Abstract
An apparatus for fabricating tubular vanes and adhering the vanes to a plurality of associated ladder tapes for use in a blind assembly for an architectural opening is described. The apparatus includes a first section for unrolling resin impregnated fabric tape, folding the tape, and cutting the tape to a predetermined length. In a second section of the apparatus, the cut and folded tape is bonded to together along its longitudinal edges to form a tubular vane. In the third and final section, the completed vane is positioned between the vertical cords of a plurality of associated ladder tapes and the vane is adhesively bonded to a cross rung of each. After the vane has been bonded to the cross rungs, the ladder tapes are advanced and prepared for receipt of the next vane. The resulting subassembly of vanes is used to fabricate blind assemblies through the addition of headrails and bottom rails.
