Application No. 08/243,000
said strip on the opposed face thereof; cutting said strip
into a plurality of cut strips of uniform length; feeding each
cut strip to a position juxtaposed to the said first sheet
with each said cut strip extending transversely to said first
sheet, positioning said first sheet relative to each said
strip as said strip is fed thereto thereby to position said
strips in overlapping relation, adhesively tack bonding said
cut strips to said first sheet in said overlapping relation
with said one marginal portions thereof in closely spaced
apart relation longitudinally of said first sheet;
continuously feeding a second sheet of material in juxtaposed
coincident longitudinal and transverse relation with said cut
strips and said first sheet and in contact with said opposed
marginal portions of said cut strips; pressing together said
first and second sheets with said cut strips therebetween; and
adhesively bonding said cut strips and sheets to produce a
cellular structure in which said first and second wide sheet
materials are relatively movable in directions perpendicular
to said cut strips to produce a window covering in which said
strips selectively produce a closed window covering or an open
window covering.
133. A method for manufacturing a fabric light control
window covering, comprising continuously supplying a narrow
strip material and feeding said strip material longitudinally,
said strip material having first and second edges and first
and second sides; applying a first adhesive line
longitudinally to said strip material adjacent said first edge
on said first side; applying a second adhesive line
longitudinally to said strip material adjacent said second
edge on said second side; feeding a first wide sheet material
longitudinally in a direction transverse to said strip
material; cutting said strip material into a plurality of
individual cut strips having a length substantially equal to
the width of said first wide sheet material; pressing said
first side of each said cut strip along said first edge
against said first sheet material to tack bond each cut strip
along said first adhesive line thereon to said sheet material;
displacing each cut strip partially away from said first wide
sheet material before tack bonding the next successive strip
thereto; feeding a second wide sheet material into contact
with said second sides of said cut strips bonded to said first
