ABSTRACT:
An apparatus for forming a hollow article, wherein all the operations such as shifting and opening/closing of a die are performed by electric actuators such as motors which operate in accordance with a program operation, thus improving the quality of the hollow article as the product. A parison extruded from an extruder is introduced into and held in a die which has been opened by the operation of a die compacting motor. A crosshead associated with the extruder is lifted to draw the parison, and a parison cutting motor operates to cut the drawn parison. Thus, fully automatic production is realized, to ensure high yield of the product.
