Shaped roller for a profiling line

Abstract

A shaped roller for a profiling line, comprising a conical portion ( 2 ) and an end portion ( 3 ), concentric with respect to a rotating axis (Z), wherein the conical portion ( 2 ) is equipped with a vertex section ( 23 ), and wherein the end portion ( 3 ) has a greater diameter than the vertex section ( 23 ) that defines a shoulder from the surface of the first conical portion ( 2 ).

1 . A shaped roller for a profiling line, characterised in that it includes a conical portion ( 2 ) and an end portion ( 3 ), concentric respect to a rotating axis (Z), wherein the conical portion ( 2 ) is equipped with a vertex section ( 23 ), and wherein the end portion ( 3 ) has greater diameter than the vertex section ( 23 ) that defines a shoulder from the surface of the first conical portion ( 2 ). 
     
     
         2 . The shaped roller according to  claim 1 , wherein the end portion ( 3 ) is conical and connected to the conical portion ( 2 ) at the vertex section ( 23 ). 
     
     
         3 . The shaped roller according to  claim 2 , wherein the angle included between the tapers of the conical portion ( 2 ) and of the end portion ( 3 ) is greater than or equal to a right angle. 
     
     
         4 . An operating unit for a profiling line arranged to receive at the inlet a profiled element that has a cross section defined by a lower side (B), two sides (S 1 , S 2 ) and two upper sides (T 1 , T 2 ) sloped upward so as to be converging towards each other, characterised in that it includes two shaped rollers ( 1 ) according to  claim 1 , positioned with the end portions ( 3 ) facing each other and positioned in such a way that the upper sides (T 1 , T 2 ) of the profiled element are in contact with the conical portion ( 2 ). 
     
     
         5 . The operating unit according to  claim 4 , wherein the end portions ( 3 ) are arranged to come into contact with the end edges of the upper sides (T 1 , T 2 ). 
     
     
         6 . The operating unit according to  claim 4 , including adjustment means to allow the movement of the shaped rollers ( 1 ) along one or more horizontal directions and/or along a vertical direction. 
     
     
         7 . The operating unit according to  claim 4 , including a lower roller ( 11 ), arranged to come into contact with the lower side (B) of the profiled element. 
     
     
         8 . The operating unit according to  claim 4 , including two lateral rollers ( 12 , 13 ), arranged to come into contact with the sides (S 1 ,S 2 ) of the profiled element. 
     
     
         9 . The operating unit according to  claim 8 , wherein the lateral rollers (S 1 ,S 2 ) are conical. 
     
     
         10 . The operating unit according to  claim 8 , wherein the lateral rollers (S 1 ,S 2 ) are cylindrical, with a rotating axis that is sloped and adjustable relative to the vertical axis.
