ABSTRACT:
A 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, minimizing clinging of grass to the hands and clothes of a decorator, thus facilitating handling of the grass, and assuring that the grass will consistently exceed the flammability requirements of the Federal Hazardous Substances Act Regulations in order to be labeled "non-flammable". Processes for making the grass include 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 process, the extruded strips or strands are cooled. In all processes, 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.
