Wound warps are made by pulling a multiplicity of warp filaments off respective supplies and winding them 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, and an output is produced representing the rotation of the beam. Another output is derived from this outward deflection of the packing roller that represents the rectified length of the filaments wound on the beam. The outputs from a first wound warp are used as set points, and the outputs from a subsequent wound warp are used as actual values and compared to the set points. 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.
