Abstract: Systems and methods for manufacturing synthetic yarns for synthetic turf. The systems and methods include rollers for advancing a plastic sheet forward through a manufacturing process. The plastic sheet is cooled and heated on opposing sides by alternating temperature rollers to pre-form the plastic sheet such that subsequent synthetic yarns made from the sheet will have a curled shape. The plastic sheet is then cut longitudinally by a plurality of slitting blades along the length of the sheet to form a plurality of single strand synthetic yarns. A drawing device then draws and stretches the single strand synthetic yarns to a desired width and thickness, wherein the drawing device includes a drawing oven for heating the yarns, and a plurality of drawing rollers for pulling and stretching the heated yarns. The final product drawn yarns comprise sealed, smooth yarns with desirable rounded edges and a curled tip.
