Anvil roll and external adjustment mechanisms therefor

An adjustment mechanism for an anvil roll comprising:

• a body having first and second axial ends and a hollow interior with a bore extending from the first axial end to the hollow interior, the body being configured to be mounted to an axial end of an anvil roll at the first axial end, the body hollow interior having a first adjustment drive and a second adjustment drive;
• wherein the first adjustment drive comprises a planetary gear train, the planetary gear train comprising an internal ring gear fixed to the body, a sun gear operatively connected to a first adjustment operator, and a planet gear rotatably connected to a planet carrier, the planet gear being disposed between the sun gear and the planet ring gear and intermeshing therewith whereby rotation of the first adjustment operator causes rotation of the sun gear and subsequent rotation of the planet gear around the sun gear and planetary internal ring gear and rotation of the planet carrier, the planet carrier having a extension portion, the planet carrier extension portion extending through the bore and being configured to operatively engage a first eccentric of the anvil roll;
• and
• wherein the second adjustment drive comprises a gear train with driven gear mounted to a shaft portion, a drive gear intermeshing with the driven gear to cause rotation thereof, and a second adjustment operator operatively connected to the drive gear to cause rotation thereof, the shaft portion extending through the bore and being coaxial with the planet carrier extension portion, the shaft portion being configured to operatively engage a second eccentric of the anvil roll.
