Abstract

1519417 Cigarette filter BAUMGARTNER PAPIERS SA 29 June 1976 [8 July 1975] 27493/76 Heading A2C A non-enveloped cigarette filter rod is produced by heating a tow of fibrous material to form a rod and then superficially heating the rod by sliding contact with a heated smooth surface to form a smooth skin by fusion. As shown the smooth surface is provided by a smooth walled tube 18 heated electrically or by steam through which the rod passes. The tube is followed by an identical tube 19 supplied with cooling liquid. The initial heating to form the rod is preferably performed by a high frequency device 3, 6 which is followed by a cooling chamber 9. A heat activatable binder is supplied to the tow before each heating stage.
