Abstract:
Braiding or stranding machine (1) for braiding or stranding a cord-shaped material, for example wires, having a rotor which is mounted on a single or multiple part rotor shaft (5, 6, 22), which is driven by at least one motor (8, 8a, 8b). The braiding or stranding machine (1) is arranged at least partially in a space (2) which is enclosed by an envelope (3) and is filled with a medium with a density less than the density of the ambient air, for example by producing negative pressure or by using helium. Because of the lesser air resistance on the rotor, this leads to a lower energy consumption, less noise development and a lower excitement of vibrations. The rotor shaft (5, 6, 22) can be arranged fully inside the envelope (3) of the enclosed space (2) or the rotor shaft (5, 6) has at least one section of a smaller diameter, only a section of a smaller diameter penetrating the envelope (3). This means that air seals (14) with parts in contact with each other and rotating contrary to each other are avoided or high wear of such seals (14) is reduced.

Abstract:
The present invention relates generally to industrial machinery, specifically to apparatus (1) for the manufacture of twisted wire (12) from two or more feed wires (10), whereby the twisted wire (12) is taken up onto a take up spool (3). The take up spool (3) is axially reciprocatingly displaceable along its longitudinal axis (15). The feed wires (10) are advanced through the apparatus by a capstan (19) configured and disposed to be axially aligned with the twisting means (2, 8) of the apparatus (1).

The steel cord has improved abrasion resistance and can contribute to the reduction of the weight of the tire.
Abstract:
An improved system for handling delicate linear media and in particular to a method and apparatus for winding delicate linear media such as superconducting wire or optical fibers onto a spool. A combination of direct closed loop control and media routing design facilitates the handling of the delicate media without causing damage. The axial tension in the linear media may be closely controlled during winding by means of feedback control loop using tension measurements to control the rotation speeds of the wind-from and wind- to spools. Further, during winding, the delicate linear media is only exposed to large radius bends with no reverse bending. Finally, output devices and features, commercial or otherwise, made possible by delicate linear media handling are revealed. This includes advanced SC devices and features.
Abstract:
Flyer bow (1) for a wire-braiding or cable-twisting machine, comprising a bow member (2) that has a groove (3) extending essentially along the entire longitudinal extension of the flyer bow (1) in the longitudinal direction of the flyer bow (1). The flyer bow (1) comprises a tubular guiding element (4), especially a coil spring, for guiding the elongate strand-type material that is placed in the groove (3) without interruption, essentially along the entire longitudinal extension of the groove (3). The inner dimensions of the groove (3) at any point along the longitudinal extension of the guiding element (4) are greater than or equal to the outer dimensions of the guiding element (4) at the same point. This makes it easy to remove and introduce, preferably pull out and insert, the guiding element (4) from and into the groove (3).
