A universal labeling system is provided to perform all of the basic package labeling functions, including applying labels (1) to the side of packages or bottles, (2) to the top, (3) to three sides of a rectangular or similar product, (4) to two opposite sides of a product, and (5) wrapping the labels completely around a round product, such as a bottle. The machine accommodates bottles and packages of many different sizes. Structurally, the universal labeling apparatus includes standardized mechanical power supply arrangements and a heavy duty standardized base having a cross-sectional configuration corresponding to an inverted "T", with the central raised portion carrying a conveyor belt and the two lower side portions of the base carrying longitudinally and laterally adjustable mounts for one or more label applicator heads. At least two standard applicator heads may be used simultaneously, and other equipment which may be provided includes a wrap-around belt, a powered hold-down belt, and an alternative powered top roller. Also, feed screws may be located at desired points along the conveyor belt to bring the product to be labeled up to the conveyor belt speed. The powered top roller has the same diameter and is arranged to be mounted from the same fixture as the top hold-down belt. The drives for the feed screws in the two alternate positions of the feed screws are identical. With the foregoing and other arrangements, a single apparatus may perform a wide variety of labeling functions on a wide variety of types and sizes of packages and bottles.
