Title:
FABRIC WITH WOVEN MARKERS
Document Type and Number:
WIPO Patent Application WO/2008/143557
Kind Code:
A8
Abstract:
Markings visible by automatic optically guided cutting equipment are provided in a fabric such as a double layer fabric for one-piece-woven air bags by groups of black marker weft yarns (16) which contrast with the other (white) weft yarns (20) and warp yarns (18). The marker weft yarns emerge onto the upper face of the fabric only in predetermined marker areas (10) spaced apart in the warp direction by other white weft yarns to afford optically identifiable markings spaced apart along said weft yams and spaced apart along the direction of the warp yarns. The arrangement avoids the need for black warp yarns and thus avoids the inconveniences and loom down-time associated with required alterations to the locations of such optically detectable marker areas in the fabric web.
