A manufacturing cell for producing a three-dimensionally deformable wood veneer, includes a receiving surface for receiving a wood veneer to be processed, and a device for partly or completely separating the wood veneer in order to form veneer strands. The cell further includes a device for pressing the wood veneer to be processed and the veneer strands against the receiving surface. The device is designed to generate a pressure difference between a first side and a second side of the wood veneer to be processed and the veneer strands.

Scarf faces 92a, 92b are machined at a heeling angle .sub.2 on a veneer 90 by adjusting the heeling angle .sub.2 for a desired camber h using the following Equation (1): $\begin{array}{cc}h=\frac{R}{2}.Math.\sin {}_2-\sqrt{{\sin }^2{}_2.Math.\frac{R^2-t^2\left(1+i^2\right)}{4}}& \left(1\right)\end{array}$ With the configuration, double cutting of the veneer 90 by a circular saw 20 can be effectively prevented. Since the camber h is set desirably, the risk can be reduced that the scarf faces 92a, 92b only partially join each other, and a space can be secured to retain an adhesive Ad between arc concavities 91, 91. Thus, when the veneers 90 are joined together at the scarf faces 92a, 92b, the adhesive Ad is unlikely to seep out onto the surfaces of the veneers 90. As a result, the scarf faces 92a, 92b can be properly joined together.

A plywood production work cell utilizes image sensor data to control robot mechanism(s) during an automated veneer stacking operation such that one side edge of each veneer layer is precisely vertically aligned with a corresponding side edge of a lowermost veneer. Each resulting stacked veneer assembly has an aligned side edge that requires minimal post-assembly processing and an opposing non-aligned (jagged, rough) side edge that is abraded/smoothed to produce a plywood panel having a specified width dimension. Selected end edges of at least some veneers are also precisely aligned during the stacking operation and opposing non-aligned end edges are abraded/smoothed to produce plywood panels having a specified length dimension. Each robot mechanism utilizes an end-tool having vacuum grippers arranged in a pair of X-shaped patterns below a horizontally oriented frame, where the image data is generated by cameras mounted on the frame.

Disclosed are a hollow artificial log and a manufacturing method thereof. The method includes: splicing and fixing veneers along a length direction and a width direction, respectively, to obtain a spliced veneer; gluing the spliced veneer on one side to obtain a glued veneer; subjecting the glued veneer to winding and forming around a forming die along a length direction of the glued veneer to obtain a formed body; subjecting the formed body to hot-pressing curing in a hot-pressing die to obtain a cured body; and taking out the cured body from the forming die to obtain the hollow artificial log; wherein an adhesive for the gluing comprises a melamine-urea-formaldehyde copolycondensation resin, and the forming die is a cylinder.
