Device for applying a label to a bottle or a similar object

摘要

A device for applying a label to a bottle or similar cylindrical object by rotating the same has a supply conveyor for moving the objects to at least one rotatable screw arranged horizontally over the supply conveyor for spacing and moving the objects at uniform speeds. A rotatable vacuum drum is positioned next to the supply conveyor, which drum is adapted to carry and apply labels to the objects. Conveyors are provided at both sides of the object adjacent and opposite the vacuum drum for rotating the objects before and during labelling. The downstream end of the screw is positioned at a predetermined distance from a plane perpendicular to the axis of the screw and the plane extends through the axis of the vacuum drum. The downstream end of the screw also extends into at least one of the conveyors. The conveyor situated adjacent the vacuum drum is coupled to the drum and extends and moves against the linear direction of movement of the objects.
