Definitions

the present invention relates generally to a cable forming machine and in particular to a light-rotor static closer.
Such devices are suitable only for helping the cable to rotate about its axis along the path of the machine in order to avoid that it is braked during rotation and thus maintaining a relative motion between parts of the machine (substantially rotating members normally called fliers) and the cable itself. This is particularly important especially when using materials for cables which are unable to transmit sufficient elastic torques capable of overcoming the support reactions and frictions caused by them along the path of the cable itself.
An intrinsic drawback of the above-mentioned known device is that they require to rotate the cable through members substantially rotating at the same velocity of the cable and which at the same time transmit to the cable a suitable tensile stress state in the section of cable coming from the source i.e. the compacting point and allows the section of the cable downstream from such rotating member, to have the minimum tensile stress on the cable necessary to overcome the longitudinal frictions caused by support reactions distributed along the path of the cable.
This tensile stress in the terminal portion of the cable path is usually generated in the takeup area through suitable means generally but not necessarily located in the cable end collection area.
the present invention has for its object to overcome the above-mentioned drawbacks of the prior art closers.
the invention is based on the underlying idea of creating for the cable a rotating environment located preferably, but not necessarily, in the portion of the cable path in which the cable has to invert its advancing direction to be laid on the takeup bobbin and such as not only to help the cable in rotating about its axis but to force it to rotate by giving at its periphery the necessary revolving speed in a "natural” way and transmitting the rotation to the point of compacting the wires or elementary strands thus obtaining the desired cord.
numeral reference 1 indicates the guide channel whose longitudinal axis is is curved substantially in the form of a "question mark”.
the bending radius depends upon the diameter of the cable.
the channel is divided into elementary sections 3. Each section is realized in the form of a tube (fig.2) supported at its ends by means of bearings 4 e.g. ball bearings.
Adjacent channel sections are connected each other by means 5 capable of transmitting rotation between subsequent sections with such a convergence angle as necessary for obtaining the desired arcuate configuration of the channel.
the inner surface of the channel (fig.3) is preferably covered by an epoxy resin coating 6 (of the type used e.g. in drawplates, guides for chains, etc) and having each portion corresponding to each channel section shaped substantially like a revolution surface. It is constructed in such a way that the generating line in contact with the cable 9 corresponds necessarily to the configuration assumed by the cable.This is obtained by taking the portion of the plane line shaped like the natural path of the cable and comprised between the two ends of the channel section and considering this portion of line as the generating line with which the desired surface necessary for the cable can be constructed by revolution about the axis of the channel section.
the channel sections are mounted consecutively on the machine member (not shown) for supporting the cable by disposing them on a trellis (not shown) rigidly connected with a rotor 2 which rotates it.
the curved channel so formed is moved epicycloidally by the machine member itself if the end B, of the succession of channel sections, oriented toward the cable takeup area, is fixed, through lock means 7, to a point having a differential motion capable of making the tip speed of the channel section generating line in contact with the cable equal to the (rotation) tip speed of the cable (cable and channel section necessarily have different diameters).
differential lock means may consist simply in a clutch.
the channel described above is preferably, but not necessarily, inserted in a section of the cable path where the cable itself has to invert, with respect to an absolute observer, the direction of its longitudinal motion, i.e. in the area where the cable coming from the source inverts its advancing direction in order to be laid on the takeup bobbin 8 or given up to a pull group which does not rotate with the cable.
This static pull group can be e.g. a simple or double capstan, an axial caterpillar or a multiroll.
the above-described closer operates as follows.
the cable coming from the compacting point 10 is passed through the guide channel.
the cable settles along a geodetic line and therefore along a generating line of the channel itself and which represents a stable path for the cable.
the guide channel Upon rotation of the trellis through known and conventional means, the guide channel revolves with it about the axis along which the cable is disposed at the compacting point, called revolution central axis, and, having its end B constrained, the channel will rotate also about its axis as indicated in fig.1.
n is the revolution speed of the trellis
the speed at which the free end A of the channel revolves about its axis is 2n according to the double-twist principle, so that at the outlet end B the cable is stationary and therefore can be taken up.
the cable does not slide along the support on the generating line of the guide channel, but it is made rolling along the internal perimetric edge of the channel, while the torsion-vector is transmitted in a complete way.
the rotating channel according to the invention forces the cable to rotate about its own axis also in presence of strong support reactions.
this device it is possible to realize a static closer which does not need heavy stretch and torsion, rotating members mentioned at the outset, located between the source and take-up station.
the known system of three pulleys arranged at 120 degrees and connected each other to allow longitudinal skidding of the cable may be used.
the portion of the path represented with dashed line can be channelized in order to have the end A of the channel on the revolution central axis as indicated in fig.1, still maintaining the kinematic ratio between the two ends of the channel as required by the double twist principle.
