Abstract (en)
[origin: US4862680A] Apparatus for the packaging of cigarettes by successively folding inner and outer wrappers about a hollow open-ended mandrel, plural of the mandrels being supported from a rotary turret which is moved in step-wise fashion, which enables the use of a metalized foil as the inner wrapper. The apparatus establishes communication between a low pressure source and the interior of the mandrel during at least a portion of the wrapper folding procedure with the resulting suction being applied to the inner wrapper via an open end of the mandrel and through an array of holes provided in the side of the mandrel where opposite free ends of the inner wrapper are positioned after folding.
