An apparatus for moving veneer includes a leaf spring having at lower tip end thereof sharpened edges and configured to move a veneer sheet toward its preceding stationary veneer sheet. Further lowering the leaf spring with the tip end already stuck in the veneer sheet causes the leaf spring to be resiliently deformed, which creates a force due to restoring force of the leaf spring that acts on the veneer sheet to move toward the preceding veneer sheet thereby to reduce or eliminate a gap between the two veneer sheets. Additional leaf spring movable with the above leaf spring and configured to hold the preceding veneer sheet during the movement may be provided.

The present invention relates to an adhesive thread device for producing an adhesive thread, comprising a supply means for supplying an adhesive-free crude thread, an adhesive tank for receiving and storing an adhesive granulate, a main heater arranged at a lower portion of the adhesive tank to define an activation zone of the adhesive tank in which the adhesive granulate is surface-melted, a closed receptacle substantially horizontally arranged, which is arranged at the activation zone of the adhesive tank with a first end, wherein the closed receptacle comprises at least one inlet opening for supplying, and at least one outlet opening for withdrawing the crude thread, and wherein, when passing the crude thread through the closed receptacle, the crude thread is wetted with adhesive on its entire outer surface in an oxidation-free manner. Furthermore, the present invention relates to a device for joining workpieces as well as a method for producing an adhesive thread and a method for joining workpieces.

Scarf faces 92a, 92b are machined at a heeling angle θ.sub.2 on a veneer 90 by adjusting the heeling angle θ.sub.2 for a desired camber h using the following Equation (1):

[00001]$\begin{array}{cc}h=\frac{R}{2}.Math.\sin {\theta }_2-\sqrt{{\sin }^2{\theta }_2.Math.\frac{R^2-t^2\left(1+i^2\right)}{4}}& \left(1\right)\end{array}$

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 structural reinforced composite construction mat includes a plurality of composite plastic beams that are ganged together to define the mat, with a plurality of flitch plates disposed between at least some of the plastic beams to provide additional strength and rigidity to the mat. The plastic beams may be made of a composite material have a generally rectangular cross-section. The flitch plates have a width (vertical height) when disposed between adjacent beams that is less than the width (vertical height) of the beams, such that the flitch plates may be recessed below and above the top and bottom surfaces of the mat, respectively. A plurality of rods extend in the lateral direction through the beams and plates to compress the beams and plates against each. The flitch plates may be metal or fiber-reinforced resin and may further include slotted holes to allow the beams to retract lengthwise in response to environmental changes.
