In labeling equipment, a label is ordinarily picked up from a stack of labels 2 by a vacuum label wheel 4, which carries the label into contact with an envelope, magazine or other suitable piece 6 to be labeled provided from a supply 8.

To obviate the need for an external vacuum supply, the vacuum wheel can be provided with an internal vacuum pump. A flexible tube 10 mounted within the wheel acted upon by a rotatable roll 12, the axis of which is stationary, causes the tube 10 to be progressively flatened as the label wheel rotates, thereby producing a low pressure area communicating with the vacuum port 14 as the tube thereafter assumes its normal, non-flatened configuration.
