An improvement in labeling machines of the type disclosed in Wesley U.S. Pat. No. 3,278,359 in which provision is made for labeling nesting type buckets or pails in which the pair of rotating support rollers that form the cradle on which the bucket or pail is rotatably mounted for application of a label thereto is modified by providing the non-adjustable support roller that overlies the label feed guide with an index roller seat in which rides the pail rim at the pail closed end; the other laterally adjustable support roller has a similar index roller seat that cooperates with the index roller seat of the first mentioned roller to cradle the pail closed end, and a positioning disc is disposed adjacent the other end of the adjustable support roller against which the pail external surface rides when the pail is supported for labeling purposes by the support rollers, with such positioning disc being proportioned in external diameter relative to the amount of circumferential wrap the label to be applied to the pail is to have as to the pail external surface, to dispose the pail side wall surface in substantial flush relation with the said label outfeed angle. The pail when applied to the roller cradle involved is resiliently held against the support rollers thereof by a roller rectractably engaged with the inside of the pail, whereby the pail rotates with the support rollers of the supporting cradle therefor, for application of the label thereto.
