John N Garner, Philip A McGettigan: Manufacture of telecommunications cable core units. Northern Telecom, R J Austin, December 24, 1985: US04559771 (1 worldwide citation)

Changing relative positions of conductor pairs along a telecommunications cable core by passing the pairs as they approach a core unit forming means, in an array through a flow of air which causes relative sideways movement of the pairs and continual change in their positions. The array may be arcua ...
