Abstract
A device for separating and dispensing strips of self-adhesive articles, such as postage stamps, labels and other materials formed in strips. Elongated strips of these self-adhesive articles are wound into rolls and supported upon a waxy backing layer and require separation for use. The separating dispenser may be a two-part assembly having a housing and a closure for the housing, with a slot therethrough, which the elongated strips of self-adhesive articles are dispensed and advanced through complementary guide pins that frictionally hold the dispensed material. The device can separate a backing layer from stripped material when the backing layer and the stripped material are directed along different paths and only the backing layer is advanced through the guide pins. The mechanism of the present invention advantageously permits efficient production and operation. In addition to being economical and easy to use, this invention has obvious reliability advantages.
