A labeling apparatus and method for applying individual labels onto individual objects moving along a conveyor includes a label delivery mechanism configured to hold a plurality of the labels and operable to deliver individual ones of the labels adjacent to the conveyor. A non-contact adhesive spray
A labeling apparatus and method for applying individual labels onto individual objects moving along a conveyor includes a label delivery mechanism configured to hold a plurality of the labels and operable to deliver individual ones of the labels adjacent to the conveyor. A non-contact adhesive spray applicator including at least one nozzle having a plurality of individual adhesive discharge orifices may be positioned and arranged to discharge adhesive from the orifices onto either the labels or the objects such that the labels may be respectively adhered to the objects.

What is claimed is: 1. A method of applying adhesive to labels, the method comprising: cycling an adhesive applicator open and closed to dispense adhesive from a plurality of orifices spaced from a first label and a second label adjacent the first label; contacting the adhesive with the first label
What is claimed is: 1. A method of applying adhesive to labels, the method comprising: cycling an adhesive applicator open and closed to dispense adhesive from a plurality of orifices spaced from a first label and a second label adjacent the first label; contacting the adhesive with the first label at a plurality of spaced apart locations, each location spaced from a trailing edge of the first label to form a first pattern of adhesive such that the space between the first pattern of adhesive and the trailing edge of the first label is void of adhesive; and contacting the adhesive with the second label at a plurality of locations spaced from a leading edge of the second label to form a second pattern of adhesive such that the space between the second pattern of adhesive and the leading edge of the second label is void of adhesive; wherein the adhesive is applied to the trailing edge of the first label and the leading edge of the second label simultaneously. 2. The method of claim 1, wherein the adhesive applied at the plurality of locations coalesces to form a coating of adhesive. 3. The method of claim 2, wherein the coating of adhesive is an elongate strip of adhesive. 4. The method of claim 1, wherein the adhesive is dispensed at the spaced apart locations as beads or filaments in one of the following forms: a line; swirls; sinusoidal; omega-shaped; saw-toothed; or back and forth. 5. The method of claim 1, wherein the distance the adhesive is spaced from the trailing edge of the first label is sufficiently large to prevent the adhesive from being squeezed out and being exposed when the first label is applied to an object. 6. The method of claim 1, wherein the adhesive is applied in a manner sufficient to eliminate peaks or valleys of adhesive that can be readily visible or felt after the first label has been applied to an object. 7. The method of claim 1, wherein the adhesive is applied to the first label at the plurality of spaced apart locations as small diameter swirls of fine beads of adhesive. 8. The method of claim 1, further comprising: dispensing the adhesive in a corner formed between the trailing edge of the first label and an adjacent edge of the first label. 9. The method of claim 1, wherein the pattern of adhesive approximates the pattern of adhesive applied from a contact slot nozzle or wheel coater on the same area. 10. The method of claim 1, further comprising: applying respective patterns of adhesive to multiple labels at a rate greater than 800 labels per minute. 11. The method of claim 1, further comprising: applying respective patterns of adhesive to multiple labels at a rate greater than 1,000 labels per minute. 12. The method of claim 1, wherein the adhesive is dispensed in overlapping swirls having a diameter in the range of about 5 mm to about 10 mm. 13. The method of claim 1, wherein the adhesive is dispensed with coating weight in the range of about 0.002 to about 0.02 grams/cm2. 14. The method of claim 1, wherein the pattern of adhesive covers 75% to 100% of the area approximating that of a contact slot nozzle or wheel coater. 15. The method of claim 1, further comprising the step of applying adhesive to a leading edge of the first label. 16. The method of claim 1, further comprising the step of applying adhesive to an object receiving the first label. 17. The method of claim 1, further comprising the step of applying the first label to an object. 18. The method of claim 1, wherein the label is delivered from a label delivery mechanism comprising one of the following: a roll-fed labeling mechanism; or a magazine-fed labeling mechanism. 19. The method of claim 1, wherein the plurality of orifices are associated with a first adhesive applicator including a plurality of nozzles. 20. The method of claim 19, wherein said plurality of nozzles are independently operable. 21. The method claim 20, wherein the plurality of orifices of said nozzles are linearly aligned and configured to discharge filaments of adhesive to form a column of closely spaced adhesive filament patterns. 22. The method of claim 19, wherein each nozzle comprises two individual rows of adhesive discharge orifices with a plurality of adhesive discharge orifices in each row. 23. The method of claim 1, further comprising: carrying objects on a conveyor adjacent to the label. 24. A method of adhering individual labels to individual objects, comprising: moving the individual objects along a conveyor; positioning the labels adjacent to the conveyor; intermittently applying adhesive from a plurality of orifices in a nozzle of a non-contact adhesive applicator onto either the labels or the objects as separate adhesive patterns along areas of each label spaced from respective leading and trailing edges thereof; and adhering the individual labels respectively onto the individual objects; wherein spraying separate adhesive patterns further comprises: spraying adhesive from a first plurality of orifices along the leading edge of each label, and spraying adhesive from a second plurality of orifices along the trailing edge of each label. 25. The method of claim 24, wherein intermittently applying adhesive further comprises: applying adhesive filaments in generally back and forth patterns arranged in a linear column. 26. The method of claim 24, wherein intermittently applying the adhesive further comprises cycling the adhesive applicator open and closed in less than about 9 milliseconds. 27. The method of claim 24, wherein intermittently applying the adhesive further comprises applying adhesive to at least 800 labels per minute. 28. The method of claim 24, wherein positioning the labels adjacent to the conveyor further comprises: feeding the labels from a roll onto a vacuum wheel; holding the labels on the vacuum wheel; rotating the vacuum wheel adjacent to the objects; and using the sprayed adhesive to pick the respective labels off of the vacuum wheel and adhere the labels onto the respective objects moving along the conveyor. 29. The method of claim 28, further comprising: cutting the individual labels apart from one another while the labels are held on the vacuum wheel. 30. The method of claim 24, wherein the step of positioning the labels adjacent to the conveyor further comprises: holding the labels in a stack; and using the sprayed adhesive to pick the respective labels off the stack and adhere the labels onto the respective objects moving along the conveyor. 31. The method of claim 24, further comprising: drawing residual amounts of the adhesive back into said orifices upon shut-off of the applicator. 32. The method of claim 24, wherein the step of applying adhesive further comprises: dispensing a plurality of spaced apart beads onto the label, and causing the spaced apart beads of adhesive to coalesce. 33. The method of claim 24, wherein the objects further comprise product packaging. 34. The method of claim 33, wherein the product packaging further comprises containers.
