  • the papermaking raw material discharged from the head box onto the wire is immediately sandwiched between the wire and the felt by lowering the forming roll, and the thin paper is opened. Since the paper can be made with a shorter section, scattering of papermaking raw materials on the wire is prevented, and thin paper can be made at a high speed.
  • the papermaking raw material discharged from the head pox onto the wire is immediately sandwiched between the forming roll and the wire, and a shear flow is generated in the papermaking raw material. Since the fibers are oriented in the running direction of the wire, soft thin paper can be easily made. Thus, according to the apparatus of the present invention, not only thick paper but also thin paper can be formed at high speed.

Since the so-called backflow may occur and the paper may be seriously damaged if the swallowing is impossible, the forming roll 13 is moved to the raised position indicated by the broken line in FIG. At this time, the head box 1 and the forming board 4 are set to the horizontal positions indicated by broken lines so that they are in the same direction as the traveling direction of the wire 2 near the head box 1. Therefore, at the time of cardboard making, it is operated as an apparatus for forming wet paper in the same manner as the conventional paper forming apparatus shown in FIG.

Abstract

L'invention concerne un dispositif de formage de papier d'une machine à fabriquer le papier que l'on peut commuter en une structure appropriée pour le formage à grande vitesse de papier fin et le formage de papier épais. Le matériau (S) pour la fabrication du papier est déchargé d'une caisse de tête (1) sur un câble (2), déshydraté par des déshydrateurs (5) pendant son transfert par le câble (2), et déshydraté encore par une caisse aspirante (6), un cylindre à former (13), qui permet à un feutre (7) s'étendant de la caisse aspirante (6) d'y être appliqué, est disposé de manière à pouvoir être soulevé sur le câble (2) à proximité de la caisse de tête (1) et, au niveau du formage du papier, le cylindre à former (13) est abaissé de manière à former un espacement entre le câble (2) et le feutre (7) de sorte que la matériau (S) à fabriquer le papier, déchargé de la caisse de tête (1), peut être relativement immédiatement retenu par le feutre (7) et le câble (2).
