A cover-material fixing clip includes: a chuck having a base portion, a first holding piece and a second holding piece; a hook configured to be engaged with a wire to be located in a groove of a cushion material; and an engagement opening defined between the chuck and a leading end of the hook. The base portion, the first holding piece and the second holding piece define a retention groove for holding the held body attached to the cover material. The engagement opening has an opening dimension in a range from 50% to 80% of a width of the retention groove.

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.

There is provided a cover-material fastening end member including a band-shaped member and a locking member. The locking member is formed such that a width thereof in a direction perpendicular to a surface of the band-shaped member is wider than a width of the band-shaped member. The locking member includes: a center plate-shaped portion, a flange portion, and a plurality of rib portions. The flange portion has a surface extending along a longitudinal direction of the end edge portion of the band-shaped member and perpendicular to a surface of the center plate-shaped portion. The rib portions each has a surface intersecting with the center plate-shaped portion and the flange portion. The rib portions are provided on the center plate-shaped portion along the longitudinal direction of the center plate-shaped portion at predetermined intervals.

There is provided a cover-material fixing tool. A cover-material fixing end member is configured to be attached on a cover-material. A clip is configured to be attached on a cover-material fixing end member. The cover-material fixing end member includes a tape member, a clip locking member, and a plurality of stoppers. The clip includes a locking portion for holding the clip locking member to allow the clip locking member to move in a longitudinal direction, and a locking protrusion protruding toward the clip locking member and configured to abut against the stoppers. The clip is movable between the adjacent stoppers to allow position adjustment thereof.

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.
