SigmaPro™ - Nozzle Design

Pilot Machine Headbox Nozzle

Precision Control

Larger scale motions in a standard headbox nozzle can align fibers leading to undesirable streakiness in the produced web affecting surface appearance and converting and printing performance. Vanes in the nozzle are provided in all SigmaPro™ headboxes to control turbulence scales and deliver a jet without undesirable streakiness.
