Title:
METHOD FOR TWISTING WITH FINE WIRE
Document Type and Number:
Japanese Patent JP2001271283
Kind Code:
A
Abstract:

To efficiently twist relatively fine wire having relatively high elasticity in good appearance.

This method for twisting fine wire comprises giving twisting- back to each of a plurality of and relatively fine raw wires having high elasticity and then twisting them together. The twisting method is characterized by setting the ratio N1:N2:N3 to -(0.4 to 0.7): 1: (0.8 to 0.95) wherein positive or negative sign represents a rotation direction, when twist frequency c>f twisting- back of raw wire 11, 12 or the like is defined as N1 and twist frequency of intertwisting is defined as N2 and twist frequency of winding is defined as N3 and adequately selecting values within the above range according to material of each raw wire, outside diameter, the surface state, linear velocity and the extent of rotation number of twisting.
