Abstract

A multiple shaft, turret roll-slitting machine having a slitting knife mounted for movement along a path parallel to the axis of a roll to be slit and for radial movement into the roll at selected axial locations. The machine has at least two shafts upon which rolls of material are to be mounted and those shafts are movable from a cutting station to a loading and unloading station and are mounted on a turret to achieve such movement. When a first shaft is in the cutting station, it is oriented relevant to the slitting knife such that it can be slit into narrow width tape or ribbons by the slitter. At the same time, a second shaft is located in the loading and unloading station such that a previously slit roll can be removed and a new roll can be loaded into the shaft while the roll on the first shaft is being cut. The turret is then indexed reversing the positions of the first and second shafts.

Dependent claims

An improved roll cutting machine for cutting rolls of sheet material at a cutting station in said machine while simultaneously unloading previously cut rolls from said machine and loading new rolls to be cut thereon at a loading and unloading station of said machine comprising:

a. frame means;
b. a turret assembly mounted on said frame means for rotational movement about a turret axis;
c. multiple spindle shafts mounted on said turret and extending parallel to said turret axis including means to support rolls of material to be slit and chuck means engageable with said rolls of sheet material when mounted on spindle shafts;
d. said turret being rotatable to transport at least one spindle shaft to a cutting station at a first location about said turret axis while simultaneously moving at least one other spindle shaft to a loading and unloading station at a second location about said turret axis;
e. cutting means mounted on said frame for longitudinal movement parallel to said spindle shafts and for movement in a plane perpendicular to said spindle shafts to affect cutting of a roll of material mounted on said at least one spindle shaft in said cutting station;
and
f. drive means for driving said cutting mechanism.
