Abstract:
An apparatus for fabricating a hollow tubular vane for an architectural covering device wherein said covering device includes a plurality of elongated vanes operatively interconnected by a vane control system comprising in combination;a supply roll of sheet material having longitudinal side edges,a system for advancing said sheet material along said apparatus,an adhesive applicator adapted to apply a bead of adhesive along at least one of said side edges of said sheet material, said bead of adhesive covering an imaginary line spaced inwardly a short distance from said at least one side edge,a folder adapted to progressively fold the longitudinal side edges of said sheet material until the side edges are adjacent to each other, and the sheet material is in a hollow tubular configuration,a compressor adapted to compress said longitudinal side edges together along the bead of adhesive and said imaginary line so as to define a flap along each longitudinal side edge, at least one of said flaps having said bead of adhesive thereon, anda cutter for cutting the folded tubular first sheet of material into preselected lengths defining said vanes.
