Abstract

A heat-not-burn tobacco paper cartridge ( 10 ) includes a first rotatable support ( 24 ) and a second rotatable support ( 26 ). The first and second rotatable supports are configured to transfer a strip of tobacco paper ( 28 ) from the first rotatable support to the second rotatable support. The cartridge also includes a heater ( 20 ) positioned between the first and second rotatable supports. The heater is configured to heat a portion of the strip of tobacco paper extending between the first and second rotatable supports.

Claims (63)
