Collapsing Frame Has Driven Rollers

In the past, a few blown film processors built their own collapsing frames with drive motors on the rollers. The goal was to reduce film stress, eliminate wrinkles, and minimize center sag caused by film friction. Now Future Design Inc., Mississauga, Ont., says it is the first to build a commercial motorized collapsing frame. The firm has delivered two units, the larger one 120 in. tall for producing up to 90-in. layflats. It has 50 rollers per side, with all the rolls on each side driven by a single motor. Future Design will discuss its “Live Roller Collapsing Frame” at the company’s fourth technical symposium for customers, Jan. 24-26 in Fort Lauderdale, Fla. The Live Roller frame will be shown for the first time at NPE 2006 in June.
