Abstract

An in-mold labelling system for automatically applying labels to the interior of blow mold halves prior to the placement of preforms within such blow mold halves; the preforms are blown to form containers with a label attached thereto. The labelling system is mounted on a rotating drum having a plurality of blow mold sets. A label magazine is also mounted on the drum and preferably carries two stacks of labels. Associated with each label stack is a support shaft having at one end a transverse arm which, in turn, carries a suction cup for pick-up and deposit of the label. The other end of the support shaft extends through a drive mechanism for rotating the support shaft so as to swing the transverse arm to a first position for label pick-up from the magazine and then to a second position for label deposit in the blow mold.
