Rotary Blow Molding Machine

US Patent:
5840349, Nov 24, 1998
Filed:
Feb 12, 1997
Appl. No.:
8/797936
Inventors:
John M. Brown - Westminster MD
David N. Fiorani - Jacobus PA
John M. Mathy - Stewartstown PA
Rolf E. Weingardt - York PA
Assignee:
Graham Engineering Corporation - York PA
International Classification:
B29C 4936
B29C 4956
US Classification:
425532
Abstract:
A rotary blow molding machine includes a horizontal main shaft with a plurality of molds spaced around the shaft and mounted on the shaft by linear bearings for movement along the shaft. A shaft drive rotates the shaft and molds around the axis of the shaft in the steps and dwells the shaft and molds between steps. Open molds are rotated from a lower container eject position up to a parison capture position and then close on a parison. The closed molds are shifted axially along the main shaft and the parison is blown. Further rotation of the shaft returns the molds to the mold eject position where the molds open and molded containers are ejected downwardly with gravity assist.
