1. A pulley for transmitting rotational motion between first and second rotating shafts of a continuously variable transmission with a belt, the pulley being fixed to the first rotating shaft, the pulley comprising:

  • first and second parts being traversable closer to or further away from each other,each of the first and second parts mounted onto the first rotating shaft of the continuously variable transmission,each of the first and second parts having a skewed surface which interfaces with the belt and collectively forms a groove,a laser induced friction surface applied to a portion of the skewed surfaces of the first and second parts which engage the belt during operation of the continuously variable transmission,the first and second parts fabricated from a metallic material, andthe laser induced friction surface comprising patterned kerfs applied to the skewed surfaces of the first and second parts,wherein each of the patterned kerfs comprise recast material deposited about the kerf to increase a coefficient of friction of the skewed surfaces compared to skewed surfaces without the laser induced friction surfaces,wherein the recast material comprises a plurality of peaks and valleys, andwherein the recast material deposited about each kerf is generated by a roughing laser beam vaporizing a portion of an outer surface of the skewed surface.
