DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
The invention relates to a cable-twisting device or an apparatus for stranding elongated stranding elements, using a rotating accumulator extending in the longitudinal direction, via which the stranding elements are fed to a stranding disk.
An apparatus of this kind is known from EP 0 151 367 B1. There, provision is additionally made of freely rotatable perforated guiding disks on a tube accumulator, the said perforated guiding disks being driven independently with respect to the tube accumulator. The perforated guiding disk in this arrangement must be fitted as an additional element on the tube accumulator and must be supported. By means of the perforated guiding disk, the stranding elements are lifted off from the tube accumulator, since the guiding apertures of the perforated guiding disk lie on an increased part-circle diameter.
A tube, whose surface is intended to be designed to be extremely smooth is known from DE-A 24 11 151. For this purpose, the tube can be provided with longitudinally extending grooves, the stranding elements always running transversely over the grooves during stranding and bridging over the latter.
A stranding apparatus is known from EP A1 529 610, in which a tube, closed on all sides, is provided for each stranding element.
SUMMARY OF THE INVENTION
The invention is based on the object of configuring the construction of a stranding apparatus in a simpler fashion. According to the invention, this object is achieved in an apparatus of the type mentioned above, wherein the accumulator further has open chambers which extend in the longitudinal direction of the accumulator and serve for the accommodation of the stranding elements.
Hence, the accumulator itself effects the specific guidance of the stranding elements, as a result of which not only is an especially simple construction achievable but, in many cases, even a better mode of operation. By means of the use of open chambers, the accessibility and the insertion, respectively, of the stranding elements is especially simplified.
The invention relates also to a method for stranding elongated stranding elements, using a rotating accumulator, extending in the longitudinal direction, via which the stranding elements are fed to a stranding disk, which is characterized in that the stranding elements are guided in open chambers of the accumulator which extend in the longitudinal direction of the accumulator.
In an embodiment, an apparatus is provided for stranding elongated stranding elements. The apparatus includes a rotating stranding disk and a rotating accumulator extending in a longitudinal direction. The accumulator feeds the stranding elements to the stranding disk. Open chambers are disposed in the accumulator which extend in the longitudinal direction to accommodate and guide the stranding elements. In an embodiment, each chamber respectively extends in a normally straight longitudinal line.
In an embodiment, a fixing device is provided on which the accumulator is rotationally mounted.
In an embodiment, an inlet device is provided to guide the stranding elements from a source toward the accumulator.
In an embodiment, an insertion device is provided for inserting the stranding elements into the chambers.
In an embodiment, the cross-sectional shape of each chamber is larger than a cross-section of one of the stranding elements.
In an embodiment, the accumulator has radially extending separating elements which define the chambers. Accordingly, the accumulator may have a star-shaped cross section.
In an embodiment, at least one covering means at least partially encloses the accumulator closely against the chambers. This covering means may include an outer tube which surrounds the accumulator concentrically. The outer tube may have a circular cylindrical shape. In an embodiment, the outer tube extends substantially over an entire portion of the accumulator on which the strands are accumulated. In another embodiment, a plurality of outer tubes may be provided which are arranged in a spaced longitudinal
