A jump cutting device for use in forming a wooden work piece includes a cutting tool, and a mechanism for moving the cutting tool at an angle between the direction of a crosscut and a direction perpendicular to the cross cut direction. The deepest portion of the cut into the workpiece occurs on a tangent point of the tool. The profile of the cutting tool is a blend of the lineal and cross grain profiles.

A laminated wood product comprising providing a plank presenting a pair of parallel major surfaces, a pair of minor surfaces, a pair of end surfaces and a longitudinal direction parallel with said major and minor surfaces and perpendicular to the end surfaces, said plank having a water content of more than 25% by weight, preferably more than 30% by weight. At least one of the major surfaces is laminated to a surface of a second member.

The present disclosure relates to a method of producing a laminated wood product, comprising providing a plank presenting a pair of parallel major surfaces, a pair of minor surfaces, a pair of end surfaces and a longitudinal direction parallel with said major and minor surfaces and perpendicular to the end surfaces, said plank having a water content of more than 25% by weight, preferably more than 30% by weight, initializing at least one longitudinal crack in the plank, drying said crack initialized plank to a moisture content of less than 20% by weight, and laminating said crack initialized plank by gluing at least one of its major surfaces to a surface of a second member, thus forming the laminated wood product. The disclosure also relates to a laminated wood product, which may be formed according to the method.

A rotary feeder mechanism is provided for a stringer notcher wherein the feeder includes opposing pairs of pusher arms with one pusher arm of each pair being located on opposing sides of a magazine holding a vertically stacked supply of stringers to uniformly move the lowermost stringer onto a work table. The opposing pusher arms are eccentrically mounted on opposite sides of a rotary drive shaft. A control link is connected to each pusher arm to maintain the orientation of the distal ends of the pusher arms in a selected orientation during rotational movement. As one pusher arm moves a stringer onto the work table, the next vertically stacked stringer rests on the top surface of the stringer to be eased onto the bottom of the magazine as the pusher arm retracts below the level of the work table for the opposing pusher arm to then engage the next stringer.

An element with an insertion groove and a dismantling groove. A method for providing a dismantling groove in an element for a product to be assembled by a plurality of elements locked by a locking arrangement including a flexible tongue. The method includes providing an insertion groove and a dismantling groove in the same element. The dismantling groove extends along the element between a first side and a second side and is configured for receiving the flexible tongue of the locking arrangement for locking the element to another element having a tongue groove. The dismantling groove is provided in the element such that it extends from the first side to the insertion groove and along a portion of the insertion groove, and is configured to receive a dismantling tool for dismantling the element from the other element.
