  • Patent number: 6944900
    Abstract: A mattress having an inverted top panel/border seam, with an optional appended decorative rope welting on the border is described. An inverted seam secures the top panel to the border portion of a mattress cover to eliminate bumps and creases found in conventional welted top seam. Manufacturing costs may be reduced by eliminating the need for an expensive table-mounted tape edge closure machine and/or skilled operators, since the inverted seam may be flay sewn with a conventional sewing machine or even hand-stitched. Alternatively, a conventional tape edge machine can be used with less-skilled labor and or reduced tape/welting material, as all of the stitches and welting are hidden inside the mattress by the inverted seam.

  • Patent number: 6862763
    Abstract: A bedding or seating product comprising a spring assembly made up of a plurality of parallel strings of springs joined to each other. Each of the strings of springs comprises a row of interconnected pocketed coil springs. Selected pockets of fabric are shorter than adjacent pockets, so coil springs in the selected pockets are under a greater load than adjacent coil springs. In one preferred embodiment, every other pocket is under a greater load than the adjacent pockets, resulting in a checkerboard arrangement in at least one area of the product.

  • Patent number: 6694585
    Abstract: The apparatus has an indexable carriage adapted to move the coil springs and the border wire along a path. A wire cutter disposed adjacent the path has an inner member with an axial hole adapted to receive the wire and a tubular outer member receiving the inner member and movable relative to the inner member. The outer member has a cutting edge. An actuator is operatively connected to one of the inner and outer members to provide a relative rotation between the inner and outer members. That relative rotation results in the wire being sheared by the cutting edge to provide a length of wire. A wire wrapping mechanism disposed adjacent the path receives the length of wire and wraps the length of wire around an end turn of a coil spring and a border wire.

  • Patent number: 6175997
    Abstract: A method of assembling strings of pocketed coil springs into an innerspring core which may be used as the core of a mattress, cushion or similar body support foundation uses plastic netting reinforced nonwoven webs supplied between a pair of spaced apart heated rolls. Strings of pocketed coil springs are fed in seriatim into the nip between the rolls to heat the netting and activate an integral adhesive to bond the webs to the top and bottom surfaces of the pockets of each string. The core formed thus has reinforced webs on the top and bottom of the strings. The process overcomes the problems encountered when hot melt spraying is utilized to bond the pocketed coil strings together.

A backing member or first flexible member is operatively secured to the support surface and a second member disposed over the first flexible member. Other layers are then placed over the second flexible member and, in the case of quilt making, there would typically be just three layers. A basting gun having a hollow needle is then utilized by pushing the hollow needle through all of the layers of flexible material and into one of the openings in the spacing member. Then the basting tool is utilized to force the first end of the plastic fastener through the hollow needle so that this first end of the plastic fastener is on one end of the flexible members and the second end of the plastic fastener is on the other side of the flexible members whereby the flexible members are held together by the plastic fastener.

The upholstering or covering process comprises cutting out a flexible piece (25) to a shape corresponding to that of the object plus a border on its contour, providing the edge of this border with a tensioning thread sliding within a passage preserved by auxiliary threads, covering the object with the piece so that the border provided with the tensioning thread project beyond the object contour, folding back the border and applying tractions in opposite directions on the two ends (5a, 5b) of the tensioning thread to tighten and to fold this border, lastly, after the tractions have been applied, locking the ends of the tensioning thread either by tieing them together or by stapling them to the back of the object or by crushing a punched-out clip (31) on the back of the object.

  • Patent number: 4718153
    Abstract: A process for molding upholstered chair cushions comprising placing a sheet of upholstery fabric between two dies, one having sculptured effects thereon, the dies being movable toward each other to form a cavity between them. A cushion assembly having a thickness (with the upholstery) greater than the distances between the dies in the cavity is placed in the cavity after having been coated on at least one side adjacent the upholstery with an air permeable adhesive. The dies are urged together to compress the cushion in the cavity to force the fabric and the cushion to conform to the shape of the first die. Hot vapors are injected into the cavity to shape the cushion and the fabric generally to the sculpted configuration of the sculpted die.

  • Patent number: 4385427
    Abstract: The padded frame of a seat being upholstered rests on a support placing the back of the seat in vertical alignment under a carriage mounted on guides establishing a vertical freedom of movement of the carriage. The carriage has a cluster of resilient cantilever arms extending downward, each of the arms having a follower at the lower end adapted to move along the contour of the seat back. The cover for the seat back is slipped inside-out over the cluster of arms, and relative movement of the carriage toward the seat installs the cover outside-out. Other resilient arms in the cluster are preferably mounted on the frame of the machine, with relative movement provided by moving the seat unit with respect to the frame.
