14656 PARISON HANDLING ASSEMBLIES & METHODS FOR HANDLING PARISONS ABSTRACT OF THE DISCLOSURE A parison handling assembly receives tubular plastic parisons from a random bulk storage, orients the parisons, and feeds the parisons in a controlled manner to one or more blow molding machines. Parisons are stored in the random bulk storage and fed at a controlled rate by a metering apparatus to a parison orienter which orients the parisons into a closely grouped arrangement wherein the parisons are both upright and side-by-side, The parisons are fed from the parison orienter to a parison escapement mechanism which holds the parisons temporarily. The escapement mechanism is actuated to release parisons into a parison transporter depending on the production demands of the individual blow-molding machines. Released parisons, from the parison escapement mechanism, move along the parison transporter to be pushed axially into stuffer tubes. The stuffer tubes hold the parisons in properly oriented, end-to-end relationship for delivery to the actual loading station of the blow-molding machine.
