Disclosed are a bagged spring bed core with a side connected to a strip-shaped material and a manufacturing device and method thereof. The bed core is formed by arranging and bonding bagged spring strings connected to a strip-shaped material. The device includes a string feeding mechanism, a feeding mechanism, a tidying mechanism, and a sealing and cutting mechanism. The sealing and cutting mechanism cuts off the bagged spring string and the strip-shaped material to form bagged springs connected to the strip-shaped material. By bonding the strip-shaped material, the bagged spring string is no longer easily elongated or shortened by the action of an external force, so that the finally formed bagged spring bed core has good dimensional stability and can be compressed and coiled for packaging. Moreover, the strip-shaped material is provided between adjacent bagged spring strings in the bed core, so that the bed core has better durability.

The invention relates to a method for producing a textile composite material with shrink properties, in particular heat shrink properties, preferably in the form of a shrinkable, in particular heat-shrinkable textile upholstery and/or covering material, preferably for seating furniture, to the textile composite material obtained therefrom and to the uses thereof.

There is provided a skin-material fixing clip for connecting a skin material with a cushion material and provided with a locking section and a hook. The hook is provided with an extension portion extending downward from the locking section and a claw-shaped portion extending laterally from a distal end of the extension portion. The locking section is provided with a wire guide piece. A groove portion surrounded by the claw-shaped portion and the extension portion defines a wire holding space. Parts of the wire guide piece and the claw-shaped portion facing the wire insertion opening defines guide surfaces. The distal end portion of the wire guide piece and the distal end portion of the claw-shaped portion are provided to be spaced from each other along a direction parallel to an extending direction of the groove portion.

A seat cover (5) of a vehicle seat (1) includes: a welt seam part (17) in which seam allowances (15 and 16) of sewn skin materials (10 and 11) are split to right and left sides to be folded on the skin materials (10 and 11), and are sewn on the skin materials (10 and 11) by stitches (13 and 14) which are formed in the skin materials (10 and 11) along a seam (12) where the skin materials (10 and 11) are sewn; and a hook-and-loop fastener (18) provided in the welt seam part (17). The seam allowances (15 and 16) include edge portions (21 and 22) arranged outside the stitches (13 and 14). The hook-and-loop fastener (18) is fixed in the edge portions (21 and 22).

A method for manufacturing a vehicle seat cushion assembly includes providing a perforated outer material to define an outer seating surface. A backing material is sewn to the outer material using a first sewing line against which a wadding material is placed in a central region of the cushion. The wadding material is further secured by a hook and loop fastening product to the backing material. To secure the wadding material, a second sewing line is run. Left and right wadding materials are placed between the sewing lines and the edges of the cushion. Additional sewing lines laterally cross the longitudinal sewing lines to imbue the cushion with a wrist watch-like appearance.

An apparatus for upholstering a truss allows an operator to staple a fabric web to the truss, rotate the truss, further staple the semi-finished truss and cut the fabric web. The truss is fully upholstered after the end surfaces of the truss are wrapped up in fabric and the fabric stapled in place. The apparatus may accommodate different size trusses. A web of fabric is pulled around at least one roller in the apparatus by rotation of two vise mechanisms on opposite sides of the truss.
