Abstract

Four self-adhesive label applicators each capable of printing, with one or two impressions, a label and dispensing that label in the same operational cycle, are intended for hand actuation, but can be power operated. In each embodiment, a web of labels is drawn from a reel in steps corresponding to one label by a feed slide which is in the form of an elongate member having barbs which engage notches of the web downstream of a location at which individual labels are detached from the web by passage over an edge and bending of the web through approximately 180*. Each label, before being dispensed, is printed by operative type facets of at least one print head assembly. The latter include a number of print bands which can be adjusted from externally of the applicator casing by a single knob which selects the band for adjustment and also adjusts the selected band to the required character. The dispensed labels are applied to an article by a semi-circular pad arranged adjacent the dispensing edge. Each of the applicators is operated by a trigger-like member and the applicators as a whole have the appearance of a pistol.

4. An applicator according to claim 3, wherein the printing means comprises two print head assemblies operable to make two separate print impressions on a given label, both said print head assemblies being operable during one operational cycle of the actuating means to print the same label as that dispensed by the dispensing member during that cycle.

5. An applicator according to claim 3, wherein the barbs of the barbed member are arranged as two series to accommodate webs carrying different sized labels.

6.

7. An applicator according to claim 6, comprising a pad of sponge rubber and a plurality of glass balls adhered to the pad, the assembly of balls and pad serving to apply labels to an article.

8. An applicator according to claim 6, comprising an ink pad movable with respect to the printing means, an ink-pad carrier, a roller of the ink pad carrier, and a part of the casing having a notch engageable by the carrier to bring the ink pad into contact with the print means, as the actuating means are operated.

9. An applicator according to claim 8, comprising a label-support platen, said part of the casing having a deeper notch enabling a label on the platen to move into contact with operative type facets of the printing means.

10. An applicator according to claim 6, comprising a label support platen movable by the actuating means linearly and radially with respect to the print means at a print station, said printing means being pivotal so that during printing the operative type facets move tangentially with respect to a label on the platen.

11. An applicator according to claim 10, wherein the label-support and printing platen is integral with the barbed member.

12. An applicator according to claim 6, wherein the printing means comprises two pivotal print head assemblies operable successively on the same label as that dispensed during a given operational cycle.

13. An applicator according to claim 12 comprising means for locking each print head assembly in a predetermined orientation when the actuating means is inoperative.
