Patent

CA 2150702

Linerless labels are manually dispensed by mounting a roll of the labels for take-off from a stationary shaft. A polygon-cross-section foam core is provided between the shaft and the label roll toprovide a brake drag effect to prevent excess label unwind. The non-adhesive face of the labels passes from the roll around a freely rotating guide roller with a non-stick surface which ensures consistent wrap of the labels and no scuffing of the non-adhesive face as the labels are dispensed. The labels pass from the guide roller to a tear surface having a first smooth, coarse, ribbed or grooved pattern metal portion which has low adhesion to the adhesive of the labels, but will stick to the labels sufficiently to provide an anchoring force to a lable greater than the force necessary to tear along a perforation of the label, and a second non- stick surface portion. The tear surface preferably is the exterior surface of the cylinder or tube, and the non-stick surface is provided by a plasma coating on a portion of the metal cylinder or tube exterior surface.

Des étiquettes sans support détachable sont distribuées à partir d'un rouleau d'étiquettes monté en vue du prélèvement sur un arbre stationnaire (20). Un noyau de mousse de section polygonale est prévu entre l'arbre et le rouleau d'étiquettes afin de fournir un effet de freinage par traînée qui empêche un déroulement excessif des étiquettes. La face non adhésive des étiquettes quittant le rouleau passe autour d'un galet de guidage (34) tournant librement et pourvu d'une surface empêchant l'adhérence qui assure un enroulement constant des étiquettes sans que leur face non adhésive soit éraflée pendant leur distribution. Les étiquettes passent du galet de guidage à une surface de déchirement (37) qui possède une surface empêchant l'adhérence (39) de telle sorte que la surface de faible adhérence crée une force d'ancrage suffisante pour que l'étiquette puisse être déchirée le long d'une perforation qu'elle présente.
