Method for producing a smokable article

Abstract

Method for operating a rod maker of the tobacco-processing industry. In order to place additives, e.g., flavoring agents, in a cigarette in a location-dependent manner, a tobacco cake or tobacco web is formed from deposited tobacco. Furthermore, an extrudate is formed. The extrudate is applied to the deposited tobacco. The extrudate contains a basic component. An additive is fed to the basic component in a discontinuous manner. The invention also relates to a device for producing a tobacco rod that contains an extrudate.

1 . A method for producing a smokable article comprising: 
 depositing tobacco;    forming an extrudate containing at least one basic component;    applying the extrudate onto the deposited tobacco; and    discontinuously feeding an additive to the at least one basic component.    
   
   
       2 . The method according to  claim 1 , wherein the additive is discontinuously fed to the basic component via a switchable device.  
   
   
       3 . The method according to  claim 1 , wherein the at least one basic component comprises several different basic components.  
   
   
       4 . The method according  claim 1 , further comprising mixing the at least one basic component and the additive in a mixing device to form an extrudate mixture.  
   
   
       5 . The method according to  claim 1 , wherein the extrudate is applied onto the deposited tobacco via a nozzle device.  
   
   
       6 . The method according to  claim 1 , wherein the deposited tobacco contains short tobacco particles.  
   
   
       7 . The method according to  claim 1 , wherein the additive is a flavoring agent.  
   
   
       8 . The method according to  claim 1 , wherein the deposited tobacco is transported at a tobacco conveyor speed, and wherein the extrudate is applied onto the deposited tobacco at a speed essentially the same as the tobacco conveyor speed.  
   
   
       9 . A device for producing a tobacco rod containing an extrudate, comprising: 
 a suction rod conveyor for suctioning tobacco;    an extrusion device for forming the extrudate and for applying the extrudate onto the tobacco; and    a device for discontinuously feeding an additive to a basic component insertable into the extrusion device.    
   
   
       10 . The device according to  claim 9 , wherein the extrusion device comprises a mixing device and the additive is insertable into the mixing device.  
   
   
       11 . The device according to  claim 9 , further comprising a nozzle device for feeding the extrudate to the tobacco.  
   
   
       12 . The device according to  claim 9 , wherein the discontinuous feeding device comprises a switchable valve.  
   
   
       13 . The device according to  claim 12 , wherein the switchable valve comprises a piezoelectric element.  
   
   
       14 . The device according to  claim 9 , wherein the extrusion device includes the discontinuous feeding device.
