A module for a web-processing machine includes a sub-frame to which are mounted an operating roll (such as a die roll), and means urging the operating roll in one direction. The sub-frame can assume a position in which the operating roll is juxtaposed against and parallel with a driven anvil roll, and a further position in which the sub-frame is released, allowing the operating roll to move away from the anvil roll, so that the operating roll can be quickly and easily removed for replacement or maintenance. Preferably, the sub-frame is hingedly connected to the machine for rotation between the above positions.
