ABSTRACT:
A method and apparatus for forming a pleated cellular shade product from a single web of material to provide different physical characteristics on opposite sides of the shade product. A web is provided having alternate first and second stripe areas extending crosswise of the web at a preset repeat spacing and the striped web is folded crosswise of the web alternately in a first direction along a first fold line intermediate side edges of the first stripe area and in a second direction along a second fold line intermediate side edges of each second stripe area to form a plurality of sidewise adjacent panels serially united in alternate succession along respective first and second fold lines. Faces of sidewise adjacent panels that are united along the first fold lines are joined in a first band spaced from the associated first fold line a distance greater than one-half the fold spacing and within the second stripe areas, and faces of sidewise adjacent panels that are united along the second fold lines are joined in a second band spaced from the associated second fold line a distance greater than one-half the fold spacing and within the first stripe areas.
