A labeller head using the Bernoulli Effect is suited for applying thin, flexible, pressure sensitive labels (14, 106) of the type having a first, display side and a second, adhesive side, and includes a body having a rigid or resilient support surface (52, 64, 102, 104); a plenum (54) within the body; a plurality of bores (56, 74, 86-90, 114) extending from the plenum through the support surface, the bores being angled with respect to the support surface and arranged in an array so that jets of gas issuing from the array will cause the label to be drawn onto the support surface when the label is presented to the support surface and the first, display side is brought into close proximity of the jets, thereby causing a zone of reduced gas pressure to be formed between the support surface and the first, display side and establishing a pressure differential across the label to hold the label on a film of gas flowing over the support surface; a source of pressurized gas (58) for directing gas into the plenum and through the angled bores; and stops (60, 66, 76, 108-112) for stopping movement of the label relative to the support surface, each of the jets of gas issuing from the support surface being directed at least partially toward the stops. A corresponding method for applying a label is taught.
