Abstract (en)

1. Device for discontinuously transferring a liquid material on to a surface to be coated, which device has a storage container holding the material, from which container the material is able to be transferred to indentations in the surface of a cliché, a doctor device for cleaning the surface of the cliché after the indentations of the latter have been filled, and an elastic transfer element, called a pad, which can be applied to the surface of the cliché at the beginning of a take-up stroke to receive the material resting in the indentations of the cliché and which pad can then be moved towards and pressed against the surface to be coated for the purpose of transfering the received material, characterized in that the store of liquid printing material (1), the cliché (5) which is in the form of a rotatable roller element (4), the circumference of which is partly immersed in the printing material store and which has indentations (6) which are distributed at intervals in a circumferential direction around the circumference of the roller element, and the doctor device (7) are encapsulted in a container (2) which is closed to the exterior, from which container the circumference of the roller element (4) projects slightly in a radial direction through a supply opening (3), in such a way that this supply opening (3) is closed by means of the projecting section of the roller element except for narrow peripheral areas along the edge of element (10, 11), which encloses the supply opening (3) and the projecting section of the roller element and which can be opened for the application of the pad (12) to the roller surface, is mounted on the container (2).
