An improved printer-slotter is proposed which has a plurality of printing units (P1, P2) and a creaser/slotter unit (CS) separable from one another. Re-coupling the units after separation requires a troublesome work to set a phase relationship between the units. Prior to the start of the operation, initial phrase setting is performed by an initial phase setter (14) so that the rotating member (2, 5, 6) of each unit will be turned until its zero point comes to a predetermined initial phase. Thereafter, a common reference signal is supplied to the controllers (15) for all the units to maintain the phase relationship thus set. |
