Labelling apparatus

A labelling apparatus for labelling a tray while the tray is conveyed by a conveyor means, comprising:

• a label feeder device configured to place a label onto a top surface of the tray such that the label extends across the tray with a portion of the label exceeding at least one side surface of the tray,
• a first tucker device arranged sidewise to the conveyor means, comprising:
• at least one applicator block rotatably mounted to an axis extending parallel to a conveying direction and the at least one side surface of the tray, and
• a first moving mechanism configured to move the at least one applicator block in a back and forth direction perpendicular to the conveying direction of the tray,
• wherein during labelling the first moving mechanism, in response to a control signal, moves the at least one applicator block from an initial position to a labelling position where the at least one applicator block presses the portion of the label exceeding the at least one side surface of the tray towards the at least one side surface of the tray such that the at least one applicator block follows a shape of the at least one side surface of the tray via a rotational movement of the least one applicator block around a rotation axis;
• and
• a second tucker device arranged above the first tucker device, the second tucker device comprising:
• at least one structure having a free-end following the shape of the at least one side surface of the tray, the at least one structure being positioned adjacent and above the first tucker device;
• and
• a second moving mechanism configured to move the structure in the back and forth direction perpendicular to the conveying direction of the tray;
• wherein the at least one structure of the second tucker device is configured to extend proximate and below at least one protruding portion of the tray.
