Abstract

PURPOSE:To simplify the operation in a method for cutting the raw material in the case of single processing of a kneader or the like by automatically measuring width and thickness of the raw material having a square cross section to be fed horizontally and linearly, and computing the full length on the basis of the weight to be processed by the single processing, and deciding a divided length on the basis of the number of pieces appropriate for the single processing, and feeding the raw material on the basis of these data. CONSTITUTION:A rubber material 24 having a square cross section is placed on a roller l horizontally and linearly, and the rubber material 24 is transferred left by the operation of a belt 3, and width and thickness of the material 24 are measured by a shaft measuring body 9 and a thickness measuring body 10. Full length of the material to be processed at one time is obtained on the basis of the weight value to be processed at one time and the measured width and the thickness. The number of cutting time and the cutting length per each cutting are decided on the basis of the number of piece of the material appropriate for the single processing. A motor 18 is driven on the basis of this cutting length to move a movable body 20 left or right to set a distance between the material 24 and a cutting blade 11 at the cutting length. The material 24 is fed to be cut into a predetermined number of piece by the cutting blade 11.
