Abstract
Abstract The cable is made by cascaded SZ pattern stranding of elements (individual conductors, or bundles) in a first stranding level by means of multiple units each having a stationary aperture disk, a reversably revolving aperture disk, a tube between them, and a stranding head downstream from the revolving disk, with a wrapping station between them, resulting in plural, stranded bundles serving as stranding elements in a further unit for second-level stranding and being basically similarly constructed as each of the first-mentioned units.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
168 words
A stranding machine, comprising: a plurality of stranding units, each including (i) a stationary disk with apertures; (ii) a rotatable disk with apertures; (iii) a tube extending between the disks and being fastened to one of them; (iv) a stranding head downstream from the rotatable disk; (v) a wrapping unit disposed between the rotatable disk and the head; means for feeding stranding elements to said units so that a plurality of stranded bundles leave said heads; a single drive means connected to all of said rotatable disks for reversibly driving all of the rotable disks; a further stranding unit having a stationary disk with apertures, a rotatable disk with apertures, a tube extending between the latter disks and being fastened to one of them, a stranding head, and means connected for reversibly driving said latter rotatable disk; and said stranded bundles being fed to said stationary disk of said further stranding unit so that a higher-order stranded bundle may be withdrawn from the head of further stranding unit.
Claim 2
Dependent Claim
168 words
A stranding machine, comprising: a plurality of stranding units, each including (i) a stationary disk with apertures; (ii) a rotatable disk with apertures; (iii) a tube extending between the disks and being fastened to one of them; (iv) a stranding head downstream from the rotatable disk; (v) a wrapping unit disposed between the rotatable disk and the head; means for feeding stranding elements to said units so that a plurality of stranded bundles leave said heads; a single drive means connected to all of said rotatable disks for reversibly driving all of the rotable disks; a further stranding unit having a stationary disk with apertures, a rotatable disk with apertures, a tube extending between the latter disks and being fastened to one of them, a stranding head, and means connected for reversibly driving said latter rotatable disk; and said stranded bundles being fed to said stationary disk of said further stranding unit so that a higher-order stranded bundle may be withdrawn from the head of further stranding unit.
Claim 3
Dependent Claim
19 words
In a stranding machine as in claim 1, wherein said drive means imparts different speeds upon said rotatable disks.
Claim 4
Dependent Claim
39 words
In a stranding machine as in claim 1 or 2, wherein said single drive means imparts upon some of said rotatable disks rotation in one direction and rotation in the opposite direction upon the remainder of said rotatable disks.
