ABSTRACT:
A two-wire paper forming apparatus wherein the co-running forming wires converge over a forming roll and diverge over a couch roll downstream of the forming roll. A curved forming zone begins where the forming wires converge over the forming roll to receive a stock stream, and extends to before the couch roll whereby the forming roll in conjuction with a pair of convexly curved dewatering shoes disposed against the forming wires between the forming roll and the couch roll form the web while providing improved retention and formation.
