Rotary labeling machines can be used to apply one or many labels to the same bottle or container by rotating the bottle 360⁰ during the application. Basically, each bottle is held between a bottle plate and centering bell when it travels on the rotary turret. The rotation of each bottle plate is controlled either mechanically, with cam and steering cross, or electronically with servo motors.
Rotary labelers are perfectly suited for 3, 4 or 5 panel applications because bottles are firmly held, which is helpful to wipe the labels, and we control the rotation/angle of the bottles when labels are applied.
Bottle handling is critical for multi panel label application because the position (or facing) of the label must be perfectly centered to each bottle panel. Also, because the label is wrapped around the corners of the bottles, the bottle rotation must be carefully adjusted to maintain the tension on the label while it is applied.
