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 and 6.2 meters, and winds rolls up to 800 millimeters in diameter on 150-millimeter 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 eight folds). Rolls are automatically removed from the winder with an unloading cart.
