Abstract
A roll of shingled, distinct linerless labels is produced by forming a plurality of the distinct labels (each having a substrate, a release coated first face, and a pressure sensitive adhesive coated second face) by transporting a web at a first speed, automatically severing distinct labels from the web, and after severing accelerating the labels to a second, faster, speed so that the labels are conveyed separated and distinct from each other in a first direction. Using a standard rewind the linerless labels are taken up on a formed roll of shingled linerless labels by rotating the roll with an initial tangential velocity component in the first direction at a third speed, slower than the first speed, so that the distinct labels overlap with the second face of each newly added label engaging the first face of at least one label already on the formed roll. The roll shaft is mounted on at least one articulating arm. The build up of labels on the roll is sensed by a sensor, which controls pneumatic cylinders for pivoting the articulating arm about an axis parallel to the roll axis to ensure that the top of the roll is in alignment with the labels when discharged by a transport conveyor…
