A glue applying mechanism of an edge banding machine for applying glue to an oblique surface and a vertical surface of a workpiece includes a base including a glue tub, and a glue applying unit rotatably disposed on the glue tub and including a glue shaft and an obliquely glue applying member connected to the top end of the glue shaft and having a glue applying surface which is a tapered surface with a wide top and a narrow bottom. At least the partial top of the glue shaft and the glue applying surface are exposed outside the glue tub. The glue applying unit is rotatable to extract the glue in the glue tub to the outer surface of the glue shaft and the glue applying surface, enabling the glue to be applied to the oblique and vertical surfaces of the workpiece simultaneously by only one glue applying mechanism.

Construction board is made by first hot-pressing particles in a continuous belt press to form a longitudinally extending, continuous and hot composite strand that is conveyed downstream from the press. Before substantial cooling of the boards and while it is at a predetermined temperature above ambient temperature, an edge of the strand is profiled into a nonsquare profiled contour. Then the strand is transversely severed to form a succession of boards.

Plates (2;) are conveyed continuously in a conveying direction, whereby at least a first edge (15) of a plate Is provided with an edge profile by means of a rotating edge milling tool. A corner (16) connecting, the first edge and a second edge (17) of the plate is rounded at least partly by means of a rotating milling tool (12a, 12b) having a peripheral profile corresponding to a desired corner edge: profile of the plate. The rotating corner milling tool is controlled to be displaced along the continuously moving plate so if) at the rotating garner milling tool moves next to a corner to: he mimdeell and Is subsequently controlled to fee displaced simultaneously in the conveying direction (D) and m a transverse direction to Hie conveying, direction so that if follows a trajectory describing at least a part of: a desired rounding of the corner in a coordinate system fixed to the continuously moving plate.

A round bar cutting device includes a tool rest that is penetrated by a perforation for a round bar to pass through in axial direction. A virtual axis is defined to pass through the radial center of the perforation in the extension direction of the perforation. Four planer tools protrude from the tool rest. The planer tools are spaced apart around the axis as the center. A first edge is formed on one side of the planer tools towards the axis respectively, so as to cut a square bar which moves towards the perforation among the planer tools and rotates round the axis to form the round bar. The cutting device can fully cut the entire section of the square bar in the axial direction into the round bar, and the material utilization efficiency of the square bar is increased.
