Abstract (en)
[origin: EP0227887A2] A unit (14) for loading a paper roll (10) onto a paper-roll support (1) of an intaglio printing machine is received in a pit (35) in front of the paper-roll support and is equipped with a pair of supporting rollers (16) which are intended for holding the new paper rolls to be loaded and which are mounted in a supporting structure (29) carried raisably and lowerably (23, 24) by a bogie (26) which, itself carried (33) movably, can slide by a drive of translational means (36, 37) on guides (34) which are anchored in the said pit where the unit is received. At the same time, there are sensors (42, 43, 44) which serve for centring the paper roll on the supporting rollers, for retaining the arms (6A, 6B) of the paper-roll support in the loading position and for mutual alignment between the core (11) of the paper roll and the clamping jaws (7) assigned to this core. The operation of changing the paper roll requires no expenditure of physical force and can be carried out by a single operator. <IMAGE>
