Apparatus for applying self-adhesive labels

An apparatus for applying self-adhesive labels comprises:

• a supporting base for at least one reel of a ribbon that supports a plurality of self-adhesive labels, means of feeding said ribbon to a head for applying said self-adhesive labels, and a device for taking up said ribbon, said application head extending along a direction of extension that defines a path direction for the ribbon, wherein said application head can move on command about an orientation axis in order to vary its own direction of extension with respect to the unwinding direction of said ribbon from said reel, said feeder means comprising at least one redirection roller the rotation axis of which can rotate on command, with respect to said reel, about an adjustment axis that is substantially parallel to said orientation axis in order to bring the direction of extension of said ribbon at said application head substantially parallel to the direction of extension of said application head, said feeder means comprising at least two redirection rollers, which are supported by said application head and the longitudinal axes of which can rotate on command, with respect to said supporting body, about a respective adjustment axis that is substantially parallel to said orientation axis, said at least two redirection rollers comprising an end roller, which is supported by said application head and has a rotation axis thereof arranged substantially at right angles to the direction of extension of said application head, and at least one intermediate roller arranged upstream of said end roller with respect to the advancement direction of said ribbon, the rotation axis of said intermediate roller having an intermediate position between the axis of said reel on which said ribbon is wound and the rotation axis of said end roller.
