It's rare when a product comes along that really is different and obviously better than the available alternatives.  It seems that most new developments in the web handling industry are "me-too" products.  This is not the case with Menzel's Polyband Expander.  It is not a slat expander or a bow roll, but a better and more efficient system than the other two combined.  The Menzel reputation has been built on offering solution through innovation and the Polyband Expander is a perfect example.

Standard Features:
  • Unit is constructed of a 6" diameter cylindrical aluminum extrusion.  Equidistant grooves are machined into the cylinder to house the 30 highly elastic polymer bands.
  • Bands run from end to end and are connected to individually adjustable cams which provide greater flexibility in spreading.
  • The amount of spreading is fully adjustable while the line is running, unlike the bow roll, the Polyband does not overstretch the web in the middle.
  • The Polyband Expander is driven and functions by the movement of the web itself.
  • Operates smoothly, evenly, and quietly.
  • There are no lubrication points in the web area, assuring clean operation.
  • Individual elastic cords are easily replaced without the need for special tools, making maintenance a snap.
  • The Polyband functions with web wrap from 30° to 180°, allowing an easy fit at nearly any spot on your machine.  And because the entire web touches the roll, you are assured of consistent, wrinkle-free results.
Optional Features:
  • Cylinder drive sheave can be attached when driven roll is required for gentle handling of delicate fabrics.  (A-SECTION BELT, TIMING BELT, CHAIN-DRIVE SPROCKET.)
  • Special construction available for high speed (up to 1500 FPM) applications.
  • For high-temperature requirements, a special sillicone elastic band can be adapted to the standard roll.
