PURPOSE:To cut a slit on the vertical piece of an L shaped plate, to easily execute the chamfering caused on a front end face in a short time simultaneously without by a manual work and to improve the productivity. CONSTITUTION:A 1st wire wheel rotated by a rotation driving means is pressed to the front end face of a vertical piece via a pressing spring by a 1st air cylinder for advance and retreat, and chamfering is executed with the 1st wire wheel part being subjected to the combination motioning of the ascent and lateral movement by a 1st air cylinder for lifting and lateral feeding means. Simultaneously, the 2nd wire wheel rotated by a rotation driving means is abutted on the inner end face of the vertical piece by the 2nd and 3rd air cylinders for pressing, the 2nd wire wheel is pressed to the above inner end face via the 3rd air cylinder for back pressing by the 2nd air cylinder for advance and retreat and chamfering is executed with the 2nd wire wheel being subjected to the combination motion of ascent and lateral movement by the 2nd air cylinder for lift and lateral feeding means. |
