In one aspect, a vacuum drum assembly for use with a labeling apparatus includes apertures for supporting labels on an outer surface using vacuum pressure. The vacuum drum assembly may include air distributors for providing vacuum pressure to selected apertures to accommodate various lengths or widths of labels. The vacuum drum assembly may also be adjustable to vary the spacing between apertures to accommodate various lengths of labels.

1. A vacuum drum assembly for applying labels to objects, comprising: a generally cylindrical drum body having an outer peripheral surface and an inner peripheral surface;a plurality of apertures in an outer circumferential surface of the vacuum drum assembly, said apertures defining locations on said outer circumferential surface for supporting labels thereon;a plurality of passages in said drum body, between said inner peripheral surface and said outer peripheral surface, at fixed circumferential locations thereon, said passages adapted to communicate with a vacuum source;each said aperture in fluid communication with one of said passages such that vacuum pressure may be developed at said apertures through said respective passages;the vacuum drum assembly being adjustable to vary at least one of an axial configuration or a circumferential configuration of said plurality of apertures in fluid communication with the vacuum source, such that the vacuum drum assembly is adapted to support differently sized labels on said outer circumferential surface; andat least one first ring received over said outer peripheral surface of said drum body and defining at least a portion of said outer circumferential surface of the vacuum drum assembly;wherein said plurality of passages in said drum body comprises a plurality of first passages; andwherein said plurality of apertures comprises a plurality of first apertures in said first ring, each said first aperture communicating with one of said first passages;said first ring being rotatable around said outer peripheral surface of said drum body while said first apertures are in communication with said first passages to thereby adjust the circumferential locations of said first apertures relative to said drum body. 2. The vacuum drum assembly of claim 1, further comprising: at least one second ring received over said outer peripheral surface of said drum body and defining at least a portion of said outer circumferential surface of the vacuum drum assembly; andwherein said plurality of passages in said drum body further comprises a plurality of second passages;wherein said plurality of apertures further comprises a plurality of second apertures in said second ring, each said second aperture communicating with one of said second passages;whereby rotation of said first ring adjusts the circumferential locations of said first apertures relative to said second apertures to accommodate a desired length of label. 3. The vacuum drum assembly of claim 2, wherein: at least one of said first passages or said second passages are arranged in a plurality of respective, generally axially aligned rows, said rows spaced in a circumferential direction around said drum body. 4. The vacuum drum assembly of claim 3, further comprising: a plurality of bores through said drum body, extending from said first axial end toward said second axial end, each said bore adapted to be in fluid communication with the vacuum source;each of said first passages communicating with one of said bores, and each of said second passages communicating with another one of said bores for fluid communication with the vacuum source; andan air distributor disposed in each bore, each said air distributor adjustable to selectively provide fluid communication through said bore and between one or more of said first passages or said second passages in said respectively associated row and the vacuum source. 5. The vacuum drum assembly of claim 4, wherein each said air distributor comprises: an elongate, cylindrical distributor body, said distributor body having an outer circumferential surface; andat least one recess formed into said outer circumferential surface of said distributor body, said recess configured to provide fluid communication between one or more of said apertures in said associated row of apertures as said distributor body is rotated within said bore. 6. The vacuum drum assembly of claim 5, wherein said recess comprises plural slots formed into said outer circumferential surface and extending axially along said distributor body. 7. The vacuum drum assembly of claim 2, further comprising: raised lands on said first and second rings and in registration with said first and second apertures. 8. The vacuum drum assembly of claim 2, further comprising: raised lands on said first and second rings and in registration with said first and second apertures. 9. The vacuum drum assembly of claim 7, wherein said raised lands correspond to positions on the vacuum drum assembly for receiving the leading and trailing edges of a label, respectively. 10. A vacuum drum assembly for applying labels to objects, comprising: a drum body having an outer peripheral surface;a plurality of apertures in said outer peripheral surface and defining locations on said outer peripheral surface for supporting labels thereon; anda plurality of passages in said drum body, said passages adapted to communicate with a vacuum source;each said aperture in fluid communication with one of said passages such that vacuum pressure may be developed at said apertures through said respective passages;the vacuum drum assembly being adjustable to vary at least one of an axial configuration or a circumferential configuration of said plurality of apertures in fluid communication with the vacuum source, such that the vacuum drum assembly is adapted to support differently sized labels on said outer peripheral surface;wherein said drum body has a first axial end and a second axial end, and wherein said plurality of apertures are arranged in a plurality of generally axially aligned rows, said rows spaced around said outer peripheral surface, the vacuum drum assembly further comprising:a plurality of bores through said drum body extending from said first axial end toward said second axial end, each said bore associated with one of said axially aligned rows of apertures and adapted to be in fluid communication with the vacuum source, andan air distributor disposed in each bore, each said air distributor adjustable to selectively provide fluid communication between one or more of said apertures in said associated row of apertures and the vacuum source through said bore;wherein each said air distributor comprises: an elongate, cylindrical distributor body, said distributor body having an outer circumferential surface, andat least one recess formed into said outer circumferential surface of said distributor body, said recess configured to provide fluid communication between one or more of said apertures in said associated row of apertures as said distributor body is rotated within said bore; andwherein said recess comprises plural, spaced-apart slots formed into said outer circumferential surface and extending axially along said distributor body.
