         12 . The machine of  claim 11 , wherein:
 the skate roller assembly is mounted by spindles at eleven locations in the skate roller MA assembly A adjustable and fixed with the skate rollers vertically parallel to a wide face of the skate roller bar in eleven locations starting from an entry end and ending at an exit end of the machine.   
     
     
         13 . The machine of  claim 12 , wherein:
 the idle roller is mounted by a protruding spindle to the skate roller bar with an orientation aligned to the skate roller assembly in at least three locations between second and third, fifth and sixth, and eighth and ninth locations of the skate roller assemblies both in the skate roller MA assembly A adjustable and fixed parts.   
     
     
         14 . The machine of  claim 11 , wherein:
 the skate roller assembly is mounted by spindles at eleven locations in the skate roller MA assembly B fixed with the skate rollers in eight locations starting from an entry end and ending at an exit end of the machine;   the two skate idle crease rollers placed such that one is before the first skate roller assembly, and the second is after the eighth location of the skate roller assembly; and   the two idle roller assemblies placed such that one is between third and fourth and second is between fifth and sixth location of the skate roller assembly.
