ゴムホースSが切断刃21によって圧潰され、この結果、
第3図に示すようにゴムホースSの切断面Saが平らにな
らず、歪みを生じるという問題点があった。However, in this cutting device, since the rubber hose S is cut by so-called push cutting, the soft rubber hose S is crushed by the cutting blade 21 at the initial stage of cutting, and as a result,
As shown in FIG. 3, the cut surface Sa of the rubber hose S is not flat, and there is a problem in that distortion occurs.
前記事情に鑑み、第4図(a),(b)に示すように、
三日月形の切断刃31をモータ32の回転軸にクラッチ33及
びブレーキ34を介在して固着し、該切断刃31を間欠的に
