Abstract: For a method for manufacturing a hollow shaft with at least one integral flange made of fiber composite, a plurality of intersecting windings of fiber material are applied onto a core. Moreover, the core has, for each flange, a radial spreader ring with an axial bearing surface. The windings are laid over an outer circumferential portion of the respective spreader ring and fixed.

Abstract: Process for winding and unwinding a parallel wire strand consisting of a multiplicity of individual wires onto and from a cable drum, and apparatus for performing such process. In the winding process, the parallel wire strand which is supplied in generally circular cross-sectional shape is fanned out so as to form a layer or layers of individual wires disposed in generally parallel position. The lead ends of the wires are anchored and such anchored end is mounted in a support therefor in the interior of the drum in such a manner that the subsequent winding of the individual wires in layers on the drum is without tension. In the unwinding operation, the individual wires are reformed into such circular cross-sectional strand shape at the bridge construction site, with corrosion-preventing material being applied to the individual wires during such unwinding, and a tubular casing of metal or plastic subsequently formed around the wires for sealing the same.

Abstract: A machine for gathering and packing a long length of filter sleeve, e.g. 500 feet, onto a short cartridge tube, e.g. 5 feet, for subsequent dispensing therefrom onto a continuous length of soil drainage tubing as such tubing is laid in the ground. The cartridge tube with a collar at its rear end is supported on an elongated support bar, against a backing collar held by a frictional brake. A continuous length of filter sleeve is fed over the cartridge tube and is gathered by a pair of rubber-tired gathering wheels, which are mounted so as to progress along the tube against an opposing bias as the gathering progresses. When a suitable length of sleeve has been gathered by the wheels onto a partial length of the tube, a packer collar is forced against the gathered sleeve, the wheels being retracted, so as to pack the sleeve on the cartridge tube and against the cartridge collar or the previously packed sleeve.
