Abstract
The body of a mattress comprises a cocoon thread bundle of long fibers formed by reeling cocoon threads off cocoons and separating them one from another. The body the mattress also has inner layers sandwiching the bundle. The body is quilted at appropriate positions and covered by a suface cloth made of woven fabric, and the periphery of the body is fastened by a retention cloth. The mattress has touch different from, for example feather mattress and serves to reduce yarn breakage of the cocoon long-fibers which are used as the stuffing. The stuffing can be easily produced without fail by a process comprising the steps of reeling cocoon threads off boiled cocoons and winding them around a take-up reel, fusing the wound cocoon threads at appropriate positional, and cutting the fused bundles.
Claims13
A mattress, comprising:
- a thread bundle of long fibers, the bundle of long fibers being arranged in a repetitive pattern along a portion of the mattress;
- a pair of inner layers adjacent the thread bundle, the thread bundle being between the pair of inner layers;
- a quilting provided in the thread bundle, the quilting preventing movement of the thread bundle;
- a surface cloth made of woven fabric, the surface cloth covering the inner layers;
- and
- a retention cloth fastening said thread bundle, said inner layers, said quilting and said surface cloth,
- wherein the long fibers are a cocoon thread bundle reeled from cocoon threads from a plurality of cocoons.
A process for producing a mattress stuffing, comprising the steps of:
- reeling cocoon threads off a plurality of cocoon bundles and around a reel apparatus to form a wound thread bundle on the reel apparatus, the reel apparatus providing an interior space within the wound thread bundle;
- sewing the cocoon threads while wound around said reel apparatus, the cocoon threads in the wound thread bundle on a opposite side of the space separating the cocoon threads failing to be sewn together during the step of sewing;
- and
- cutting and processing a bundle of sewn cocoon threads on the reel.
An apparatus for producing a stuffing, comprising:
- a thread bundle container having a plurality of cocoon thread bundles;
- a reel apparatus reeling threads off said cocoon thread bundles to form a wound thread bundle;
- a transverse suspension shaft arranged between said cocoon thread bundle container and said reel apparatus, the transverse suspension shaft supporting separated threads;
- a sewing device having a long machine for sewing threads into the wound thread bundle, wherein said reel apparatus is integrated between a horizontal arm member unit having two horizontal arm members;
- a sewing table arranged between said reel apparatus and said sewing device;
- and
- an additional long machine, the additional long machine adjacent said reel apparatus for stitching the wound thread bundle,
- wherein a fastening frame is integrated between the two horizontal and members of the horizontal arm member unit and movable in a longitudinal direction relative to the horizontal arm member unit, the fastening frame holding the thread bundle.
