The present invention relates to an apparatus and a method for preparing labels for application to containers, wherein glue is applied in a variable glue image directly onto a glue application surface of at least one label by means of a controllable glue printer.

There is provided a sheet feeding apparatus which can perform appropriate separation corresponding to the type of a sheet without being newly provided with an actuator which changes the separation action of a separation unit. For this purpose, a separation unit 105 includes a first inclined part 105a-1 and a second inclined part 105a-2 each having different inclination angles, and selects, in accordance with the type (stiffness, thickness, or the like) of a sheet to feed, either one of the first inclined part 105a-1 or the second inclined part 105a-2 as an inclined part used in separating sheets by lifting/lowering a tray 101, and separates sheets, so that appropriate separation can be performed in accordance with the type of a sheet with a simple configuration.

A banknote separation device includes a banknote separation wheel set and a reverse wheel set. The reverse wheel set includes a reverse wheel component, a reverse wheel set rotation shaft, a first fixing frame and a second fixing frame. Two ends of the reverse wheel set rotation shaft are fixed on two mounting side plates respectively, the first fixing frame and the second fixing frame are respectively fixedly connected at two ends of reverse wheel component. The first fixing frame is provided with two lash adjusting threaded holes and a first lash adjusting screw, the second fixing frame is provided with a second lash adjusting threaded hole and a second lash adjusting screw cooperating therewith, and radial clearances between two ends of the reverse wheel component and the banknote separation wheel set are adjusted respectively by the two lash adjusting screws.
