Abstract
Abstract Filter cigarettes with multiplex filter mouthpieces wherein at least one filtering element constitutes an unwrapped filter plug having a reinforced porous peripheral layer are produced in a machine which is equipped with a perforating device for tubular envelopes connecting the mouthpieces to the respective plain cigarettes, or with a device for making holes in the web of wrapping material which is subdivided into uniting bands. The holes are provided in those portions of tubular envelopes which surround the reinforced porous peripheral layers. Filtering elements which constitute unwrapped filter plugs may be disposed at the free ends of the mouthpieces or adjacent to the plain cigarettes.

Claim 2
Dependent Claim
93 words
A smokers' product, particularly a filter cigarette, comprising coaxial first and second rod-like sections one of which includes a tobacco filler and a tubular wrapper surrounding said filler, the other of said sections comprising a plurality of coaxial filter plugs at least one of which comprises an unwrapped rod consisting of filter material and having a reinforced porous peripheral layer; and a tubular envelope surrounding said other section and that portion of said one section which is adjacent to said other section, said envelope having a perforated portion surrounding said one filter plug.
Claim 3
Dependent Claim
31 words
A product as defined in claim 1, wherein said other section comprises a plurality of filter plugs which comprise unwrapped rods consisting of filter material and having reinforced porous peripheral layers.
Claim 4
Dependent Claim
23 words
A product as defined in claim 1, wherein another of said filter plugs comprises a tubular wrapper which is surrounded by said envelope.
Claim 5
Dependent Claim
26 words
A product as defined in claim 3, wherein said other filter plug further comprises a filler which is surrounded by said wrapper and includes absorbent material.
Claim 6
Dependent Claim
18 words
A product as defined in claim 4, wherein said absorbent material is carbon in pulverulent or granular form.
Claim 7
Independent Claim
101 words
A method of making smokers' products of the type wherein a rod-like tobacco-containing section is disposed end-to-end with a rod-like filter mouthpiece having several filter plugs which are disposed end-to-end and at least one of which consists of unwrapped filter material having a reinforced porous peripheral layer, comprising the steps of placing the mouthpiece and the section end-to-end; perforating a portion of an adhesive-coated uniting band; and draping said uniting band around the mouthpiece and around that portion of the section which is adjacent to the mouthpiece, including convoluting the perforated portion of the uniting band around the one filter plug.
Claim 8
Independent Claim
101 words
A method of making smokers' products of the type wherein a rod-like tobacco-containing section is disposed end-to-end with a rod-like filter mouthpiece having several filter plugs which are disposed end-to-end and at least one of which consists of unwrapped filter material having a reinforced porous peripheral layer, comprising the steps of placing the mouthpiece and the section end-to-end; perforating a portion of an adhesive-coated uniting band; and draping said uniting band around the mouthpiece and around that portion of the section which is adjacent to the mouthpiece, including convoluting the perforated portion of the uniting band around the one filter plug.
Claim 9
Dependent Claim
67 words
A method as defined in claim 6, further comprising the step of coating one side of the uniting band with adhesive prior to said perforating step, said draping step including convoluting the band around the mouthpiece and around the adjacent portion of the tobacco-containing section in such a way that the adhesive-coated side of the uniting band is located at the inside of the resulting tubular envelope.
Claim 10
Dependent Claim
32 words
A method as defined in claim 6, further comprising the step of coating one side of the uniting band, with the exception of said portion of the uniting band, with an adhesive.
Claim 11
Independent Claim
94 words
A method of making smokers' products of the type wherein a rod-like tobacco-containing section is disposed end-to-end with a rod-like filter mouthpiece having several filter plugs which are disposed end-to-end and at least one of which consists of unwrapped filter material having a reinforced porous peripheral layer, comprising the steps of placing the mouthpiece and the section end-to-end; draping an adhesive-coated uniting band around the mouthpiece and around that portion of the section which is adjacent to the mouthpiece; and perforating that portion of the draped uniting band which surrounds the one filter plug.
Claim 12
Independent Claim
94 words
A method of making smokers' products of the type wherein a rod-like tobacco-containing section is disposed end-to-end with a rod-like filter mouthpiece having several filter plugs which are disposed end-to-end and at least one of which consists of unwrapped filter material having a reinforced porous peripheral layer, comprising the steps of placing the mouthpiece and the section end-to-end; draping an adhesive-coated uniting band around the mouthpiece and around that portion of the section which is adjacent to the mouthpiece; and perforating that portion of the draped uniting band which surrounds the one filter plug.
Claim 13
Dependent Claim
