Method for producing filter cigarettes

Abstract

A method for the manufacture of filter cigarettes which in longitudinal direction comprise at least two filter portions of different material with the following method steps: endless lines are generated of at least a first and second material and are provided with a wrap first and second sections are cut from the endless lines of different filter material, the sections having a predetermined length the sections are alternatively filed with a predetermined spacing from each other and are continuously wrapped in order to achieve a further endless line the further endless line is divided into double filter sections having end portions and a center portion, the center portion being formed of a first filter section of a first material and the end portions are formed by the half of the section of the second filter material the double filter sections are located between aligned tobacco rods and connected thereto by an end wrap the filter sections are cut in the center.

1 . A method for the manufacture of filter cigarettes which in longitudinal direction comprise at least two filter portions of different material with the following method steps: 
 endless lines are generated of at least a first and second material and are provided with a wrap    first and second sections are cut from the endless lines of different filter material, the sections having a predetermined length    the sections are alternatively filed with a predetermined spacing from each other and are continuously wrapped in order to achieve a further endless line    the further endless line is divided into double filter sections having end portions and a center portion, the center portion being formed of a first filter section of a first material and the end portions are formed by the half of the section of the second filter material    the double filter sections are located between aligned tobacco rods and connected thereto by an end wrap    the filter sections are cut in the center.    
   
   
       2 . The method for the manufacture of filter cigarettes having at least two filter portions of different filter material, with the following method steps: 
 endless lines are manufactured from the first and second filter material, each having a wrap    first and second sections of different material of predetermined length are generated from the first and second endless lines    the sections are alternatively filed and continuously wrapped to form a further endless line    the further endless line is divided into double filter sections having end portions and a center portion, the center portion being formed by the total length of a first section and the end portions are formed by the half of the second sections    the double filter sections are located between aligned tobacco rods forming a space with respect to the associated tobacco rod and are connected to the tobacco rod by a final wrap    the double filter sections are cut in the center thereof.    
   
   
       3 . The method of  claim 1  or  2 , wherein the spacing between the filter portions or the tobacco rod and the associated filter portion, respectively, is between 3 and 6 mm.  
   
   
       4 . The method of one of the  claims 1  to  3 , wherein the wrap is perforated at desired portions.
