Abstract
Apparatus for producing hollow plastic articles in a hollow die with a relatively smaller reciprocating punch therein. Plastic material is fed from a nozzle aligned with the die, into the die about the punch, the punch being initially advanced into the opening of the die and retracting as the plastic is introduced from the nozzle. When the plastic introduction is completed, then the nozzle is slid laterally on the die until the duct of the nozzle is out of registry with the die and the nozzle thus closes the die. Then the punch is advanced within the closed die to compress the plastic material into the space between the die and the punch.
