Supporting element for tobacco industry machine

Abstract

The object of the application is a supporting element ( 3, 3′, 33 ) for a tobacco industry machine designed to support a continuous rod, moving axially ( 2 ) during cutting by a rotationally mounted knife ( 4 ), whereas the supporting element ( 3, 3′, 33 ) comprises an at least partially cylindrical supporting surface ( 10 ) for the continuous rod ( 2 ), having a longitudinal axis ( 11 ), moreover the supporting element ( 3, 3′, 33 ) has a front surface ( 8 ) constituting a cutting surface, characterised in that the front surface ( 8 ) has a depression ( 12, 12′, 42 ).

1 . A supporting element ( 3 ,  3 ′,  33 ) for a tobacco industry machine designed to support a continuous rod, moving axially ( 2 ) during cutting by a rotationally mounted knife ( 4 ), whereas the supporting element ( 3 ,  3 ′,  33 ) comprises an at least partially cylindrical supporting surface ( 10 ) for the continuous rod ( 2 ), having a longitudinal axis ( 11 ), moreover the supporting element ( 3 ,  3 ′,  33 ) has a front surface ( 8 ) constituting a cutting surface, characterized in that the front surface ( 8 ) has a depression ( 12 ,  12 ′,  42 ). 
     
     
         2 . The supporting element of  claim 1  characterized in that the depressed surface ( 13 ,  13 ′) is parallel to the front surface ( 8 ). 
     
     
         3 . The supporting element as in  claim 1  characterized in that the depressed surface ( 13 A) is situated at an angle to the front surface ( 8 ). 
     
     
         4 . The supporting element of  claim 1  characterized in that the width of the depression ( 12 ,  12 ′,  42 ) is equal to or greater than the diameter of the cylindrical supporting surface ( 10 ). 
     
     
         5 . The supporting element of  claim 1  characterized in that the outer part ( 17 ) of the front surface ( 8 ) is conical. 
     
     
         6 . The supporting element of  claim 1  characterized in that the front surface ( 8 ) is perpendicular to the longitudinal axis ( 11 ) of the supporting surface ( 10 ). 
     
     
         7 . A machine ( 100 ) for manufacturing of rods in the tobacco industry provided with a feeding unit ( 200 ) arranged to feed a filling material, a unit ( 300 ) arranged to feed a wrapping material, a continuous rod forming unit ( 400 ), and a cutting unit ( 500 ) provided with a rotating cutting head ( 5 ), characterized in that the cutting unit ( 500 ) is provided with a supporting element ( 3 ,  3 ′,  33 ) according to  claim 1 , situated so that the axis ( 19 ) of the depression ( 12 ,  12 ′,  42 ) is directed convergently with the direction of movement (K) of the knife ( 4 ) mounted on the rotating head ( 5 ).
