Patent ID: 7815761

Claim:
A method for forming a cut label on a liner comprising: feeding a web of label material to a cutting station comprising a rotating die head comprising an outer surface comprising flat areas and raised cutting edges above the flat areas, the rotating die head having: a) at least 80% of its outer surface comprising the flat areas between the raised cutting edges, b) multiple raised cutting edges on the outer surface, and c) an internal volume in the die head, the rotating die head characterized by the internal volume in the rotating die head enabling transport of coolant liquid into and out of the volume so as to cool the outer surface of the die head when the coolant temperature is at least 10 C.° cooler than the outer surface of the die head to prevent sticking of adhesive to the cutting edges; and forming a cut label material having an adhesive face on the cut label material; cutting the label material to provide a matrix adjacent a leading edge of the cut label and a trailing edge of the cut label, the distance between the leading edge and the trailing edge defining a length for the cut label; cooling the die head by passing coolant through the internal volume of the die head; stabilizing the leading edge of the label material with respect to the matrix adjacent the leading edge before the trailing edge of the label material leaves the cutting station, the stabilizing being effected without vacuum being distributed over an area comprising at least 50% of the surface area of the cut label; feeding the leading edge of the label material and the matrix adjacent the leading edge of label material into a nip formed between a set of rollers, while the trailing edge of the label is stabilized without vacuum; and feeding a web of liner into the set of rollers against the adhesive face.
