A method for manufacturing vertical blinds is disclosed, the method yielding a blind which has curtain material located between the vanes, so that when the blind is deployed across an opening, the vanes may be arranged perpendicularly with respect to the curtain material to allow light into a room or the vanes may be aligned so that they are parallel and overlapping one another, in which case a privacy product results. The method includes preparing discrete pieces of a three component strip having a center portion of curtain material and vane portions bonded to each longitudinal edge of the curtain portion. Adhesive is applied to one or both of the vane portions, and the discrete pieces are placed on an U-shaped mandrel, inverted so that the opening of the "U" faces downwardly. The curtain material portion lies over the rounded top of the mandrel and the vane portion lies against the sides of the mandrel. The mandrel is indexed, another mandrel replaces it and the process is repeated. When the mandrels are indexed, the vanes of adjoining pieces are pressed against one another and are joined by the adhesive. The adhesive employed may be heat activated or be a contact adhesive, and in the most preferred form of the invention, the two vane material portions, when combined with the adhesive, will have substantial rigidity and will be opaque. A novel blind product results from the process.
