POLSTERMATERIAL FUER MATRATZEN |
摘要 |
<p>A cushioning material for mattresses is formed by needling a pile of crimped fibers to form a flat board, and then continuously and alternately bending the flat board to form a corrugated web. The corrugated web thus formed has a number of side-by-side contact portions and a number of bent portions connecting the side-by-side contact portions. The bent portions thus form a relatively soft surface portion of the cushioning material, and the side-by-side contact portions provide a moderately rigid portion of the cushioning material. The corrugated web may be held together by sewing, bonding or welding.</p> |
