Abstract:
A chill roll for cooling a web, comprising:a) a cylindrical outer shell having an inner and an outer surface, said inner surface of said outer shell having structural projections spaced along a length of said cylindrical outer shell creating channels therebetween, said structural projections extending substantially orthogonally from said inner surface of said cylindrical outer shell so that portions of said inner surface of said cylindrical outer shell define a portion of said channels; andb) a cylindrical inner shell having an inner and an outer surface, wherein a diameter of said inner shell is less than a diameter of said outer cylindrical shell, allowing a coolant material to flow into and out of said channels and contacting said inner surface of said cylindrical outer shell to uniformly cool said outer surface of said cylindrical outer shell,wherein said structural projections are solid non-helical and solid without holes or apertures.
