Abstract: To make coincide cutting centers of two end surfaces of raw wood with the axis of spindles of a veneer lathe, at least two axial corrections which are performed in a state in which the raw wood is held by centering spindles are required. Conventional apparatuses suffer from too complicated structures and enlargement of the cost because of the complicated structures. A correction operation of an axial direction of correction operations in the two axial directions is performed such that only a movable centering spindle is moved in a direction intersecting a direction in which holding arms are extended/contracted. Another correction operation in another axial direction is performed by extending/contracting the holding arms.

Abstract: A base plate for mounting a router in a support table provides a plate configured to fit in an orifice, having an inwardly extending ledge thereabout, defined in the support table with the router supported by the base plate to depend therefrom. The base plate defines a medial orifice for passage of the router shaft through the orifice for operative positioning of a cutter carried on the router shaft above the base plate. The base plate medial orifice releasably carries plural annular inserts to cover space between the router shaft and the support plate portion defining the medial orifice. Plural adjustment screws are carried in threaded engagement in the ledge of the support surface orifice for vertical motion to adjustably move adjacent portions of the base plate periphery upwardly from the ledge to create a coplanar relationship of adjacent portions of the base plate and support table.

Abstract: The present invention facilitates the fabrication of an unlimited variety of dovetail joints without the use of standardized template devices. Additionally, the device is capable of supporting a workpiece on both sides of the router bit cutting edge and adjusting the angular orientation of the guiding fence in relation to the axis of directional translation. The device is comprised of a router table and a slideably coupled positioning apparatus. The router table comprises a tabletop and means for securing a router so that the router's cutting bit extends upwardly through a central orifice. The upper surface of the router table has two longitudinal guide grooves which are parallel to one another and equally spaced on opposite sides of the central orifice. The positioning apparatus is comprised of a guide fence unit with two pivotally secured parallel runners.

Abstract: Solid carbide segments are brazed to the rim of a steel body and then teeth are ground into them. This allows more teeth/inch on the perimeter and larger diameter blades than on previous carbide-tipped blades. The segments, which typically form an arc of a circle, provide the improved performance of carbide blades without excessive expense of solid carbide blades.

Abstract: Disclosed herein is a new kind of veneer which has the cross grain (such as wavy grain and interlocked grain) artificially formed on the surface of straight-grained veneer cut by quarter sawing from a species of wood which should yield the cross grain but actually has no cross grain. Disclosed also herein is a method of producing the cross-grained veneer, said method comprising cutting wood into veneer of desired thickness which assumes the straight grain, by using a veneer peeling machine equipped with a knife whose cutting edge waves continuously in the lengthwise direction, and flattening the veneer having an uneven surface by means of thermal fixing or hot pressing, thereby artificially forming the cross grain on the surface of the straight-grained veneer. The knife is constructed such that the cutting edge waves in the widthwise direction of the knife and the troughs of the wave are disposed along the straight line extending in the lengthwise direction of the knife.

Abstract: A method and apparatus for improved centering of a workpiece in a planer machine includes centering sectional shoe assembly positioned in close proximity to opposed cutting heads, between the cutting heads and a centering feed assembly. The shoe assembly includes a plurality of individually movable pressure shoe sets, comprising an upper shoe and a lower shoe. Each shoe set is operatively connected to a closed circuit, double rod end hydraulic cylinder assembly which selectively and independently positions the shoe set responsive to the surface to the workpiece. A pressure device is also operatively connected to each shoe set to provide a centering force. In use, as the upper or lower shoe of a shoe set is forced away from the centerline of the workpiece, the opposing shoe would automatically move the same amount. The shoe assembly thus centers each and every workpiece independent of the amount of stock removal required.
