Title:
VENEER LATHE
Document Type and Number:
Japanese Patent JP3665162
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To enable cutting of material wood to a small radius by a veneer lathe which has a simple structure and of which the maintenance and control are easy.
SOLUTION: In a veneer lathe, a holder 31 moving forward and backward is provided at a position opposite to a plane block 4 which is provided with a rotary roll provided and driven at a position being parallel to an edge line of an edge tool 2 and coming into contact with the peripheral surface of material wood 1, and others, and the holder 31 is provided with a pair of parallel rolls 31 and 38 which have the centers of rotation at positions being apart by prescribed equal distances from the direction being parallel to the direction of movement of the holder and intersecting perpendicularly a virtual line passing through the center of rotation of the material wood. In a state wherein the material wood 1 is supported by a pair of spindles S, cutting is conducted by moving the plane block 4 and the holder 31 toward the spindles at the same speed in accordance with the number of revolutions per unit time of the material wood obtained from a revolution number measuring mechanism, and a control is made so that the paired spindles S be operated to withdraw according to a signal generated on detecting that the radius of the material wood becomes a prescribed amount set beforehand, in the process of cutting, and that the movement of the plane block 4 and the holder 31, in contrast, be continued still thereafter.
