To this end, the speed of advancement of the web along its path past an adhesive applicator and thereupon through a severing unit (which subdivides the web into a file of successive uniting bands to be wrapped around filter mouthpieces and plain cigarettes) is temporarily altered when a comparison of first signals denoting detection of successive perforated sections of the running web with second signals denoting the frequency of severing of the web in the severing unit indicates the need for a temporary change of the speed of the web upstream of the adhesive applicator. The latter is installed at a fixed distance from the severing unit.

One marginal portion of the advancing web is coated by an adjustable paster with a variable quantity of adhesive which bonds the overlying marginal portions of the draped web to each other. The quantity of applied adhesive is varied in dependency upon the speed of advancement of the web in such a way that the quantity of applied adhesive is increased when the speed of the web is reduced and that the quantity of applied adhesive is decreased in response to increasing speed of the web. Such quantity can remain constant when the speed of the web reaches a nominal value.

Abstract: The seam of the tubular wrapper for the rod-like filler of tobacco or filter material in a cigarette or filter rod making machine is heated by a first heating element during acceleration of the machine from zero speed to normal operating speed. When the machine reaches the normal speed, the seam is additionally heated by a second heating element whose heating action is more pronounced that that of the first heating element. The first heating element is caused to engage the moving seam when the first increment of adhesive film, which is applied to one marginal portion of the wrapper by a paster, reaches the first heating element. The second heating element is moved into engagement with the seam when the RPM of the prime mover for the filler transporting conveyor reaches a preselected value.
