ABSTRACT:
Disclosed is an improved wire-length measuring apparatus including a rising-and-descending roller unit, which is designed to be lowered to pull down all or selected wires stretched under tension and each fed out of an associated wire supply reel to measure the wires in terms of a different level at which the wires are pulled down. The roller unit has upper and lower rollers. When the roller unit rises to an upper level for measuring a subsequent shorter wire length, some selected wires are withdrawn so that their valley points come up to the upper level. Pinch rollers are designed to invade somewhat the area between the upper and lower rollers of the roller unit just before the wire measurement starts, thereby keeping the withdrawn wires pushed against the upper and lower rollers just before the wire measurement is completed. As a result, curling of the withdrawn wires can be prevented.
