• an applicator arm configured to feed the label toward the conveyor when the movable track advances the spindle and the product container toward the applicator arm;
• an actuator configured to move between a retracted position and an extended position, wherein the actuator in the extended position is configured to press a leading edge of the label against the product container;
• a gear rack positioned along a side of the conveyor;
• and
• an applicator plate positioned along at least a portion of the gear rack, the applicator plate comprising a resilient material facing a centerline of the conveyor,
