Abstract
A labeling apparatus is for applying labels to articles advanced along an article conveyor. The labeling apparatus may include a frame to be positioned adjacent the article conveyor, and a labeler carried by the frame. The labeler may include a housing, a rotary bellows wheel carried by the housing, and bellows carried by the rotary bellows wheel. The rotary bellows wheel and adjacent portions of the housing may define a porting arrangement for selectively connecting the rotary bellows wheel to a fluid flow to selectively control internal fluid pressure for the bellows so that each bellows is movable between a retracted label pick-up position and an extended label-applying position and so that a peak negative internal fluid pressure is applied at the label pick-up position and a peak positive internal fluid pressure is applied at the label-applying position.
