Abstract: A method of production of a conveying wire that includes a fiber wire with disc-shaped conveying members, the fiber wire including twisted strands each made from synthetic plastic threads or fibers, includes coating at least one section of the fiber wire with an outer jacket by a continuous injection molding process and connecting disc-shaped conveying members by injection molding directly onto the at least one section of the outer jacket or directly onto the fiber wire, and connecting opposed end parts of each section of the outer jacket to opposed end parts of disc-shaped conveying members, while maintaining the fiber wire under tension during unwinding and during winding.

Abstract: The invention is a conveying wire (2) with disc-shaped conveying members (8) for use in endless tube conveyor systems. The wire (3) consists 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 conveying members (8) are fastened directly by injection molding, where the 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 molded. The wire (3) is, for example, made as a balanced (torsionally neutral) wire consisting of at least three strands that each are made of very thin synthetic fibers 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.
