ABSTRACT:
In the forming of an article by blow molding parisons into conformity with cavities of an array of mold sections parisons in the form of tubes are extruded from an extruder into an array of neck molds on a head, the head is moved axially away from the extruder to define the parisons, mold sections are closed about the parisons and the parisons are blown outwardly and a take out mechanism grasps and removes the containers after the mold sections are opened. The apparatus for application of labels to the hollow blown plastic articles includes a label carrier mounted for reciprocating movement between the open mold sections and supporting an array of spaced vacuum pick up devices. The carrier is mounted for reciprocating movement past a source of labels exterior to the blow molding mechanism so that labels are picked up by each of the vacuum pick-up devices, and the carrier is moved between the longitudinally spaced array of mold sections, the vacuum devices are actuated to deliver the array of labels to the cavities of the array of open mold sections at the same time as the take out mechanism is moved adjacent the mold sections to grasp the blown containers so that the labels are delivered with substantially no delay in cycle time.
