ABSTRACT A method and apparatus for continuously measuring the compressive strain and determining the compressive pressure on rolls of flexible material as they are being wound and for measuring the accu- mulated length of material wound on the roll. An accurate measurement is recorded of the length and caliper of each layer of the roll. From these meas- urements, the compressive strain and compressive pressure are determined and this information is used to control the winding process. The length measure- ments are also employed to correct the accumulated length measurement after the winding has been inter- rupted for removal of defective layers of material.
