Apparatus for heating adhesive-containing seams of tubular wrappers for materials of the tobacco processing industry

摘要

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.
