A nosebar is supported by supports arranged along the longitudinal direction, and the supports are assembled to fixtures to swing independently of each other in a direction away from a log according to the reaction force of the pressing force acting on the supports. Thus, when a knife peels a knot part of the log or a fragment of the log enters a cutting edge, the portion of the nosebar pressing the knot part or corresponding to the location where the fragment enters the cutting edge is greatly deformed, while the deformation of the nosebar in the other portions is kept small. A corner of the nosebar is prevented from contacting the peeled portion of the raw wood and generating a gap when the nosebar is bent and deformed.

Method for producing a veneer from rattan, veneer sheet, and molded component

A method for producing a veneer in the form of a veneer sheet, wherein the method includes the following method steps: a) providing a plurality of rattan rods having tubules extending longitudinally, b) producing profiles from the plurality of rattan rods, the tubules extending in the longitudinal direction of the profiles, c) connecting the profiles to form a main body, wherein the profiles are arranged within the main body in such a way that the tubules extend in the longitudinal direction and/or transversely to the longitudinal direction and/or at a predefinable angle to the longitudinal direction of the main body, and d) cutting the main body produced in step c), the veneer sheet being obtained. A moulded component is also disclosed.

ELECTRIC VENEER LATHE

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.

VENEER CUTTING AND SORTING APPARATUS
20210178630 · 2021-06-17 ·

A veneer cutting and sorting apparatus is disclosed. The apparatus includes a revolvable knife blade having a cutting edge and a revolvable knife edge receiver having a cutting edge receiving surface. The knife blade cuts a veneer sheet as peeled from a peeler block by a veneer lathe at a previously detected boundary between defective veneer portion and product veneer sheet on the cutting edge receiving surface then revolving at the same peripheral speed as the cutting edge of the knife blade. Cut-off defective portion is allowed to drop off by its own weight.
