METHOD AND APPARATUS FOR APPLYING PRESSURE SENSITIVE ADHESIVE LABELS TO A SERIES OF OBJECTS MOVING IN MULTIPLE COLUMNS

摘要

A method and apparatus for transferring a discrete pressure sensitive label from a plurality of continuous webs of discrete pressure sensitive labels to a continuous series of discrete objects moving in multiple columns wherein the web and labels are mounted to a plurality of label stations removably mounted to a bridge member providing common utilities to each of the plurality of label stations, the web and labels are brought into contact tangentially with a perforated rotating transfer machine mounted on a hub, the web and labels in contact with the perforated rotating transfer means for a portion of its arc of circumference, the label being subjected to a vacuum during rotation while simultaneously redirecting the web away from the perforated rotating transfer means, the label maintaining contact with the rotating transfer means until registration with a pressure port at which point the label is subjected to a pressurized gas flow and is blown from the rotating ring to the object to be labeled when that object is in registration and alignment with the pressure port.
