Abstract: There is disclosed a method and apparatus for processing material to produce recyclable waste. The material may be sorted, centrifugally milled and magnetically separated in a manner sufficient to produce multiple recyclable waste products.

Abstract: A panel is provided including multiple rows of parallel cells extending transversely of the rows and with the cells of adjacent rows of cells staggered longitudinally of the rows relative to each other, two, three, four and five cell row panels being disclosed. The panels are formed by folded material strips stacked one upon the other with each material strip having portions thereof glued together and adjacent material strips in each stack of strips glued together such that each material strip forms at least one complete cell of one row of cells and at least three-quarters of an adjacent cell in an adjacent row of cells.Also, a support system is provided for supporting the upper margin of a vertically disposed multi cell row panel wherein an upper cell or cells has one or two horizontal stiffening strips disposed therein and spaced beneath a stationery support strip.

Abstract: A strip conveyor and stacker receives cut elongated flexible strips from a strip former and by conveying and stacking the strips produces a stack of strips such as a cellular panel for a window covering. The conveyor receives the strips from the strip former and includes a foraminous conveyor belt which holds the strips on the surface thereof by suction. At the stacker, the strips are discharged from the conveyor belt by applying a burst of pressurized air, thereby ejecting the strips into a stacker magazine. As the strips are stacked, the magazine is indexed to increase its depth, or a cellular structure formed by the stacked strips is withdrawn from the body of the magazine. An auxiliary magazine may be used to form a preliminary stack of soft, flexible strips prior to stacking in the magazine. A strip defect sensor scans each strip and causes the ejection of defective strips from the apparatus.

Abstract: A treated fabric panel for use in fabricating expandable and retractable window coverings, partitions and the like, particularly honeycomb panels. The treated fabric panel is a textile material having at least one area thereof treated with a fabric treatment composition and at least one area thereof left untreated.

Abstract: A double panel window shade is formed by shade panels wound on inner and outer coaxial rollers. The inner roller includes a shaft secured at each end and journaled in mounting brackets at each end of the inner roller. The outer roller includes end plates journaled on the inner roller shafts. The outer roller defines a slot for receiving and passing the inner shade when said outer shade is fully unrolled from the outer roller. Each shade panel includes a bottom rail. A pull cord is provided for raising and lowering the shades by rotating the rollers. The pull cord is operatively connected to the inner roller by a dual direction spring clutch. The rollers are formed by a pair of roller tubes aligned one inside the other and each having a central axis, the axis of rotation of each tube being the central axis of the inner tube, and the central axis of the outer tube being spaced from its axis of rotation.

Abstract: Various systems for attaching flexible fabric material to rigid vanes in the construction of window coverings are disclosed. The various systems for attaching the fabric material to the vanes create varying aesthetic patterns while providing long-term durability. The systems described can be used to connect single or double sheets of fabric material to the faces of rigid vanes while enabling the vanes to be oriented vertically or horizontally.

Abstract: A ladder lacing unit (90) for a venetian blind assembly machine. The mechanism is formed by a movable carrier (102), with first and second ladder support guiding means (92) mounted on the carrier. A ladder support advancing means (98) is associated with each ladder support guiding means. Indexing means (90,104,204) are included for indexing the movable carrier (102) from a first position, in which the first ladder support guide means is accurately located to receive venetian blind slats, to a second position in which the second ladder support guide means is accurately so positioned.
