Abstract
A papermakers forming fabric having two layers of CMD yarns interwoven with a system of MD yarns to form a multilayer fabric. The paper support surface CMD yarn layer has at least three times as many CMD yarns as the machine contact surface CMD yarn layer. The higher count of upper layer CMD yarns provides an improved paper forming/carrying surface with improved drainage characteristics.
