Abstract
A throughdrying fabric for the drying section of a papermaking machine is disclosed in several embodiments. In each embodiment, the fabric has a load-bearing layer and a sculpture layer. The sculpture layer is characterized by impression MD knuckles, in the present instance formed as warp knuckles floating over a plurality of shutes but positioned substantially above the tops of the lowest shute knuckles in the load-bearing layer so as to provide machine direction knuckles projecting in the sculpture layer. Methods of weaving the fabric are disclosed using a standard fourdrinier loom. The loom may embody an auxiliary jacquard mechanism which is effective to control the impression warps in the sculpture level to produce a wide variety of patterns of impression knuckles which, in turn, produce an image on the pulp web which the throughdrying fabric carries through the machine.
