BIODEGRADABLE AND EDIBLE FEED PACKAGING MATERIALS

摘要

Molding apparatus (10) is provided which allows use of a particulate non-liquid molding material (121) to produce a variety of articles, such as frustoconical barrel segments (122). The apparatus (10) includes a female mold segment (18) including generally annular inner and outer sidewalls (70, 76) and a complemental male mold section (20) having an annular sidewall unit (30). In use, a molding material (121) is placed between the sidewalls (70, 76) and the section (20) is shifted so that it telescopes within the section (18); this compresses the material (121) to a desired final shape, which is then hardened to yield the final product (122). An optional wear insert (26) can be used with female mold section (18), which can be replaced as needed and assists in cleaning of the apparatus (10).
