ABSTRACT:
A papermakers' felt for the press or dewatering section of a papermaking machine is formed with an inner woven fabric and with a plurality of longitudinally extending, transversely spaced heavy yarns or strands which are supported on the bottom surface of the fabric by a relatively light cross-machine yarn or binder pick which interconnects the heavy strands with the warp yarns of the fabric. A batting of non-woven material is needled primarily into the upper surface of the inner fabric to form the top of the felt. The underlying strands define therebetween relatively open, longitudinally extending spaces or channels into which the water from the web of paper can flow. Some fibers of the batting intermingle and interlock with the strands to provide additional stability to the felt.
