Abstract: Methods and devices for planing ice are described that include at least receiving, at a planing apparatus, an elongate ice ingot, feeding the elongate ice ingot at a configurable rate through an opening in a cutterhead assembly of the planing apparatus, and planing, by the cutterhead assembly, a plurality of surfaces of the elongate ice ingot at a predefined depth as the elongate ice ingot is fed linearly through the opening of the cutterhead assembly. The planing may result in a planed ice ingot.

Abstract: The invention relates to a multi-ply wood product. The supply of wood suited e.g. for the production of plywood has considerably decreased. Consequently, attempts have been made to compensate the deterioration in the quality of the surface finish and in other wood qualities e.g. by means of various coating methods, with varying success. The most important problem has been the insufficient adhesion between the coating and the wood. For the elimination of these problems, a multi-ply wood product has been developed in which at least one layer is formed by a crude fiber ply blank comprising haphazardly oriented fiber material as well as bonding agents, additives and filler materials.

Abstract: A wood-planing and finishing machine in which a cutting tool is secured to a knife stock through a mounting plate. The mounting plate is mounted on the inclined mounting surface of the knife stock in such a manner that the tilting angle of the former, and therefore its vertical position, can be adjusted by means of a wedge member. The degree of projection of the tool increases when the upper end of the mounting plate is tilted upwardly, and decreases when it is tilted downwardly. The mounting plate is secured by the wedge member against tilting and vertical movements resulting from a resisting force acting on the tool during operation.
