ABSTRACT:
An apparatus and method for producing and bagging decorative grass, such as Easter grass. The apparatus includes an extruder, a godet, a slitter, a cutter, a bagging assembly and a programmable logic controller. The extruder produces a continuous sheet of material, which is fed by the godet into the slitter and cutter. A thickness gauge is provided between the extruder and slitter to measure the thickness of the sheet of material. The slitter has a row of blades which slit the sheet into a continuous length of slitted material. The cutter includes a rotatable blade which transversely cuts the slitted material into a number of individual filaments. The sheet of material is urged through the slitter and cutter by the godet and an air flow produced by a blower. A foaming agent is injected into the extruder to produce low-density decorative grass.
