A machine (1) for making blanks (2) for boxes to measure, comprises feed means configured for realizing rectangular pieces (3) of the blank (2). Each rectangular piece (3) has a width (La), measured along a first edge (3a) thereof, which width (La) is equal to a pre-determined width (La) of the blank (2) and a length (Lu), measured along a second edge (3b) of said rectangular piece, said length (Lu) being preferably less than a pre-determined length (Lu) of the blank (2). Joining means (32) are configured for joining at least two rectangular pieces (3) or one rectangular piece (3) and a piece of an intermediate blank previously made, relative to respective first edges (3a), so as to obtain a blank exhibiting an intermediate width (La), which intermediate width (La) is equal to the pre-determined width (La) of the blank (2), and a length which is greater than the pre-determined length (Lu) of the blank (2). Cutting means (40) are configured for cutting the intermediate blank parallel to the first edges in order to obtain the blank (2).

An arrangement for a corrugator for producing corrugated cardboard comprises a material web delivery device for delivering a material web and an edge cutting device, which is arranged downstream of the material web delivery device in a transport direction of the material web and has at least one edge cutting apparatus for edge-cutting the material web, and a digital printing device, which is arranged downstream of the edge cutting device in the transport direction of the material web for printing on the material web.
