ABSTRACT:
A paper slitter machine having a plurality of slitter heads in mutually spaced apart relation located across the width of the machine, each slitter head having a slitter disc operable in cooperating relation with a respective annular disc or slitter band mounted for rotation on a shaft, for the slitting of a paper web into discrete width portions on passage of the web past the slitter heads, is provided with a plurality of slitter indexing means mounted on traverse means for retraction to a position clear of the machine, the slitter indexing means having a slitter stop for each slitter head, the stops being adjustable upon the traverse means to permit pre-indexing of each of the stops to a desired predetermined position along the length of the traverse means such that, with the traverse means repositioned within the slitter machine and having the stops positioned in an operative position, each of the slitter heads may then be brought rapidly into indexed relation with the respective pre-set stop, whereby the slitter machine may be re-indexed with a minimum of down time. The indexing of the slitter machine is generally achieved in this arrangement by moving each of the annular slitter band discs into abutting relation with the respective pre-set stop, and thereafter bringing the respective disc into operative relation with the respective indexed slitter band disc.
