Abstract

A reference strand (tref) is parallel to a strand (tk) which is being hauled into place by a jack (1). The tensions/extensions in the reference strand and the successive strands being positioned are measured by gauges (3,2), stored in memories (16,13) and processed by a calculator (15). A comparator (14,17) controlling the jack pump (18) ensures that a particular strand (tk) is strained to an extension equal to a function of previous reference and strand values
