What are the requirements when winding Kevlar rope onto the glass tempering furnace roller ?

Use 12mmX3.5mm Kevlar rope to wind glass tempering furnace rollers to make sure every two adjacent rollers are winded clockwise and counterclockwise respectively with 40mm screw pitch. The rotating direction of the last roller’s rope closed to the tempering furnace unloading table is set to be clockwise to unify the winding standard.
