ABSTRACT:
Methods and apparatuses for making decorative grass or grass-like product in the form of strips of plastic material of predetermined dimensional characteristics having color, anti-static agents and flame retardants incorporated therein prior to extrusion of the resin thereby preventing rub off of the color and minimizing clinging of grass to the hands and clothes of a decorator. One method and apparatus for making the grass includes an extruder for plastic material and including a film extrusion die or a strand extrusion die. When a film is extruded, the film is cooled and slit longitudinally into strips of predetermined width. In another method, the extruded strips or strands are cooled. In all methods, the plastic strips pass through a slow godet, a drawing oven and a high speed godet to enable the strips or strands to be drawn down in width and thickness without breaking. From the high speed godet, the strips or strands are chopped to a desired length and conveyed to a storage area.
