Abstract

A method and unit for folding a sheet of wrapping material about a group of cigarettes includes feeding the cigarettes and wrapping material into a pocket of a wrapping conveyor so the sheet of wrapping material folds into a U inside the pocket and has an outer end projecting from the pocket, and an inner end resting on a lateral wall of the cigarettes. The method also includes folding the inner end 90° so the inner end is perpendicular to the lateral wall. The method also includes folding the outer end into an L inside the pocket, onto the lateral wall of the cigarettes and onto the inner end perpendicular to the lateral wall so as to superimpose the outer end and the inner end and impart a tubular shape to the sheet of wrapping material. The method also includes heat sealing the outer and inner ends together.
