Abstract: The disclosure relates to the treatment of rods made of metal, particularly to the method of reclamation of used standard length rods, such as pump rods already used in the mechanical deep-pumping extraction of oil, as well as to the product made with the help of the mentioned method. The method of remanufacturing of standard length rods includes the reheating of the rod body to a temperature favorable for the plastic treatment of the rod such as plastic deformation of the rod body under pressure. Such methods allow for the reclamation of rods of the desired geometric form and enhancement of the mechanical properties of the remanufactured rod. The technical outcome of the claimed invention consists in the reclamation of rods of the desired geometric form and enhancement of the mechanical properties of the remanufactured rod.

Abstract: A large number of green veneers for plywood respectively having high water contents and formed in a rectangular shape are vertically laminated to obtain a veneer laminate having a quadrangular prismatic shape. The veneer laminate is located between upper and lower platen members so that two opposite side faces of the veneer laminate vertically form cut face gathering planes. The upper and lower platen members are moved toward each other to apply a pressing force to the veneer laminate. The pressing force applied to the veneer laminate is released or weakened while the water drawn through the cut face gathering planes by the pressing force is dripping downward along the cut face gathering planes of the veneer laminate vertically formed.
