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.
A throughdrying fabric for use at the dry end of a paper making machine for carrying a moist web for conveyance through a throughdryer to form a basesheet, said fabric having a width corresponding to the width of the paper-making machine and a length in the form of a continuous loop corresponding to the length of the path of travel of the fabric through the throughdryer, and having a top pulp face and a bottom dryer face, said top pulp face producing a pattern on the confronting surface of the basesheet being formed from the moist web in the paper making machine by affording passage of the throughdrying air blown through said fabric and web comprising:
A method of making a throughdrying fabric comprising the steps of weaving the fabric on a loom with warps and shutes,
