RADIALLY ADJUSTABLE ANVIL ROLL ASSEMBLY FOR A ROTARY DIE CUTTING PRESS

摘要

A radially adjustable anvil roll assembly is provided for use with a die cutting cylinder of a rotary die cutting press. The adjustable anvil roll assembly comprises a shaft mounted for selective and intermittent rotation on the press, and a pair of eccentrics provided on an intermediate portion of the shaft. A hollow cylindrical sleeve is mounted for free rotation on the shaft eccentrics. Rotating the shaft so that the maximum eccentricity of the eccentrics is directed toward the die cutting cylinder adjustably positions the cylindrical sleeve in its closest adjusted position toward the cylinder. Rotating the shaft 180 DEG so that the maximum eccentricity of the eccentrics is directed away from the die cutting cylinder adjustably positions the cylindrical sleeve in a radially adjusted position furthest away from the die cutting cylinder. The shaft is selectively and incrementally rotated only when adjusting the relative position of the sleeve to the die cutting cylinder and does not rotate during cutting operations of the press.
