DEVICE AND METHOD FOR CUTTING RUBBER COATING FIBER SHEET MEMBER

PROBLEM TO BE SOLVED: To provide a device and a method for cutting a rubber coating fiber sheet member capable of cutting to be a smooth cut surface while suppressing the generation and scattering of the cutting waste of a fiber sheet.SOLUTION: In the cutting of a rubber coating fiber sheet member S placed to be flat on a base table 2 while relatively moving a rotary round blade 3 to the sheet member S,: the approach angle A of the rotary round blade 3 to the sheet member S is maintained by a maintaining mechanisms 8 to be a certain angle within 25° or more and 35° or less by rotationally driving the rotary round blade 3; a ratio R/V of the peripheral speed R of the outer peripheral surface of the rotary round blade 3 to the relative moving speed V to the sheet member S of the rotary round blade 3 is 14 or higher and 16 or lower; and then the sheet member S is cut. 【課題】繊維シートの切断屑の発生および飛散を抑制しつつ、滑らかな切断面に切断することができるゴム被覆繊維シート部材の切断装置および方法を提供する。【解決手段】ベース台２に平置されたゴム被覆繊維シート部材Ｓを、回転丸刃３をシート部材Ｓに対して相対移動させながら切断するに際して、回転丸刃３を回転駆動して、維持機構８によってシート部材Ｓに対する回転丸刃３の進入角度Ａを２５?以上３５?以下の範囲内の一定角度に維持するとともに、回転丸刃３の外周面の周速度Ｒと回転丸刃３のシート部材Ｓに対する相対移動速度Ｖとの比Ｒ／Ｖを１４以上１６以下にしてシート部材Ｓを切断する。【選択図】 図３
