Embodiments of an electric linear actuator may include a roller screw assembly, an electric motor coupled to the roller screw assembly, and a linear transducer operatively coupled with the roller screw assembly. The motor may be configured to drive the roller screw assembly to extend and retract another component, such as a rod. In some embodiments, the linear transducer may be configured to detect a position of the rod. The roller screw assembly may be coupled directly to the motor via a gear coupling, with the motor disposed generally in axial alignment with the roller screw assembly. Other embodiments disclosed herein include a veneer lathe carriage with electric linear actuators and corresponding apparatuses, methods, and systems.

The present invention relates to a method of producing wooden components, wherein in the method a first wooden slat is provided with an adhesive at at least one of its planar broad sides and/or at at least one of its narrow sides and the first wooden slat is glued to a second wooden slat to form a block of a plurality of wooden slats, wherein at least the first wooden slat is in a wet state during the gluing.

An edge band cutting device includes a base reciprocated along a direction parallel to a conveying path between a front cutting position and a rear cutting position, a baffle component disposed to the base and having a baffle configured to be reciprocated along a direction parallel to the conveying path between an initial position and a compression position, and reciprocated along a direction perpendicular to the conveying path between a lifting position and a lowering position, and a cutting component disposed to the base and having a saw blade configured to be reciprocated up and down along a cutting path perpendicular to the conveying path. By operation of the baffle component and the cutting component, only one saw blade is used to cut a front protrusion and a rear protrusion of an edge band, such that the structural design is greatly simplified.

A structure can be formed by wrapping one or more densified, lignin-compromised wood veneers wrapped around a central axis. The wrapped wood veneers can form a circumferentially-extending wood wall. A glue can be provided on one or more surface portions of each wood veneer. The wood veneers can be lignin-compromised by in situ lignin modification, partial delignification, or full delignification. The circumferentially-extending wood wall can form a hollow member, for example, a tube, pipe, cup, tank, or bottle. Alternatively, the circumferentially-extending wood wall can surround a central member, for example, to form a rod, bat, club, or dowel.
