  • Polygonal body, consisting of plastics soft foam, as filling material for cushions or the like
    Patent number: 4109332
    Abstract: A filling material for pillows, cushions and upholstery or the like is cut from a soft plastic foam material in the shape of a plurality of short four-sided rods, each having a body of polygonal shape. The bodies are each cut in such a manner that all side surfaces form surfaces of cut to reduce lumping and tearing of the bodies. Each body is formed with its height smaller than its breadth and its length in the range of one and a half times to five times the breadth, which breadth does not exceed a value of 10 mm. The bodies are each further cut to be rhomboidal in at least transverse cross section to provide surfaces joined at edges to form acute angles so as to enhance resilient properties thereof.
