Rod-like article forming apparatus

Abstract

A rod-like article forming apparatus comprises an endless garniture tape ( 10 ) used for forming a tobacco rod (R) with shredded tobacco and a paper web (P), a driving drum ( 12 ) for causing the garniture tape ( 10 ) to travel in one direction, and a plurality of presser rollers ( 34 ) for pressing the garniture tape ( 10 ) against the outer circumferential surface of the driving drum ( 12 ). The presser rollers ( 34 ) increase the contacting force of the garniture tape ( 10 ) with respect to the outer circumferential surface of the driving drum ( 12 ).

1 . A rod-like article forming apparatus comprising a supplying section for supplying a filling material and a wrapping section for wrapping the filling material supplied from said supplying section in a paper web to form the filling material into a rod-like article; wherein 
 said wrapping section includes:    an endless garniture tape used for forming the rod-like article and having a forward portion that extends through said wrapping section and receives the paper web with the filling material and a backward portion continuing to said forward portion,    a rotatable driving drum that causes said garniture tape to travel in one direction and has a wrapping contact area in which said backward portion of said garniture tape is wound around an outer circumferential surface of said driving drum,    a tensioner for applying tension to said garniture tape; and    a presser device for pressing said backward portion of said garniture tape against the outer circumferential surface of said driving drum in said wrapping contact area of said driving drum.    
   
   
       2 . The forming apparatus according to  claim 1 , wherein 
 said presser device includes:    a pressing member for sandwiching said backward portion of said garniture tape between the outer circumferential surface of said driving drum and said pressing member; and    driving means for pressing said pressing member toward the outer circumferential surface of said driving drum.    
   
   
       3 . The forming apparatus according to  claim 2 , wherein 
 said pressing member has a plurality of presser rollers arranged along the outer circumferential surface of said driving drum; and said presser rollers are in rotational contact with said backward portion of said garniture tape.    
   
   
       4 . The forming apparatus according to  claim 3 , wherein 
 said wrapping section further includes:    a guide path for guiding said forward portion of said garniture tape; and    a reduction device for reducing friction resistance that generates between said guide path and said forward path portion of said garniture tape.    
   
   
       5 . The forming apparatus according to  claim 2 , wherein 
 said pressing member has an endless presser belt wound around said winding area of said driving drum through said garniture tape; and said presser belt travels in conjunction with said backward path portion of said garniture tape.    
   
   
       6 . The forming apparatus according to  claim 5 , wherein 
 said wrapping section further includes:    a guide path for guiding said forward path portion of said garniture tape; and    a reduction device for reducing friction resistance that generates between said guide path and said forward portion of said garniture tape.    
   
   
       7 . The forming apparatus according to  claim 1 , wherein 
 said presser device has a suction face formed in the outer circumferential surface of said driving drum; and    said suction face sucks said backward portion of said garniture tape in said wrapping contact area.    
   
   
       8 . The forming apparatus according to  claim 7 , wherein 
 said wrapping section further includes:    a guide path for guiding said forward portion of said garniture tape; and    a reduction device for reducing friction resistance that generates between said guide path and said forward path portion of said garniture tape.
