  • Annular die spiral groove configuration
    Patent number: 8939751
    Abstract: An annular die has a mandrel having a spiral groove formed in a surface of the mandrel that distributes a flow of liquid across the mandrel surface and directs the flow of liquid in a flow direction across the spiral groove and across the mandrel surface. At least a portion of the spiral groove has a cross-section configuration where an interior surface of the spiral groove portion is oriented toward the flow direction as the interior surface extends to and intersects with the mandrel surface. The annular die has particular, but not limited, application as a blown film die.

  • DRIVEN LAYON ROLLER APPARATUS FOR FILM OR SHEET WINDERS
    Publication number: 20140197265
    Abstract: A driven layon roller apparatus for a plastic film or sheet winder is driven in rotation by a magnetic coupling. The magnetic coupling allows for torque to be transmitted to the layon roller of the apparatus to rotate the layon roller while adding little or no inertia and imposing little or no radial force to the layon roller as the layon roller moves position relative to the winder.
