Statistical process control - procedures for charting warp
This Technical Information Paper will concern itself only with statistical techniques used to measure and chart cross directional warp. Because there are no accepted procedures to measure the magnitude of end-to-end, "S," and twist warp, other statistical techniques must be used to record and chart the presence of these additional types of warp.
