Apparatus wherein a picker provided with an arcuate surface is supported for movement in a circular path at a radial distance from a predetermined center of rotation relative to a glue applying roll, a stack of labels and a transfer turret arranged about said predetermined center characterized in that there is means for effecting movement of the picker along said path and effecting rotation of the picker about the center of its arcuate surface such that said arcuate surface will have exclusively rolling tangential engagement with the surface of the glue applying roll, the surface of the label and the surface of the turret comprising, a fixed sun gear at said predetermined center having portions of different radius of curvature by means of which the rotation of the picker may be accelerated or decelerated, a planetary gear at the center of rotation of the arcuate surface of the picker for effecting its rotation, an idler gear in mesh with the planetary gear movable around the fixed gear in consonance with the planetary gear, means supporting the idler gear for movement relative to the sum and planetary gears as the radius of curvature of the sun gear varies from place to place and a cam for maintaining the idler gear in mesh with the sun and planetary gears as the planetary gear travels around the sun gear.
