which the axes of rotation 5, 6, 7, 8 of all four rollers 1, 2, 3, 4 are located in a plane at right angles to the longitudinal direction of the object to be pressed. <IMAGE>
