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 selec- tive and intermittent rotation on the press (12), and a pair of eccentrics (58) provided on an intermediate por- tion 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 ec- centricity of the eccentrics (58) is directed toward the die cutting cylinder (28) adjustably positions the cylin- drical sleeve (54) in its closest adjusted position to- ward the cylinder (28). Rotating the shaft (56) 180° so that the maximum eccentricity of the eccentrics (58) is directed away from the die cutting cylinder (28) ad- justably positions the cylindrical sleeve (54) in a radi- ally adjusted position furthest away from the die cutting cylinder (28). The shaft (56) is selectively and in- crementally 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).
