Abstract
The invention provides an improved planar which effectively prevents undesirable torn grain. The planer of the invention includes at least one planer knife or blade and at least one pressing member, both attached to and supported on a cutterhead. The pressing member includes a head element which is located to have a predetermined angle with respect to the blade and is resiliently movable in a predetermined direction to press an edge of the head element against a certain position of a wood surface immediately before a cutting edge of the blade moving in a fixed direction for cutting or against a boundary between the wood surface and a chip being currently cut from the wood surface. The direct pressing of the pressing member against the wood surface prevents rise of wood fibers and thereby effectively reduces or eliminates undesirable torn or chipped grain.
