ABSTRACT:
A web of cigarette paper, imitation cork or similar sheet-like material which is used as a tubular wrapper for rod-like fillers of tobacco or filter material or which is subdivided into discrete uniting bands for plain cigarettes and filter plugs is coated with one or more layers of an aqueous dispersion of hotmelt. The layer or layers are thereupon heated to expel water therefrom before the web is draped around one or more rod-shaped smokers' products. The layer or layers are thereupon heated to a temperature at which the dried hotmelt melts, either before or during and/or subsequent to draping, to activate the hotmelt. If the web is converted into uniting bands prior to draping around groups of coaxial rod-shaped articles, and if the filter plugs of filter cigarettes are to be provided with holes for admission of atmospheric air into the column of tobacco smoke, the web is provided with two spaced-apart layers of aqueous dispersion of hotmelt prior to subdivision into uniting bands and the holes for admission of atmospheric air are formed in the two layers subsequent to expulsion of liquid.
