Abstract
A fabric for the sheet forming section of a papermaking machine is comprised of an upper and a lower layer of transverse threads interwoven with longitudinal threads. The number of transverse threads in the upper layer is twice as high as that in the lower layer. Within each weave repeat each longitudinal thread is interwoven two times with the upper layer of transverse threads. The transverse threads of the upper layer and the longitudinal threads form crimps disposed in the paper plane. First transverse threads in the upper layer form crimps reaching up to the paper plane which are supported in a crimp saddle of a longitudinal thread, and second transverse threads in the upper layer alternating with the first transverse thread form crimps reaching up to the paper plane which are supported by two adjacent longitudinal threads one of which ascends from the fabric interior to the paper plane while the other one descends from the paper plane into the fabric interior.
