A method and apparatus for forming expandable-collapsible articles comprises a horizontally oriented frame which receives one or more webs of sheet material from a feeding mechanism, a pusher bar having upper and lower gripper members engageable with the sheet material and a stripper bar having upper and lower stripper members movable between folding position and discharge position with respect to the frame. One or more linear actuators are provided to move the pusher bar toward and away from the stripper bar, and the extent of linear movement of such actuators is adjustable so that different lengths of sheet material can be advanced by the pusher bar into contact with the stripper bar thus forming fold lines in the sheet material with varying spaces therebetween. An expandable-collapsible product is formed having an accordion fold configuration with an outwardly facing surface of essentially any desired contoured shape, or, alternatively, cellular articles are formed consisting of a series of side-by-side, elongated hollow cellular units which are formed by the same elements used in fabricating accordion folded articles, with the addition of adhesive dispensers and welding units.

A method and apparatus is provided for forming a window treatment article having opposed upper and lower sheets interconnected by transversely oriented, longitudinally spaced vanes comprising a pair of counter-rotating folding rollers oriented with respect to one another to form a nip therebetween, and a pusher bar assembly which is operative to successively advance a portion of the upper sheet into the nip between the folding rollers where it is folded and brought into contact with a lower sheet. The upper sheet is successively folded upon itself to form a number of transversely-extending, longitudinally-spaced vanes each having a fold line defining an inner end which is affixed to the lower sheet, and an opposite, outer end which is closed by adhesive attachment, an ultrasonic weld or other means of attachment, thus defining an essentially closed pocket having opposed sides within which a rectangular slat can be removably inserted to add overall rigidity to the finished article and to provide a decorative effect.
