Abstract
An in-mold labeling apparatus includes a label transfer assembly having a pair of label carriage each with two label heads and two suction cups for engagement with labels from a magazine or a source of labels and placement of the labels in mold cavities of a blow molding machine. A continuously rotating drive member operates a first rotary drive to raise and lower the label transfer assembly between the label pick up and label discharge positions while dwelling the assembly at the two positions during label pick up and transfer. The drive member also operates a second rotary drive to extend and retract the dwelled label transfer heads at the two positions to pick up labels and then place the labels in mold cavities.
