To provide a method for manufacturing a woven fabric for which neither the appearance nor a function provided by flat threads of the woven fabric are impaired, and to provide the woven fabric.

The woven fabric further includes flat threads 3 each wider than a fiber warp thread 10, and the flat threads 3 are caused to pass through healds 102 intermittently with respect to a plurality of the fiber warp threads 10. A hole 102a of each heald is long in a heald moving direction. By causing the flat thread 3 to pass through the hole, the longitudinal direction in transverse plane of the flat thread 3 is oriented along a heald moving direction M. By interweaving fiber weft threads with the fiber warp threads 10, a plurality of woven fabric placement sections is formed so as to be arranged in a weft direction W, each woven fabric placement section being formed as a woven fabric structure and having the flat thread corresponding thereto placed on the woven fabric structure. A flat face HF of the flat thread 3 is disposed on the fiber warp threads 10 in the woven fabric placement section so as to face the fiber warp threads 10. A part of the fiber weft threads is caused to pass over the flat thread 3, to fix the flat thread 3 on the woven fabric placement section. The woven fabric covering section may be formed as a plain weave.

A method of producing a reinforcing fiber woven fabric, for producing on a weaving machine a reinforcing fiber woven fabric from wefts of reinforcing fiber yarns and warps of reinforcing fiber yarns, the method comprising providing, on a weft supply passage for supplying a weft from a weft bobbin to the weaving machine, a weft unwinding means for laterally unwinding weft from the weft bobbin, and a weft storing cylinder body for sucking , along with air, part of weft thus unwound and directed toward the weaving machine and temporarily storing it therein, contactingly supporting weft, minimized in generation of twist by means of lateral unwinding, by a weft contacting means provided in the weft storing cylinder body while being stored in the weft storing cylinder, and preventing the generation of twist of weft being stored by the supporting; a production device therefore, and a reinforcing fiber woven fabric produced therefrom.

An on-machine-seamable papermaker's fabric, which may be produced by modified endless weaving, includes machine-direction (MD) and cross-machine-direction (CD) yarns. When so produced, the MD yarns (24) weave continuously back and forth between the two widthwise edges of the fabric, each time forming a seaming loop (18) at one of the two widthwise edges. Interwoven with at least one of the two sides, top and bottom, of the seaming loops (18) at one or both widthwise edges are at least two additional CD yarns (26). The additional CD yarns (26) interweave with the top and/or bottom of the seaming loops (18) in a leno weave, which keeps the seaming loops (18) in a common position vertically relative to the plane of the papermakers fabric, locks the seaming loops (18) into a desired position and orientation with their planes perpendicular to that of the papermaker's fabric.
