To provide a method and apparatus for forming paper web from paper stock which is free from causing harmful effects such as undesirable distribution of fine and filler, etc., even in increasing traveling speed of a paper making machine.
There are provided the method and apparatus for beginning the formation of the paper web on a looped forming wire traveling in a continuous path, or between a pair of converging forming wires. The apparatus includes a headbox for jetting a stock stream onto the forming wire, or between the forming wires over the whole of the porous face surface of a forming shoe. A plurality of openings, for example, drilled holes, small slots, and honeycomb perforations are made on the porous face surface of the forming shoe to eliminate the water squeezed out by adjacent forming wire from the paper making machine by making the water travel by a controlled method using the forming shoe.
