ABSTRACT:
A frangible connection for connecting parts of a knitted textile into a single panel is disclosed. The frangible connection is formed of a yarn having a lower tensile strength than that used to knit the parts of the panel so that the parts can be readily disconnected by tearing the frangible connection without damaging the structure of the parts themselves. Thus, a plurality of vertical blind louvers may be knitted into a single panel on a single knitting machine and separated later, preferably prior to installation. Knitted patterns which extend across multiple louvers may thus be practically manufactured without the difficulties in alignment which might be present if each louver were manufactured separately. The frangible connection also functions as a hinge for pivotably connecting the louvers of a combination blind together. The combination blind may consist of alternating opaque louvers and sheer spacers which may be pivoted relative to each other to achieve varying levels of light transmission through the blind.
