Abstract
A machine for creasing and slitting a travelling web, such as a cardboard web, characterized by an assembly which includes a carriage having a tool storage device with at least one spare tool and a lever arm mounting a tool for rotation. The lever arm is movable from a position with the tool engaging the web passing through the machine to a withdrawn position which enables changing the tool with one of the spare tools. Each of the assemblies is adjustably positioned in a transverse direction relative to the direction of movement of the web. The device includes a second group of assemblies which contains counter-tools for the tools of the first group.
