发明名称 Method and apparatus for making curled decorative grass
摘要 Curled decorative grass having a variety of configurations and methods for making such decorative grass is provided which, because of its increased bulk, can also be used as a packing material, an animal bedding, cat litter, mulch for soil and a media for plants. The curled decorative grass is produced by curling a substantially flat sheet of material and thereafter cutting the resulting curled sheet of material, or by cutting a pre-curled material.
