Method for manufacturing a wapper for use in the manufacturing of cigars

Abstract

Method for manufacturing a wrapper for use in the manufacture of cigars in which a wrapper to be used for enclosing fillers is obtained in that a tobacco leaf ( 1 ) is cut into a number of parallel strips ( 5 ) substantially in longitudinal direction, so in the direction of the mid rib ( 2 ), whereupon the ends ( 9 ) of the strips obtained are connected to each other to one continuous wrapper ribbon ( 10 ). At both ends ( 9 ), the strips ( 5 ) are cut-off across an acute angle (α) to the longitudinal direction, said angle approximately coinciding with the angle enclosed by the side ribs ( 3 ) and the mid rib ( 2 ). The continuous wrapper ribbon ( 10 ) can be wound around the fillers fed as a strand in longitudinal direction, whereupon both longitudinal edges ( 12 ) will be connected to each other The continuous wrapper ribbon ( 10 ) is wound onto a roller ( 11 ), which is fed to the cigar winding machine.

1 . A method for manufacturing wrappers for manufacturing cigars, use being made of a tobacco leaf ( 1 ) which is cut into a number of parallel strips ( 5 ) substantially in longitudinal direction of said leaf ( 1 ), so in the direction of the midrib ( 2 ) thereof; both ends of said strips being cut-off across similar, acute angles (α) in respect to the longitudinal direction, which angle might coincide with the angle enclosed by the midrib ( 2 ) and the sideribs ( 3 ) of said leaf ( 1 ), characterized in that the strips ( 5 ), cut out-off a tobacco leaf ( 1 ), extend themselves substantially between two succeeding sideribs ( 3 ), the ends of several strips ( 5 ) obtained in this way being connected to each other for forming an almost continuous wrapper ribbon ( 10 ). 
   
   
       2 . A method according to  claim 1 , characterized in that the ends ( 9 ) of two strips ( 5 ) are laid on top of each other and are fed between rollers, so that said ends ( 9 ) will be compressed into and be connected to each other. 
   
   
       3 . A method according to  claim 1 , characterized in that on cutting a tobacco leaf ( 1 ) into strips ( 5 ), said strips are scanned and that in case of detecting an irregularity ( 7 ) in a strip, this will be cut transversely at both sides of said irregularity ( 7 ) and the intermediate portion ( 8 ), containing said irregularity will be removed, both ends ( 9 ) of the remaining parts of said strip ( 5 ) being handled in the same way as a normally obtained strip ( 5 ). 
   
   
       4 . A method according to  claim 1 , characterized in that said strips ( 5 ) of wrapper are reinforced with materials that can be processed in the final product, such as so-called “homogenised tobacco leaf” parts, fibres and paper types which can be smoked. 
   
   
       5 . A method according to  claim 4 , characterized in that the strips ( 5 ) of wrapper are combined with binder from homogenised tobacco foil. 
   
   
       6 . A method according to  claim 1 , characterized in that the obtained ribbon of wrapper ( 10 ) is wound around the filler, fed as a continuous strand, in longitudinal direction, whereupon both longitudinal edges ( 12 ) of said ribbon ( 10 ) are connected to each other. 
   
   
       7 . Reel provided with a ribbon of wrapper ( 10 ) wound on it, characterized in that said ribbon is achieve according to the method of  claim 1 . 
   
   
       8 . Cigar, characterized in that it is achieved by using the method according to  claim 5 , said formed continuous strand being cut into part with the desired length.
