Abstract
An in-mold label dispenser (42) for supplying labels to a plastic blow molding machine mold (32) whose mold sections open and close along a first direction (A) is disclosed as including a dispensing head (48) mounted for rectilinear movement between withdrawn and inserted positions along a second direction (B) perpendicular to the first direction (A) and supporting at least one label carrier (52) that provides transfer of labels (57) from a label supply (46). An actuator (50) moves the dispensing head (48) and a cam mechanism (58) moves each label carrier (52) between a retracted position and a label transfer position to provide the in-mold label operation. Each label carrier (52) extends from a first end thereof (54) about which pivoting takes place toward the mold to a second end (56) thereof along the second direction (B) in the retracted position and extends from the first end (54) thereof toward the second end (56) thereof along the first direction (A) in the label transfer position to thereby provide accurate registration during the in-mold labeling operation.
