SPOOL FOR WINDING FINE WIRE AT HIGH TENSION WITH FLEXIBLE CORE

摘要

A spool (200) for winding fine wire at high tension on is disclosed that is particularly suitable to wind steel wire used for sawing of hard and brittle materials. The spool has different inventive aspects. There is the aspect of a core (202) of such spool that shows a radial modulus that is lower than in any other known design of a sawing wire spool. A coil of sawing wire wound on this inventive spool shows a reduced wire interlayer pressure throughout the wire pack. In this way the inventive spool solves the problem of self-damage of the wire during sawing. Over and above the spool is re-usable.
