Adjustable resilient blade support
View Patent ↗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.
1. An adjustable resilient blade mounting, for use in the forming section of a paper making machine, comprising in combination:
a base member having a leading face, a trailing face, a first edge and a second edge;
a first flexible member having a first edge and a second edge, the first edge of the first flexible member being attached to the first edge of the base member;
a first flexible hose member disposed between the second edges of the base member and the first flexible member;
a second flexible member having a first edge and a second edge, the second edge of the second flexible member being attached to the second edge of the first flexible member; and
a second flexible hose member disposed between the first edges of the first and second flexible members.
2. An adjustable resilient blade mounting according to claim 1 wherein the first edge of the base member is on the leading face of the base member.
3. An adjustable resilient blade mounting according to claim 1 wherein the first edge of the base member is on the trailing face of the base member.
4. An adjustable resilient blade mounting according to claim 1 wherein the mounting further includes a first cover disposed adjacent the second flexible hose member, and located between the first edges of the first and second flexible members.
5. An adjustable resilient blade mounting according to claim 4 wherein the first cover is attached to, or fabricated as part of, the second flexible member.
6. An adjustable resilient blade mounting according to claim 4 wherein a flexible seal is provided between a point adjacent to the second edge of the first flexible member and the base member.
7. An adjustable resilient blade mounting according to claim 4 wherein a flexible seal is provided between a free end of the first cover and the base member.
8. An adjustable resilient blade mounting according to claim 4 wherein a flexible seal is provided between a free end of the second cover and the base member.
9. An adjustable resilient blade mounting according to claim 1 wherein the mounting further includes a second cover disposed adjacent the first flexible hose member, and located between the second edges of the base member and the first flexible member.
10. An adjustable resilient blade mounting according to claim 9 wherein the second cover is attached to, or fabricated as part of, the base member.
11. An adjustable resilient blade mounting according to claim 9 wherein the second cover is attached to, or fabricated as part of, the first flexible member.
12. An adjustable resilient blade mounting according to claim 9 wherein a flexible seal is provided between a point adjacent to the first edge of the second flexible member and the base member.
13. An adjustable resilient blade mounting according to claim 1 wherein the mounting further includes a first cover disposed adjacent the second flexible hose member, and located between the first edges of the first and second flexible members and a second cover disposed adjacent the first flexible hose member, and located between the second edges of the base member and the first flexible member.
14. An adjustable resilient blade mounting according to claim 13 wherein the base member, the first and second flexible members, and the first and second covers are fabricated as a unitary construction.
15. An adjustable resilient blade mounting according to claim 1 wherein the base member and the first and second flexible members are fabricated as a unitary construction.
