A stranding unit for a stranding machine has a stranding axis and a cage in which a number of baskets are arranged for receiving a number of reels having a strand material wound thereon. The stranding unit is characterized in that a stand is arranged which has a frame which extends around the cage in a circumferential direction around the stranding axis. The cage is mounted on the frame by a number of frame bearing elements and is rotatable around the stranding axis. As a result of the circumferential bearing, centrifugal forces are particularly efficiently distributed and absorbed by the frame during operation. In an advantageous further development, a plurality of basket are also mounted in a similar manner within the frame. The stranding unit as a whole is furthermore constructed such that it can be operated at a particularly high rotational speed.

A cable winding machine for winding together a multiple number of subconductors into a composite cable includes holding means for holding a first subconductor in the machine direction, and in a predetermined orientation of the first subconductor about its longitudinal axis as it moves through the machine; a first rotating member arranged and rotate the second subconductor around the first subconductor as the second subconductor moves through the machine and one or more further rotating members arranged to hold further subconductors aligned in the machine direction and in a predetermined orientation about their longitudinal axes and rotate the further subconductors around the subconductors wound with one another in the first winding stage of the machine.

Apparatus (1) for stranding armor wires (11) about a cable core (10), the apparatus comprising a rotary plate (2) equipped with armor wire bobbins (3), a rotary distributer grid (4) driven by the plate, and a stranding die (5) for bringing together the armor wires around the cable core. The improvement lies in the apparatus including a coupling (20) situated between the plate and the distribution grid, together with a brake (40) for stopping the distribution grid. If a stranding operation is interrupted, the distribution grid is braked and stopped in time with the cable core stopping its longitudinal movement, leaving the plate to continue to rotate for a turn or more under its own inertia. Excess twist is thus prevented from crushing the cable core.

An apparatus for stranding wire, cables, ropes or the like, has one or more rotatable supports and a plurality of receptacles are non-rotatably mounted on each of the supports. A bundle of wound wire which is to be stranded is contained in each one of the receptacles which are positioned so that the axis of each bundle of wire is substantially parallel to the axis of rotation of the support. The wires from each of the bundles in a receptacle are then guided to a stranding point.

A method of, and apparatus for, manufacturing a stranded product from materials wound on feed reels journalled in a rotating feed cage. To permit operation at a maximum safe speed based on centrifugal force of the mass of material on the feed reels, an energy beam such as light is arranged to sense the diameter of the various feed reels. Cage rotation is then increased as permitted according to the observed diameter of charge of material on the reel having the greatest charge.

A high speed rigid-type strander includes a main shaft or body mounted for rotation about its longitudinal axis with the core wire advanced through the strander substantially along its axis of rotation. Bobbin supporting members are fixedly mounted externally on the shaft or body for rotation therewith and for mounting the bobbins in positions displaced from the axis of rotation. The bobbins are mounted with their longitudinal axes oriented at substantial angles from the axis of rotation of the shaft or body, and preferably at an angle substantially normal thereto. The bobbins can be mounted to either fly-off the wire in a generally radially outward direction or in a generally radially inward direction with the bobbins stationary about their longitudinal axes. A strander of the above general type is also described which can be used in either a fly-off mode of operation or in a traditional pay-off mode wherein the bobbins rotate about their own axes.

The device is used in a rope machine and comprises two drive pulleys of different diameters of which the smaller-diameter pulley serves for drawing out the twisted product immediately after its having been spun, while the larger-diameter pulley is for stretching the product. Spaced somewhat apart from the pulleys is a contrivance for passing the twisted product from one pulley to the other. The pulleys are interconnected through a friction clutch which is kinematically associated with a selfcontained drive controlled by the stretching force transducer adapted to interact with the member of the contrivance which is under maximum load imposed by the tightening force of the twisted product, the transducer producing a signal proportional to the force so as to enable the torque transmitted by the friction clutch from one pulley to the other, to be changed in the course of stretching process. Such an embodiment of the device enables automatic control of the stretching force applied to the twisted product under process.
