PURPOSE:To shorten a cutting cycle time by a method wherein a sizing machine is waited before the sizing position and a material to be worked is collided against a stopper to align the fore end of the material. CONSTITUTION:The material 1 collides against the stopper 6 at waiting position with a regulated low speed and pushes the sizing machine 4. The sizing machine 4 moves to the proceeding direction of the material 1. In a condition that the number of pieces of the material 1 is few, the moving speed of the sizing machine 4 becomes slow and the non-contacted material 1 arrives at the stopper 6 quickly and the aligning of the fore ends of the material may be effected in a short period of time. In second stage, the sizing machine 4 is controlled so as to stop at the sizing position E and the materials are stopped forcibly in accordance with the stop of the sizing machine, thus, the aligning work of the fore ends of the material may be finished. |
