Claims

[Claims for Utility Model Registration] (1) A plurality of rotary grindstones each having a grindstone surface on their end surfaces are arranged on the movement path of the cloth cutting knife with their phases shifted so that the end surfaces face the movement path of the knife, A cutting edge grinding device for a fabric cutting knife, in which the end faces of each grinding stone are inclined in a direction in which one end intersects and the end faces of each grinding wheel are inclined in a direction that moves away from the intersection when viewed from the direction of movement of the knife. (2) The end face of the rotating whetstone is tilted in a direction opposite to the direction in which the knife moves, and the whetstone surface on each end face is tilted at an angle equal to the above inclination from the center of the whetstone toward the outer periphery. 2. The cutting edge grinding device for a cloth cutting knife according to claim 1, wherein the cutting blade has an inclined surface. (3) The cloth cutting knife according to claim (1) or (2), wherein the rotating whetstone and the whetstone surface are formed from a synthetic resin ring that covers the whetstone body, and a sheet-like file that is adhered to the ring. Blade grinding device.
