Abstract

A method and apparatus for forming a non-tensioned multi- conduit line from a plurality of conduits and a central core as the plurality of conduits 10 and central core 12 are pulled longitudinally along the length thereof including the securing of conduits in a non-twisted contacting condition about the central core and oscillating the conduits about the central core prior to securing to alternately rotate the conduits in opposite directions about the central core such that the conduits contact the central core for substantially 360 DEG in each direction without introducing torsional stresses on the conduits prior to the securing thereof to the central core. <IMAGE>
