ABSTRACT:
A vacuum extrusion line of the horizontal barometric leg type includes a vacuum chamber having an extrusion die at one end and a water baffle immersion cooler at the other end for extracting the extrudate to atmosphere, extrudate shaping and sizing equipment downstream of the die, a large diameter fixed bulkhead at the die, and first and second large diameter movable sections surrounding the shaping and sizing equipment, a smaller fixed section of the chamber. The first section sealing against the second section and the fixed section and telescoping over the fixed section to form a gap with the second section being movable within the limits of the gap. The second section also seals against the large diameter fixed bulkhead. In this manner the downstream equipment can be fully exposed by movement of one or both movable sections and adequate volume and spatial working environment is provided for large through-put. A simplified lock mechanism facilitates the quick opening and closing of the chamber.
