ABSTRACT:
A tobacco rod is cut with a laser beam using specified time constraints and power levels under essentially atmospheric conditions without utilizing coolant means to prevent charring of the cigarette paper. Additionally, end integrity of cut rods can be increased by treating the tobacco shreds with a material having the characteristic of forming a non-toxic substance capable of bonding the shreds together in the presence of a heat source. Cutting the rod of treated tobacco shreds with a laser beam of specified time constraints and power levels permits the bonding of the shreds in the narrow region bordering the cut, thereby providing the desired increased end strength.
