<p>Docket M-249-C There is disclosed apparatus for printing and applying pressure sensitive labels utilizing a supply roll comprising a composite web having pressure sensitive labels secured to a web of supporting material. The apparatus comprises a print head for printing on successive labels, a delaminator for delaminating successive printed labels from the supporting web, an applicator for applying successive printed labels, a feeding mechanism engageable with the supporting web downstream of the delaminator for feeding the composite web to present partially delaminated labels to the applicator, and an arrangement for operating the print head and the feeding mechanism in sequence. A brake mechanism is effective upon completion of the sequence for applying braking force to the composite web upstream of the delaminator to prevent the web from advancing toward the delaminator during application to a printed label by the applicator. The brake mechanism includes cooperable parts controlled by the print head for movement into and out of braking cooperation with the composite web and one of the cooperable parts includes a rotatably mounted roll.</p> |
