Abstract: A multi-axial fabric constructed as a triaxial fabric including oblique warp yarns running of different directions which are interwoven with weft yarns, and straight warp yarns at selected fabric locations interwoven with the weft yarns to form a quart axial fabric. At all of the locations where the oblique warp yarns are crossed with each other, the oblique warp yarns and the weft yarns are interwoven with each other. In addition, the straight warp yarns which are interwoven with the weft yarns are also interwoven with the oblique warp yarns.

Abstract: A weaving machine having opposite arrays of first heddles which are subjected to an alternative weft-wise movement. The weaving machine is also provided with opposite arrays of second heddles which are arranged on one side of the respective arrays of the first heddles adjacent the cloth fell. The weaving machine is operative to manufacture a multi-axial fabric constructed by a triaxial fabric including oblique warp yarns of different direction which are interwoven in weft yarns, and straight warp yarns interwoven with the weft yarns constructing the triaxial fabric. At all of the locations where the oblique warp yarns are crossed with each other, the oblique warp yarns and the weft yarns are interwoven with each other, and the straight warp yarns are interwoven with the weft yarns which are interwoven with the oblique warp yarns.

Abstract: In an apparatus for cleaning a spinning frame provided with a plurality of draft units, a plurality of cleaning units, each provided with an element for creating an air suction force, are disposed adjacent to and below the alignment of draft units in such a manner that each cleaning unit is able to suck flys deposited around a group of the draft units, a main duct is disposed adjacent to and below the alignment of the cleaning units and extended for entire length of the spinning frame, and a filter box is connected to a terminal end of the main duct, each cleaning unit is connected to the main duct, and the main duct is provided with an element allowing a passage of a part of air discharged from each cleaning unit, except at the cleaning unit located farthest from the filter box, whereby the air suction force created by each cleaning unit can be maintained at a uniform value, this apparatus is also provided with an element for cleaning files deposited on the bottom of the main duct, at predetermined intervals
