ABSTRACT:
Linerless labels are cut or burst from a web by passing the web through infeed and outfeed pairs of rolls with a separator device located therebetween. Each roll pair includes a friction surface for engaging the slick smooth surface of the web and another roll with a silicone elastomeric or plasma-coated surface for engaging substantially without gripping the exposed adhesive side of the linerless label web. In the cutting mode, a rotary blade severs the web against a fixed blade to form the label. The infeed rolls are backed up after each cut to break the adhesive bond between the web and the fixed blade and then reverse to advance the web through the cutting position and into the outfeed rolls for a subsequent cutting operation. The outfeed rolls continue to advance the cut linerless label to a receiving station. In a bursting mode, the web is perforated and a roller breaker bar is disposed between the infeed and outfeed rolls to break the web along the perforations to form the linerless label.
