Abstract: A feeder mechanism for a labelling machine to transfer gum from a gumming apparatus to labels at a label supply location, and then to convey the labels to a transfer means. The mechanism includes a feeder member which carries at least one label receiving element mounted on the feeder member by means of a pivot shaft. The feeder member is rotatably driven about an axis and bodily driven in a circular path about a central axis, the feeder member axis being eccentric to said central axis. The pivot shaft is parallel to the rotary axis of its associated feeder member, whereby the movement of the pivot shaft perpendicular to its axial direction describes a looped hypotrochoid. The orientation of each label receiving element about the axis of its pivot shaft is controlled in dependence on the orientation of the feeder member about its rotary axis.
