<p>A novel machine for forming bags from expandable continuous rope net material (50) having a spherical expanding body (22) positioned within the tubular net material to expand the material as the material is drawn around the body (22) and a basin (26) for supporting the body. The machine also has mechanisms to seal (72) the bottom of the expanded material and to adjust the machine to form bags of different lengths (140, 142, 143, 144).</p> |
