  • Publication number: 20060163038
    Abstract: Conveying wire (2) with disc-shaped conveying members (8) for use in endless tube conveyor systems, the wire (3) consisting of a number of twisted strands (4) that each are made of thin threads or fibers, and including an outer jacket (6) to which the said conveying members (8) are fastened directly by injection moulding, where the said outer jacket (6) consists of a polymer with a melting temperature which is lower than the melting temperature of the plastic material from which the conveying members are injection moulded, and where the wire (3) e.g. is made as a balanced (torsionally neutral) wire consisting of at least three strands that each are made of very thin synthetic fibres which are individually surface treated with a polymer, providing great bending wearability to the fibers and good adhesion to the outer jacket (6) which consists of a polymer.

  • Patent number: 4871060
    Abstract: A scraper conveyor comprising a conveyor chain or wire provided with a plurality of transverse scraper discs and passing along a closed path at least partly defined by a stationary conveyor channel or a tube extending from a material inlet station and past at least one receiver station, in which the material is dispensable through outlet openings in said channel or tube. The conveyor chain or wire is driven by a driving wheel engaging the transverse scraper discs, with the driving wheel being a circumferentially substantially smooth wheel having an outer cross sectional shape which conditions a frictional engagement between the wheel and the wheel periphery engaging portions of the outer edges of the scraper members. A tightener is provided for tightening the moved element of the conveyor about the driving wheel sufficiently to ensure a firm frictional engagement between these parts.
