Abstract:
For SZ stranding, the stranding elements which remain united in the stranding or twisted unit are led in a stretched twisted condition to a twisting device which twists the twisted unit in sections, each of a multiple of stranding strokes. The twisting device is positioned closer to the takeup point than to the payout point of the twisted unit. A longitudinal section of the twisted unit has a minimum length equal to the distance between the takeup point and the twisting device and a maximum length equal to three times the distance between the twisting device and the payout point.
Abstract:
An improved communications cable and a method of making the same so as to minimize cross talk between units within the cable, in which a plurality of SZ stranded units are twisted to form groups which are then formed into layers so that adjoining units in any one layer have a different distribution function of length of lay and/or distance of reversal points of twist directions and with adjacent units in one layer similarly have different distribution function of length of lay and/or distance between reversal points than units in adjacent layers.
