Abstract
PURPOSE:To manufacture the rolled product with uniform thickness without rounding the breadth end parts, by rolling the rolled raw material, after cutting work for forming the breadth end parts of the raw material so as to be thicker than the middle part. CONSTITUTION:The cutting roll 2 for cutting one face of the rolled raw material 1 is installed; and on another side is installed the push roll 3 for pushing the raw material 1 against the roll 2. Behind of these two rolls 2, 3, are installed the cutting roll 4 for cutting the back face of the raw material 1, and the push roll 5 for pushing the raw material 1 against the roll 4. The push rolls 3, 5, are pushing the raw material 1, which has a shape that the middle part is fat and the both end parts are thin, against the cutting rolls 2, 4, so that the breadth end parts of the raw material 1 escape toward the rolls 3, 5, as shown with arrows; hereby, the larger thickness part 6 is formed at the breadth end parts of the raw material 1. After that, the raw material 1 is rolled by the rolling rolls 7, 8; hereupon, the breadth end parts are formed roundly, so that the thickness is not reduced there, and the rolled product 9 with uniform thickness can be manufactured.
