ABSTRACT:
In the forming of an article by blow molding parisons into conformity with cavities of an array of mold sections wherein 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, an apparatus for application of labels to the hollow blown plastic articles which comprises an array of vacuum cups mounted on the head and movable with the head and a mechanism operable to move the vacuum cups outwardly to engage labels on magazines and move the labels inwardly toward the head and to thereafter move the labels outwardly and deposit them in the mold cavities when the head moves adjacent the mold cavities. Provision is made for moving the vacuum cups in a controlled slow manner upon removing the labels thereby obviating problems of removing multiple labels or damaging the labels when then are made of material such as plastic.
