IMPROVEMENTS IN THE PROCESS OF MANUFACTURING ARTICLES SIMILAR TO STEMS OF THE TOBACCO INDUSTRY IN MACHINE TO MANUFACTURE THESE ARTICLES AND IN CIGARETTE OR CIGARETTE FILTER

摘要

Cigarettes or cigarette filters are made by forming a filler by feeding continuously at least one web of filler material which has lines of spaced slits extending across the width of the web, the slits in each line being offset from those in adjacent lines; stretching the web so as to open up the slits while distorting out of their original plane the interconnected strip-like portions of the web left between the slits; compressing the web laterally to form a filler; enclosing the thus-formed filler in a wrapper to form a continuous rod; and cutting the continuous rod into individual portions.
