Abstract
A label assembly includes a string of a plurality of non-quadrate (e.g., circular) linerless labels disposed in-line with at least one tie about 0.018-0.030 inches in width connecting consecutive labels in the string together. Each label has a first face with adhesive release material and a second face with pressure sensitive adhesive. The string may be in roll form and taken off the roll and run through a burster for bursting the ties between the labels. The labels may initially also be tied to a matrix from which the string labels is continuously separated. The burster may include high and low speed rolls with a non-stick surface between them and a bursting blade above the non-stick surface. Downstream of the high speed rolls is a sensor, and a mechanism for applying the separated linerless labels to a surface, such as a reciprocating plunger, air blast nozzles, a vacuum cylinder, or a conveyor belt.
