Apparatus for forming multilayered paper includes an endless loop of felt and at least two short wire units provided beneath the loop of felt. Each short wire unit has a fixed dehydrator having a forming shoe, at least part of the upper surface of which is curved, and a short wire traveling over the curved part of the upper surface of the forming shoe. The endless loop of felt is engaged with the short wire on the curved upper surfaces of the forming shoes of the fixed dehydrators. Stock is ejected from a head box onto each short wire unit and is moved between the endless loop of felt and the short wire of the unit where the stock is dehydrated to thereby form a paper layer. Each of a forming roll and a couch roll guiding the felt into engagement with the short wire, and a felt roll disposed beneath the felt downstream of the short wire unit, can be moved vertically. By raising the felt with the felt roll and moving the forming and couch rolls vertically, the short wire and the endless loop of felt can be disengaged. Therefore, the short wires can be easily replaced.
