Abstract

A method for correcting the conicity of a tread strip is described. The method includes the steps of extruding a tread profile having a right hand side, a left hand side and a chimney; measuring the thickness of the tread profile at the right hand side and the left hand side; calculating the mass of the tread on the left hand side and the right hand side; and adjusting the location of the chimney incrementally towards the side which is least in mass.

Claims

exact text as granted — not AI-modified

1 . A method for correcting the conicity of a tread strip, the method comprising the steps of:
 extruding a tread profile having a right hand side, a left hand side and a chimney;   measuring the thickness of the tread profile at the right hand side and the left hand side;   calculating the mass of the tread on the left hand side and the right hand side;   adjusting the location of the chimney incrementally towards the side which is least in mass.   
     
     
         2 . The method of  claim 1  wherein the above steps are repeated until the calculated masses are within specification. 
     
     
         3 . (canceled) 
     
     
         4 . (canceled) 
     
     
         5 . A method for correcting the conicity of a tread strip, the method comprising the steps of:
 extruding a tread profile having a right hand side, a left hand side, a cap, a base and a chimney;   measuring the thickness of the tread profile at two or more locations;   calculating the mass of the tread on the left hand side and the right hand side;   determining if the left hand side mass is less than the predetermined left hand side specification and then moving the chimney to the right hand side;   determining if the right hand side mass is less than the predetermined right hand side specification and moving the chimney to the left hand side.   
     
     
         6 . The method of  claim 5  further comprising the step of increasing the chimney width.
