PROBLEM TO BE SOLVED: To manufacture diagonal plywood at a low equipment cost and with high productivity.SOLUTION: A plywood board 11 having sides 11a, 11b is sequentially cut along cutting lines 11c inclined with respect to the side 11a and spaced at an interval L to manufacture band-shaped plywood boards 13a, 13b, band-shaped plywood boards 13c, 13d, .... Then while two cutting lines 11c of the band-shaped plywood boards different from each other are positioned on the same straight line, the band-shaped plywood boards are joined at the side 11a or 11b to obtain a joined plywood board 15 or 17, and then the joined plywood board 15 or 17 is cut orthogonally to the cutting line 11c at a suitable interval.

PROBLEM TO BE SOLVED: To obtain a veneer with many cracks or the veneer with few cracks according to requirement even if a material wood is cut by piercing the wood with a thrust piercing body of a driving member. SOLUTION: For obtaining the veneer with less cracks, a first revolving spindle 9 is turned by 180 degrees, and then a piercing roll 27 is raised by 3 mm and kept standby at a raised position. The distance between a top edge of the piercing body 27a of the piercing roll 27 and the top face b of a guide member 6 becomes 4.5 mm as shown in Fig., and the veneer V cut from the material wood 3 is not pierced with the piercing body 27a of the piercing roll 27 even when the veneer passes through the location of the guide member 6, and the crack is hardly formed even if the veneer is got into contact with a peeling face 8a of a peeling member 8.

PROBLEM TO BE SOLVED: To provide a veneer inspecting method capable of detecting a crack having no gap together with a crack having a knothole or a gap without damaging veneer by a simple constitution. SOLUTION: A flaw having breaks like knotholes 3b, cracks 3c and 3d and the like in a veneer structure is inspected by detecting the leak of the irradiation light of the lower luminaire 4, which is provided under the veneer 3 so as to illuminate all over the total length in the fiber direction of the veneer on the way of feeding the veneer in the fiber direction and an orthogonal direction, by the line sensor cameras 5 and 6 provided above the veneer 3, a desired fall is provided to the feed height of the veneer 3 before and behind the inspection lines A of the line sensor cameras 5 and 6 and the own weight of the veneer 3 is put to practical use not only to easily develop the cracks 3c and 3d but also to perform inspection while promoting the leak of the irradiation light of the lower luminaire 4 at the parts of the cracks 3c and 3d.

PROBLEM TO BE SOLVED: To provide a centering method for material wood capable of more exactly calculating a cutting axis and a maximum radius of rotation and to provide its centering device. SOLUTION: A rotation angle of the material wood M is detected with a rotation angle detector 6 engaging with a temporary axis c rotating the material wood M, and a profile used for calculating the cutting axis core and a profile used for calculating the maximum radius of rotation are separately measured. The profile used for calculating the cutting axis is measured at desired positions limited to a plurality of fixed measuring points with reflection-type distance detectors 8 spaced apart at an arbitral distance in the axis direction. The profile used for calculating the maximum radius of rotation is totally measured in a broad area with swing angle detectors 15 each being mounted in each of a plurality of desired measuring areas divided with almost no gap in the axis direction of the material wood M and engaged with a contact-swing type detecting member.

PROBLEM TO BE SOLVED: To improve a yield when a wood block is cut by a veneer lathe. SOLUTION: Even if the wood block W is formed into a small diameter rotated by a disk rotor 111 and cut by a cutter 105 while it is supported by the outer peripheral surface of a first backup roll 27 and the top side end face 61a of a first backup body 61, the first backup body 61 is moved and made to penetrated the space of the adjacent each first backup roll 27 spaced in a direction of a shaft center line of the wood block W, whereby the wood block W is continuously supported by both the members 27 and 61 to make cutting continue, so that veneer Y is obtained.

PROBLEM TO BE SOLVED: To solve various problems caused by a difference in the hardness of raw wood (for example, the deterioration of a peeled skin of a veneer and the damage of a cutter for rotary cutting) when the raw wood is subjected to rotary cutting. SOLUTION: By the use of a veneer lathe 1 for coarse peeling which is provided in front (which is a front in a process and not limited to a positional front) of veneer lathes (2a and 2b) for real peeling, the successively supplied raw wood A is subjected to crude peeling until an indefinite form of it becomes approximately cylindrical. By using a proper hardness determination means (for example, which determines the hardness of each coarsely peeled raw wood A1 on the basis of the amount of electric power required for rotation in the final period of the coarsely peeled raw wood A1), the hardness of each coarsely peeled raw wood A1 is successively determined, and the coarsely peeled raw wood A1 is classified into at least two kinds of hardness and supplied to the veneer lathes 2a and 2b for real peeling having cutting conditions adaptable to each classified hardness.

PROBLEM TO BE SOLVED: To accurately inspect wood with an image having no distortion. SOLUTION: Lighting means 5 and 6 light the wood 9, a plurality of photographing means 8a, 8b and 8c photograph the wood 9 to cause overlap by a desired width, and marker means 12a and 12b radiate a mark of a narrow light beam to a substantially central part in the overlapped photograph region. An image processing means detects a shift amount of the mark position of the images photographed by the photographing means 8a, 8b and 8c from the mark position of reference wood of no distortion, corrects the images photographed by the photographing means 8a, 8b and 8c so as to eliminate the detected shift amount, composites the corrected images photographed by the plurality of photographing means 8a, 8b and 8c, and inspects the wood.

PROBLEM TO BE SOLVED: To provide an inspection method capable of appropriately and speedily inspecting wide articles, even if the position (height) of the inspection surface of a wide article is changed, when the inspection zones of the most adjacent sensor cameras are superimposed on each other by a desired width, in the inspection surface of the wide article for inspecting the wide article through the use of a plurality of sensor cameras. SOLUTION: At the inspection of the wide article 3 through the use of the plurality of sensor cameras 1 and 2, the inspection zone L1 of the adjacent sensor camera 1 and the inspection zone L2 of the sensor camera 2 are set, in such a way as to be superimposed on each other by a desired width N in the inspection surface 3a of the wide article. The center part in the superimposed inspection zones is irradiated with a thin beam of light 6 of a color, which is different from a color originally present in the wide article 3. On the basis of information of the thin beam of light 6 detected by the sensor cameras 1 and 2, the actual range of the superposition of the inspection zones in the inspection surface 3a of the wide article is computed, and superimposed inspection information is processed appropriately and the wide article 3 is inspected.
