Film Extrusion

The ultrasonic WideArray™ edge detection system with blown film or cast extrusion lines has several advantages.  When used with the Micro 4000®NET optional software, the WideArray can oscillate the web, measure web width, as well as monitor the edge position.  This patented system simplifies operation and eliminates the need for motorized edge seeking devises. 

The AccuWeb system guides the web into the slitter and windup while simultaneously controlling bubble pressure to keep the lay-flat web width within preset limits.
