Abstract (en)

A warp sizing apparatus includes a first roll on which a warp sheet is to be wound, a second roll positioned around the first roll such that a path of the warp sheet is sandwiched between the first and the second rolls, and a sizing liquid supply device configured to supply a sizing liquid into the nip between the first and the second rolls. The sizing liquid supply device includes a sizing liquid supply pipe having a pipe part extending along an axis direction of the first roll. The pipe part has supply holes that penetrate through a peripheral wall of the pipe part and are formed at intervals in the axis direction. A lowest point in each of the supply holes, which penetrates through the peripheral wall to an inner peripheral surface of the pipe part, is above a lowest point in the inner peripheral surface.
