ABSTRACT:
A drum continuously rotating on a vertical axis carries at least two pairs of label transfer members spaced circumferentially around its axis and rotatably connected to the drum on vertical axes. One of the transfer members in each pair is a pick-up member and the other a delivery member, with the pick-up members alternating with the delivery members. The pick-up members are continuously rotated on their axes in one direction while the delivery members are rotated in the opposite direction at the same speed. Each of the transfer members has a label-contact surface provided with a vertical row of air inlets, the contact surface of each pick-up member facing away from the axis of the drum when that member is in pick-up position at the label magazine, at which time suction is applied to the air inlets to withdraw a label from the magazine. The suction is subsequently released while suction is applied to the air inlets in the delivery member of the same pair when their contact faces are directly opposed to each other, whereby to transfer the label from the pick-up member to the delivery member. The contact surface of the delivery member faces away from the axis of the drum when that member is in delivery position beside the label-applying apparatus. The suction at the delivery member is released after the label has been delivered to the label-applying apparatus. The rotations of the drum and delivery members combine to move the contact surface of the delivery member that is in delivery position forward at the same speed as the adjoining surface of the label-applying apparatus.
