Anvil Roll and Internal Adjustment Mechanisms Therefor

摘要

An adjustment mechanism for an anvil roll has a body with first and second ends and a hollow interior. A bore extends from the first end into the hollow interior. The body is mountable to an axial end of the anvil roll at the first end. The hollow interior has first and second adjustment drives. The first adjustment drive extends from the second end of the body into the hollow interior and comprises a gear train with drive gears extending between a first adjustment operator and a first shaft extending from the body hollow interior through the bore of the body to the first end of the body. The second adjustment drive comprises a gear train with drive gears extending between a second adjustment operator and a second shaft extending from the hollow interior through the bore of the body to the first end of the body.

主权项

1. An anvil roll comprising:
a sleeve having first and second axial ends and a hollow interior; a shaft having a center axis extending between first and second axial ends of the shaft, the shaft being disposed within the hollow interior of the sleeve with the sleeve first axial end adjacent to the shaft first axial end and the sleeve second axial end adjacent to the shaft second axial end; a first bearer adjacent to the shaft first axial end and a second bearer adjacent to the shaft second axial end; a first cylindrical mounting surface adjacent to first and second axial ends of the shaft, the first cylindrical mounting surface having a center axis radially offset from the shaft center axis, the shaft being operatively connected with the first and second ends of the sleeve at the first cylindrical mounting surface to allow relative rotary motion between the sleeve and the shaft; and a second cylindrical mounting surface adjacent to the first axial end of the shaft, the second cylindrical mounting surface having a center axis radially offset from the first cylindrical mounting surface and the shaft center axis, the shaft being operatively connected with the first bearer at the second cylindrical mounting surface to allow relative rotary motion between the first bearer and the shaft; and a third cylindrical mounting surface adjacent to the second axial end of the shaft, the third cylindrical mounting surface having a center axis co-axial with the shaft center axis, the shaft being operatively connected with the second bearer at the third cylindrical mounting surface to allow relative rotary motion between the second bearer and the shaft.
