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 bod
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.

Apparatus for acquiring and holding a thin, flexible, pressure sensitive label of the type having a first, display side and a second, adhesive side opposite said first, display side, said apparatus comprising: a body having a support surface; a plenum within said body; a plurality of bores extending
Apparatus for acquiring and holding a thin, flexible, pressure sensitive label of the type having a first, display side and a second, adhesive side opposite said first, display side, said apparatus comprising: a body having a support surface; a plenum within said body; a plurality of bores extending from said plenum through said support surface, said bores being angled with respect to said support surface and arranged in an array so that jets of gas issuing from said array will cause said label to be drawn toward and across said support surface when said label is presented to said support surface and said first, display side is brought into close proximity of said jets, thereby causing a zone of reduced gas pressure to be formed between said support surface and said first, display side and establishing a pressure differential across said label to hold said label on a film of gas flowing over said support surface; means for directing a flow of gas into said plenum and through said angled bores; means for presenting at least a portion of said label along a path of movement across said support surface; for permitting said jets to engage said first, display side and draw said label toward and across said support surface; and then for releasing said label to move with said film of gas across said support surface; and at least one stop abutment associated with said body for stopping movement of said label across said support surface and for holding said label on said film of gas in a position for accurate application to an article to be labeled, at least a portion of said jets of gas issuing from said support surface at least partially toward said stop abutment to cause said label, after release by said means for presenting, to reposition from said path to said position for accurate application against said stop abutment while said label is held on said film of gas, all of said portion of said jets being covered by said label when said label is positioned against said stop abutment.
