US 2004/0069431 A1 · Adjustable resilient blade support

Abstract

An adjustable resilient blade support for use in the forming section of a papermaking machine. The blade support is adjustable, both to allow the attached blade to be moved from a position where it is out of contact to a position where it is pressed into contact with the adjacent forming fabric, and to permit adjustment of the blade orientation relative to the surface of the forming fabric. The blade support is also resilient, and thus allows the blade to respond to transient localized changes in the path of the forming fabric with which it is in contact. The adjustable resilient blade support of this invention is thus of use in an open surface forming section, and also is of use in forming sections in which two forming fabrics are used.
