Document Type and Number:
WIPO Patent Application WO/2005/080651
Kind Code:
A1
Abstract:
Disposed on the back of a modified reed (12) forming a weft guide passage (121) is a nozzle forming body (31) provided with a stretch nozzle (312). A passage forming body (39) provided with a weft arrest passage (38) is disposed in front of the modified reed (12). The position where the passage forming body (39) is disposed can be changed along the guide passage (121). At least a part of the arrest passage (38) extends in a direction intersecting the direction of extension of the guide passage (121). The weft tension device thus arranged can cope with changes in woven width without incurring degradation of fabric quality and can impart sufficient tension to the weft.
