Macro Develops Universal Winder Ideal for Geomembranes and Agricultural Films
Film and sheet extrusion systems supplier Macro Engineering & Technology Inc. (Canada) has developed a winder that can wind either wide sheeting or narrow films on center; a configuration that is ideal for winding materials produced on geomembrane/ agricultural film swing lines.
The winder is a center-turret type with two winding modes: a fully automatic mode for agricultural films and a semi-automatic mode for geomembranes where operators need to manually attach the sheet to the core. The machine accommodates webs with thicknesses between 30 and 2500 microns, widths between 1.0 m and 6.2 m, and winds rolls up to 800 mm in diameter on 150 mm cores. The winder operates at speeds up to 120 m/min, can wind slit rolls (multiple ups), folded films and gusseted films (up to 8 folds). Rolls are automatically removed from the winder with an unloading cart.
Macro recently installed this winding system, in the form of two winders in back-to-back configuration, to an unnamed film and sheet producer in Europe. For more information visit www.macroeng.com.
