RADIALLY ADJUSTABLE ANVIL ROLL ASSEMBLY FOR A ROTARY DIE CUTTING PRESS

摘要

A radially adjustable anvil roll assembly (14) is provided for use with a die cutting cylinder (28) of a rotary die cutting press (12). The adjustable anvil roll assembly (14) comprises a shaft (56) mounted for selective and intermittent rotation on the press (12), and a pair of eccentrics (58) provided on an intermediate portion of the shaft (56). A hollow cylindrical sleeve (54) is mounted for free rotation on the shaft eccentrics (58). Rotating the shaft (56) so that the maximum eccentricity of the eccentrics (58) is directed toward the die cutting cylinder (28) adjustably positions the cylindrical sleeve (54) in its closest adjusted position toward the cylinder (28). Rotating the shaft (56) 180.degree. so that the maximum eccentricity of the eccentrics (58) is directed away from the die cutting cylinder (28) adjustably positions the cylindrical sleeve (54) in a radially adjusted position furthest away from the die cutting cylinder (28). The shaft (56) is selectively and incrementally rotated only when adjusting the relative position of the sleeve (54) to the die cutting cylinder (28) and does not rotate during cutting operations of the press (12).
