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.
Macro Develops Universal Winder Ideal for Geomembranes and Agricultural Films
January 13, 2015
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 meters and 6.2 meters, and winds rolls up to 800 mm in diameter on 150 mm cores. The winder operates at speeds up to 120 meters per minute, 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.
