Abstract

Machinery for producing oriented blow-moulded containers involves a turret with one or more mandrels for supporting a tubular parison and gripping it by the neck. The mandrels can turn successively via a parison mould tool anda parison conditioning tool to a position where a deep mould allows the parison to be stretched longitudinally before being dilated. Stretching is effected by driving the mould tool coaxially over the mandrel, to force the neck clamps along guide bars away from the mandrel head and towards the turret axis. After the parison has been stretched, dilated and chilled, the mould tool is withdrawn and parted to allow the moulding to be moved by the turret to an ejection station. The machinery design is simpler than for equipment involving turrets with reciprocating mandrels to obtain parison extrusion.
