Zusammenfassung: | Extrusion blowing, employing two or more units contg. blowing-moulds, and one or more extrusion heads. Each unit moves between two positions. The positions are: (A) a reception position, where the opened blowing-mould receives the preform. (B) A different, extraction position (B), where the blown vessel is taken out of the blow-mould. The blowing-mould is ≥ two-piece separable. It closes to form a cavity in the shape of the hollow-ware vessel, actuated by a drive, which also opens it. The vessel is blown under internal pressure into the cavity. |
