Abstract
The present invention includes a method and apparatus for producing individual folded labels. The method includes the steps of providing a ribbon of labels and folding the ribbon of labels so as to form at least one folded portion. The folded ribbon is subjected to sufficient heat and pressure to set the at least one folded portion. The ribbon of labels is advanced to a cutting device and subdivided into individual folded labels with an ultrasonic cutting device. Immediately prior to cutting, the advance of the ribbon of labels is paused to allow the material to partially melt and flow prior to being subdivided. The corners of the label can also be rounded to provide improved comfort for the wearer.
