Printing device for labels in labelling machine - in which colouring material is moved by centrifugal action on distribution rollers

摘要

Label printing device used in a labelling machine by which a colouring material is removed from a storage container and distributed by rollers and placed on printing types. The colouring material is enclosed in a top air tight container from which it flows by capillarity into a bottom container. The downwards directed colouring material is by adhesion held together in drops which are subjected to a centrifugal force when the labelling machine is running. Due to the centrifugal force the drops are moved in radial direction on an inclined surface of the bottom container. During their upwards movement along the inclined surface they reach an opening through which the drops of colouring material are guided on the distribution rollers.
