TATAMI-FLOOR CUTTING BLADE, TATAMI-FLOOR CUTTING METHOD, AND TATAMI-FLOOR CUTTING DEVICE
To provide a tatami-floor cutting blade, a tatami-floor cutting method, and a tatami-floor cutting device which enable a front face material such as a chain-stitches sewing thread and an unwoven fabric and a rear sheet material to smoothly be rotated, without being turned up by a cutting blade chip blade and without this turned-up part wound around the rotary shaft of the cutting blade, and which prevents a tatami cutting failure.SOLUTION: A tatami-floor cutting blade 10 for cutting a tatami floor 100 comprises: a nearly disk-shaped rotary blade body 14 journaled to a rotary drive shaft and rotated at a predetermined speed; a plurality of curve-profiled projected parts 16 projected at fixed intervals in the circumstance of the rotary blade body 14; and a chip blade 20 arranged on a projected plane 18 of the projected part 16 in a rotation direction A, and is configured to cut tatami in contact with a cutting entrance plane P of the tatami floor 100 to be cut so that the chip 20 may come from a part 14a near from a center O of the rotary blade body 14 and reach a remote part 14b.SELECTED DRAWING: Figure 1
【課題】環縫いされた縫着糸、不織布などの表面材、裏シート材が、裁断刃のチップ刃によって、巻き上げられることがなく、この巻き上げられた部分が、裁断刃の回転軸に巻き付かず、円滑に回転でき、畳床の裁断不良が発生することがない畳床の裁断刃および畳床の裁断方法ならびに畳床の裁断装置を提供する。【解決手段】畳床１００を裁断するための畳床の裁断刃１０であって、回転駆動軸に軸着され、所定の速度で回転される略円板形状の回転刃本体１４と、回転刃本体１４の周縁に一定間隔離間して突設した曲線形状の複数の突設部１６と、突設部１６の回転方向Ａの突設面１８に配置されたチップ刃２０とを備え、チップ刃２０が回転の際に、回転刃本体１４の中心Ｏから近い部分１４ａから、遠い部分１４ｂに至るように、切断される畳床１００の切断入射面Ｐに対して接触して切断されるように構成した。【選択図】図１
