Title:
EXPANSION MEMBER FOR MATERIAL FEED-OUT ZONE IN PAPER MAKING MACHINE
Document Type and Number:
Japanese Patent JPH04327286
Kind Code:
A
Abstract:
PURPOSE: To restrict the pressure received in a cell to the range in expansion of the cell by setting at least one of a transverse wall and a wall connected with this wall to be highly expendable with respect to the other portions with individual parting wall portions.
CONSTITUTION: In the case of loading the pressure to one of the cells 30, 31, e.g. to the cell 31 through a pressure path 5, the parting walls 31.1, 32.2 are expanded and a ridge part 8.1 below the transverse wall 31.4 in the cell 31 is pushed downward. The expandability of a ridge part 8.2 is high and this movement is scarcely transmitted to the adjacent wide ridge parts 8.1 at both sides.
