LABELING APPARATUS WITH HOUSING HAVING FLUID PUMP AND RELATED METHODS

摘要

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, bellows carried by the rotary bellows wheel and a fluid pump within the housing and connected in fluid communication with the rotary bellows wheel to provide a fluid flow for the bellows so that each bellows is movable between a retracted position and an extended label-applying position.
