ABSTRACT:
An apparatus for preparing a drawn heat-set plastic hollow vessel, which comprises a rotary member having a plurality of openable-closable blow-forming and heat-setting molds and preform-supporting mechanisms corresponding to said molds, a preform supply mechanism for supplying a preform maintained at a drawing temperature into the mold of the rotary member at the opening position and a vessel withdrawal mechanism for withdrawing a drawn and heat-set vessel from the mold of the rotary member at the opening position, wherein the rotary member comprises a mold-heating mechanism for maintaining the molds at a heat-setting temperature through the entire rotation course of the rotary member, an opening and closing mechanism for closing the molds after passage through the position of the preform supply mechanism and opening the molds before arrival at the position of the vessel withdrawal mechanism, a sealing member capable of reciprocating relatively to the preform supported by the preform support mechanism while having a sealing engagement with the mouth portion of the preform, a hollow drawing rod arranged concentrically with the sealing member to reciprocate so that the drawing rod is inserted into the preform and drawn out therefrom.
