A bottle labeling machine has a rotor on which oscillatingly driven members are arranged in a circular pattern around the rotor axis. A pallet shaft is coupled to each member for being oscillated and for tilting on the member. A portion of each shaft remote from the tilt axis is engaged in a universally movable bearing on a support that is slideable radially inwardly and outwardly relative to the rotor axis. There is a curved glue pallet on each shaft for rolling on a glue roller and a label in sequence as the shafts revolve in a circular path. The slideable support is actuated by a pneumatic piston which is controlled by a valve which is, in turn, controlled by a sensor for sensing whether a bottle will be present at an application station to receive a label. If there will be no bottle there, the piston is actuated and the pallet shaft is tilted to prevent the pallet from contacting the roller and label but oscillation of the shaft is not interrupted. |
