A label applicator for applying a label to an article which includes a supporting structure and an applicator section mounted on the supporting structure and including a housing adapted to be coupled to a supply of gas under pressure and having a label receiving surface with an opening therein. A label dispenser for dispensing a label onto the label receiving surface where it is retained in at least partial registry with the opening. The applicator section includes a rupturable mask adapted to be in the housing in communication with the supply of gas under pressure and the opening in the label receiving surface, and the mask includes a grid having a plurality of holes extending therethrough and rupturable material blocking at least some of the holes. The rupturable material is rupturable to open selected holes in the grid so that the gas under pressure can flow through the selected holes so that the shape of the gas under pressure acting to blow the label from the label receiving surface can be tailored. A gas distributor is upstream from the mask for making the flow of gas under pressure toward the selected holes even.
