Title:
原木の切削方法およびベニヤレース
Document Type and Number:
Japanese Patent JP6654425
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To form a thickness of cutting veneer almost constant, even when a construction material of raw wood is different, in cutting of the raw wood by a veneer lathe in a state of separating a spindle S from the raw wood.SOLUTION: A size of force of operating on a second backup roll 73 from raw wood W in cutting and of pressing in the direction orthogonal to a virtual line Z-Z and going away from a rotational center O, is measured by a force sensor 88, and when the size of the measured force is smaller than an allowable range, frictional force is continuously increased to rotation of the raw wood W until the size of the measured force becomes the allowable range from a first backup roll 31 by operation of a torque motor 53, and when the size of the measured force becomes the allowable range, an increase is stopped so as to be set as constant frictional force.SELECTED DRAWING: Figure 5
