Abstract
Abstract A knitted waistband curl-preventing strip is disclosed in which the monofilament stiffener element is knitted into the strip as a part of the courses, but is not inlaid through the outer most lateral wales so that the monofilament stiffener does not extend from lateral edge to lateral edge of the strip. The waistband curl-preventing strip provides soft of flexible edges, and a larger turning radius for the monofilament stiffener which prevents breakage of the monofilament stiffener.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
160 words
A waistband curl-preventing strip, comprising: a knitted strip of a predetermined width, said knitted strip being knitted from polyester or other like flexible yarn utilizing a predetermined number of closed chain stitch wales; a transverse comparatively stiff monofilament inlaid through wale loops substantially transverse to the length of the strip and being positioned within the knitted strip so that it does not extend from lateral edge to lateral edge of the strip, but such that there is at least one wale on each side laterally to the monofilament stiffener; and at least two sets of weft yarns, one set of weft yarns having weft yarns inlaid through at least three wale loops, except at the lateral edges, and then changing direction, the second set of weft yarns having weft yarns inlaid through at least four wale loops, except at the lateral edges, and then changing direction whereby the wales forming the closed chain stitch and the monofilament stiffener are retained.
Claim 2
Dependent Claim
160 words
A waistband curl-preventing strip, comprising: a knitted strip of a predetermined width, said knitted strip being knitted from polyester or other like flexible yarn utilizing a predetermined number of closed chain stitch wales; a transverse comparatively stiff monofilament inlaid through wale loops substantially transverse to the length of the strip and being positioned within the knitted strip so that it does not extend from lateral edge to lateral edge of the strip, but such that there is at least one wale on each side laterally to the monofilament stiffener; and at least two sets of weft yarns, one set of weft yarns having weft yarns inlaid through at least three wale loops, except at the lateral edges, and then changing direction, the second set of weft yarns having weft yarns inlaid through at least four wale loops, except at the lateral edges, and then changing direction whereby the wales forming the closed chain stitch and the monofilament stiffener are retained.
