Patent ID: 7086129

Claim:
In a method of making wound warps wherein a multiplicity of warp filaments are pulled off respective supplies and wound around a warp beam by rotating the warp beam while pressing the filaments against the beam with a predetermined packing force by a packing roller, the packing roller is deflected outward from the beam by the filaments as same are wound on the beam, an output is produced representing the rotation of the beam, an output is produced representing the rectified length of the filaments wound on the beam, and the outputs from a first wound warp are used as set points, the outputs from a subsequent wound warp are used as actual values and compared to the set points, and the force of the packing roller is varied such that the actual values of the subsequent wound warp are made generally equal to the set points the improvement wherein the output representing the rectified length is determined by generating an output corresponding to deflection of the packing roller.
