Abstract
An apparatus for heating the seam consisting of an adhesive layer between the longitudinally extending overlapping marginal portions of a running tubular wrapper for tobacco or tobacco filter material has an adjustable elongated infrared heater disposed at a level above and extending in parallel with the path for the wrapper, and a heatable heat transfer member which contacts the seam of the running wrapper. A mirror surrounds the infrared heater and reflects radiant energy toward the heat transfer member. The heater is adjustable in dependency upon the temperature of the seam and/or in dependency upon the speed of the wrapper.
Claims15
Apparatus for conditioning an adhesive-containing longitudinally extending seam of a tubular wrapper confining particular material of the tobacco processing industry and advancing longitudinally along an elongated path, comprising a source of radiant energy spaced apart from said path;
- and means for at least indirectly heating the seam in a portion of said path with radiant energy issuing from said source.
