ABSTRACT:
A machine for continuously scoring and slitting paper, such as corrugated board and the like and for changing the pattern of cuts and scores while the paper is in motion. Two sets of scoring and slitting rollers having a plurality of scoring and slitting assemblies thereon are used, only one of which is in use at any time. The inactive set of rollers can be adjusted and secured in a new cutting pattern while the other set is operating. The scoring and slitting assemblies on the rollers are moved into position by a common threaded rod. Each roller, scoring or slitting assembly, is provided with a split nut and an electrically controlled clutch which is used to engage the nuts and to move the roller assemblies selectively along the threaded rod to a desired cutting position.
