Foreign substance removing device for sheet material, sheet material manufacturing device, and sheet material manufacturing method

Abstract

A foreign substance removing device for a sheet material includes a gas injection mechanism disposed away from a surface of a sheet material from which a foreign substance is to be removed, the foreign substance removing device removing the foreign substance by injecting gas toward the sheet material from the gas injection mechanism. The gas injection mechanism includes an injection hole unit including a pair of a first injection hole and a second injection hole, each of which injects the gas toward the surface of the sheet material, and in a cross section including central axes of the first injection hole and the second injection hole, extended lines of inner ridgelines of the first injection hole and the second injection hole are inclined so as to intersect with each other at a position away from the surface of the sheet material toward the gas injection mechanism.
