ABSTRACT OF THE DISCLOSURE Tobacco smoke filters and methods and means for making same wherein the products have both internal and external cavities, with the external cavities being of a limited mature so as to provide a substantially smooth outer surface for attaching conventional plug wrap without the need for attaching conventional plug wrap without the need for an internal glue line. The external cavities comprise from about 5 to no more than 50 percent of the total outer surface of the inner filter member, preferably between about 20 and 30 percent. This enables the inner filter member to pro- vide substantially uniform support to the overwrap. The outer cavities may be in the form of elongated, discrete, grooves, a knurled-like pattern or a con- tinuous helical groove. The resultant filter has high filtration and correspondingly low pressure drop charac- teristics, with the technique of manufacture being such as to permit higher production speeds than with the prior art, resulting in lower manufacturing costs. The outer grooves are formed by various mechanical ironing or grooving techniques, by crimping or by utilizing jets of steams.
