Abstract
The suction strip is mounted via a tube carrier on a pair of supports so as to pivot about an axis extending longitudinally of the carrier. The pivot axis is located in a vertical plane which passes through the front tip of the suction strip. Pivoting is effected via a leaf spring which mounts the carrier on the supports and at least one adjusting screw. The adjusting screw may have different thread pitches at opposite ends to obtain a coarse and fine control.

A suction device for a paper machine comprising
- a suction strip having a suction surface for cooperating with a wire of the paper machine and a front tip;
- a carrier having said suction strip rigidly fixed thereon, said carrier being disposed transversely of the wire of the paper machine;
- a pair of supports pivotally supporting said carrier about a common pivot axis extending longitudinally of said carrier and located in a plane extending through said front tip of said suction strip perpendicularly of the wire, each support being disposed at a respective end of said carrier and including a housing for mounting on the paper machine, a leaf spring rigidly fixed to said housing and vertically disposed in said plane, and a plate mounted on said carrier and secured to said leaf spring;
- and
- an adjustment means on at least one end of said carrier for pivoting said carrier about said common axis relative to said supports.
