Device for spinning wire cores with paper tapes.

Patented in the German Empire on July 3, 1925,

Up to now it has been common practice in the manufacture of wire cord wrapped with paper tapes the paper tape rolls on several eccentric to the wire to be spun to store arranged carriers. There is also a machine for the production of twisted cords and ropes from yarn or wire known to reduce the centrifugal force on a plate with several coils are superimposed concentrically to the axis of rotation. Since with this device However, the material to be stranded is stranded in one point, this arrangement cannot be used for wrapping Use ladders with paper tapes, as these cannot be in one point run up, but their run-up points must be distributed over a greater length of the vein.

Claims (2)

The special design of the core spinning head forming the subject of the invention However, it allows .with several on a single plate concentric to the axis of rotation of the plate arranged to spin around discs and thus reduce the centrifugal force and to save space and thus costs. This is made possible by the fact that the individual from the tape rolls, unwinding tapes individually through the turns of one with the spinning plate rotating helical tape guide are guided. The drawing illustrates an embodiment of the invention, namely Fig. 1 shows a side view of the spinning head and Fig. 2 shows a plan view of this Fig. 3 shows a section in direction I-1 through the round bolts designated as smoother. The tapes running off the paper disks & are looped around the pegs c provided on the circumference of the plate / and arrive from there to the wire to be spun. helical turns of a tape guide e guided, which is connected to the plate /. So that the paper tapes brake each other, they are guided around the pins c in such a way that two disks lying one above the other run in opposite directions. By the windings of the tape guide the tapes run through the gap 'between two on the plate fixed to the bolt α to be wrapped wire. When the spinning head is rotated, the tapes are firmly attached to the core d and pull it against the bolt, which acts as a smoother. In this way, on the one hand, the wire is prevented by the straightener from dodging sideways under the tensile effect of the paper tapes, and on the other hand, it is achieved at the same time that the contact pressure between the wire and the straightener causes the wrapping of the wire to lie firmly and smoothly. Experience has shown that such an arrangement allows the production of tightly wound Increase cable cores considerably. ι. Device for wrapping wire cores with paper tapes, characterized in that several paper tape rolls (&) are provided on a plate centrally to the axis of rotation and the paper tape running off from each RoEe is guided through another 'turn of a helical tape guide (e) and through the smoothing device (a) connected to the spinning head is braked and smoothed. 2. Apparatus according to claim 1, characterized in that two superimposed Paper discs (ö) for the purpose of mutual braking in opposite directions Direction to be deducted. Fig. 3. \\ section ΙΊ Fig.i.
