ABSTRACT:
A labeling machine of the kind wherein labels are removed one at a time from a stack of labels by a rotating picker provided with axially spaced annular picking surfaces disposed for rotation about an axis parallel to the endmost label in the stack at a distance therefrom such that the annular picking surfaces of the picker are tangent to the plane of the endmost label. The annular picking surfaces contain diametrically disposed slots which are connected to a vacuum as they are moved into engagement with the endmost label and thereafter at a predetermined place in the further rotation of the picker are disconnected to release the label characterized in that there is a needle fixed in each slot with its pointed end flush with the annular picking surface of the picker and with which the portion of the label crossing the slot is held engaged during the period the picker is taking hold of the label and releasing it.
