A filled article 10 such as a pillow, duvet, or cushion with two fabric layers 12a, (12b, figure 2) enclosing a filling (14, figure 2). The edges of the fabric are joined by discontinuous ultrasonically-formed seams 16a-d. There may also be a continuous ultrasonically-formed seam 15, which may be positioned outward of the discontinuous seam. There may be many discontinuous ultrasonically-formed seams alongside one or more edges. The discontinuous seam may be a stitch pattern such as running, zigzag or tent stitch. The fabric layers may be heat-sealable. The fabric may be a polymer and the filling microfibre. The invention also relates to a method for forming a filled article 10 of two fabric layers 12a, (12b, figure 2) enclosing a filling (14, figure 2) with the steps of; welding one or more edges with a discontinuous ultrasonically-formed seam 16a-d, inserting the filling between the fabric layers and then closing the article with a further discontinuous ultrasonically-formed seam or seams 16a-d. |
