  • Patent number: 4606792
    Abstract: An endless sieve band or composite band for paper machines and the like, has a plurality of helixes composed of an elastic wire and each having two opposite winding legs and also two head curves connecting the winding legs with one another and having a predetermined wire diameter and wire width, wherein the helixes are arranged so that when the head curve of one of two neighboring helixes is inserted into an intermediate space of another of the two neighboring helixes an overlapping region is formed into which an insertion wire is introduced, and the winding legs of each of the helixes include a supporting winding leg which has flat supporting sufaces with a width exceeding the wire diameter or the wire width of the head curves.

  • Patent number: 4599881
    Abstract: In a method and an arrangement for winding and forming helixes of elastic synthetic plastic and metal wire the wire is supplied from a wire supply device, windings are then wound from the wire so as to form straight winding legs connected by head curves, the windings are then separated to provide distances therebetween, the separated windings are widened in correspondence with the distances between them produced during the separation and the finished helixes are supplied to a helix supply device.
