A method for forming grooves in a board element. An exemplary method includes arranging the board element in contact with a support member, and forming at least one groove in a rear side of the board element by removing material, such as chips, from the board element by rotating one or more cutting devices including a plurality of tooth elements configured to rotate around a rotational axis. A method further includes counteracting, such as preventing, a displacement of the board element away from the support member during forming of the at least one groove, wherein the counteracting, such as preventing, includes arranging at least a portion of the board element between an obstruction element and the support member.

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.

A device for machining material includes a rotatable turret including a plurality of plank holding positions, each plank holding position including a plank holding device. A projector is configured to project at least one cut line on a first surface of a plank. A cutting device is positioned adjacent to the turret, the cutting device includes a cutting tool configured to cut a trim section along a second surface of the plank to establish a substantially planar portion and/or to locate defects of the first edge. A sensor is configured to scan the first edge of the plank and determine whether the groove and the substantially planar portion are within a predetermined tolerance. A jointing device is positioned adjacent to the turret, the jointing device includes a joint cutting tool configured to cut at least one groove on the second surface.

The present invention provides a jig for fabricating a concave-convex structure. The jig for fabricating a concave-convex structure is coupled to a multipurpose woodworking device including a woodworking work table for performing a plurality of operations for forming a concave-convex structure and a router mounted on the woodworking work table to perform the operations for forming a concave-convex structure, using a plurality of end mills. Furthermore, the jig for fabricating a concave-convex structure includes at least one of a wood piece support jig supporting or fixing a wood piece to be fabricated, a shaping guide jig allowing for forming shapes corresponding to the operations for forming a concave-convex structure, and a stopper jig maintaining X-axial movement of the router by intervals corresponding to the operations for forming a concave-convex structure. Accordingly, it is possible to easily fabricate circular, round, rectangular, dovetailed, and gallery-shaped grooves and joints.

The invention relates to a simple and safe method for manufacturing a wood part joint, in particular a cross-laminated timber for a house wall, from a plurality of individual layers which are laid as longitudinal layers (L) and transverse layers (Q) at an angle to one another and subsequently joined, preferably glued and pressed, at their mutually facing main surfaces. According to the invention, at least the boards of the longitudinal layer (L) are pre-fixed in their transverse direction using an elongate string element (2) at least in the end region, in particular using beading pressed into a groove. The invention also relates to a corresponding device for carrying out the method, wherein a feed for the elongate string element (2) is provided which can independently also be used for a wood part joint in which abutting, shorter pieces of wood are pre-fixed in the longitudinal direction to a board.

An adjustable pocket-cutting device includes a worktop supporting a workpiece, an actuation lever assembly including an actuation lever pivoting about an actuation lever pivot and configured to support a router having a router bit such that the router bit sweeps through a slot in the worktop and into a workpiece as the actuation lever pivots from a retracted position to a deployed position, and a stop assembly for adjustably limiting pivotal movement of the actuation lever to the deployed position. The stop assembly includes a stop lever adjustably mounted relative to the worktop and a stop member extending from the stop lever across or through the actuation lever, wherein the stop member abuts against an abutment surface of the actuation lever to adjustably limit the movement of the actuation lever to the deployed position.

A bearingless groove router bit includes at least one cutting element affixed to a head of the router bit and has a first end spaced from an end of connected shank connected to the head and a second end adjacent to the second end of the head. The cutting element includes a cutting edge extending along the cutting element between the first end to the second end of the cutting element. The cutting edge may include a radial side edge that projects radially inwardly relative to a central axis of the router bit and a straight side edge that extends from an end of the radial side edge outwardly relative to the central axis to minimize tear out during cutting of a groove in a work piece.
