  • Patent number: 6758906
    Abstract: Apparatus for the application of adhesive to one side of a running web of tipping paper for use in filter cigarete makers has a single source of adhesive or two or more sources containing identical or different adhesives, and one or more conduits leading from the source(s) to one or more nozzles which applies or apply one or more films of a single adhesive or of different adhesives to selected portions of the one side of the web. The rate of admission of adhesive(s) to the nozzle(s), including interruption and restarting of admission of adhesive(s), is regulated by one or more valves each having a body receiving a rotary valving element provided with one or more peripheral projections and/or recesses serving to regulate the rate of flow of adhesive toward the single nozzle or the respective nozzles. The rotary elements of two or more valves can constitute disc-shaped sections of a single rotor confined in a valve body common to all valves.

  • Patent number: 6647878
    Abstract: An apparatus for applying printed matter to the running web of cigarette paper or the like in a machine for making rod-shaped smokers' products employs a roller train which transfers printing ink from one or more sources to a rotary carrier of one or more stamps serving to apply trademarks, manufacturer's names and/or other printed matter to longitudinally spaced apart portions of the running web. At least one roller of the roller train has a resilient cylindrical outer layer which contacts the peripheral surface of at least one other roller of the train and surrounds an adjustable rotary eccentric which biases the cylindrical outer layer against the at least one other roller with a force determined by a prestressed coil spring. The eccentric is oscillatable axially against the opposition of a second spring, such as a diaphragm spring.
