Abstract: An apparatus is disclosed for printing images on generally cylindrical objects. The apparatus comprises an impression station that includes a movable imaging surface for bearing an ink image; and a transport mechanism for advancing the objects through the impression station, comprising a drive member rotatably connected to a plurality of rotatable mandrels, each for mounting a respective one of the objects, the transport mechanism being configured to cause each object to rotate during passage through the impression station such that, within a nip region of the impression station, the surface of the object makes rolling contact with the imaging surface, thereby causing the ink image to be impressed on the object. An impression platen is provided opposite the imaging surface within the nip region, the impression platen being configured to apply a force, directly or indirectly, to the objects to ensure rolling contact between the objects and the imaging surface.

Abstract: A method is disclosed for producing flakes of a first material, the method comprising: a) supporting two supply cylinders of the first material and a fatiguing rod assembly, that includes at least one textured fatiguing rod, so that each fatiguing rod is sandwiched between the two cylinders, each fatiguing rod having a diameter smaller than an initial diameter of the two supply cylinders and being made of a second harder material; b) urging the surfaces of the two supply cylinders into contact with each fatiguing rod; and c) causing the supply cylinders and the fatiguing rod(s) to rotate while making rolling line contact with one another; wherein the supply cylinders and each fatiguing rod are urged against one another with sufficiently high contact pressure to modify the surface of the supply cylinders by fatigue and result in separation of flakes from the surfaces of the cylinders.

Abstract: A printing assembly for thermal transfer printing is disclosed. The assembly comprises at least one first printing system comprising a transfer member having an imaging surface on the front side, a coating station at which a monolayer of thermoplastic particles is applied to the imaging surface, an imaging station at which electromagnetic radiation (EM) is applied, optionally via the rear side of the transfer member, to selected regions of the imaging surface to render the particles coating the selected regions tacky, a transfer station at which only the regions of the particles coating that have been rendered tacky are transferred to a substrate to form an adhesive image; and at least one more downstream printing system. The transfer member includes on its front side an EM radiation absorbing layer, the imaging surface being formed on, or as part of, the absorbing layer, and on its rear side a body which can optionally be transparent to EM radiation.

Abstract: A method of coating a donor surface with a layer of thermoplastic particles, the method comprising: providing a supply of the thermoplastic particles suspended in a fluid, applying the fluid to the donor surface, in a manner to cause the particles suspended in the fluid to form a substantially continuous particle coating on the donor surface, causing fluid flow within an interior plenum of a housing over a portion of the donor surface partially disposed therein, the fluid flow being of sufficient magnitude to entrain particles that are not in direct contact with the donor surface and insufficient to entrain particles that are in direct contact therewith; and extracting from the plenum fluid and particles which are not in not direct contact with the donor surface, so as to leave adhering to the donor surface a particle coating that is substantially only a single particle deep.

Abstract: Method and apparatus for coating selected regions of a surface of a substrate with a film are disclosed. A cyclically moveable transfer member has an imaging surface which is coated with individual particles formed of, or coated with a thermoplastic polymer, and substantially all particles that are not in direct contact with the imaging surface are removed so as to leave a uniform monolayer particle coating on the imaging surface. Selected regions of the imaging surface are exposed to radiation to render the particles tacky within the regions, and the coated imaging surface and the substrate are pressed against one another to cause transfer of only the particles rendered tacky in the coating, such that the transferred particles form a film on the substrate. The monolayer on the imaging surface of the transfer member is replenished with fresh thermoplastic particles and the cycle repeats.

Abstract: An apparatus is disclosed for transferring a pattern of a composition containing particles of an electrically conductive material and a thermally activated adhesive from a surface of a flexible web to a surface of a substrate. The apparatus comprises: respective drive mechanisms for advancing the web and the substrate to a nip through which the web and the substrate pass at the same time and where a pressure roller acts to press the surfaces of the web and the substrate against one another, a heating station for heating at least one of the web and the substrate prior to, or during, passage through the nip, to a temperature at which the adhesive in the composition is activated, a cooling station for cooling the web after passage through the nip, and a separating device for peeling the web away from the substrate after passage through the cooling station, to leave the pattern of composition adhered to the surface of the substrate.

Abstract: A printing apparatus and method are disclosed for printing on three-dimensional objects. The apparatus employs an offset printing process in which an ink image is deposited onto an intermediate transfer member (ITM) having the form of a flexible endless belt. After drying of the ink image on the ITM, the ITM transports the dried ink image to an impression station having a nip at which the ITM is compressed between an object and an impression surface, so that the dried ink image is transferred from the ITM to the object. The impression surface may form part of a stationary anvil, the ITM sliding relative to the impression surface during passage through the impression station. To optimize throughput, the velocity of the ITM relative to the surface of the object at the impression station may be greater than the velocity of the ITM relative to the imaging station.

Abstract: An apparatus for coating a donor surface that is movable relative to the apparatus with a layer of metallic particles or particles having a metal-like appearance and reflectivity, the particles adhering more strongly to the surface than to one another. The apparatus comprises an application device to apply to the donor surface a fluid stream within which the particles are suspended, a housing surrounds the application device forming an interior plenum for confining the fluid stream, the housing prevents egress of particles from a sealing gap defined between the rim of the housing and the surface to be coated, and a suction source connected to the housing to extract from the plenum excess fluid and particles. In operation, the suction source extracts substantially all particles that are not in direct contact with the donor surface, leaving substantially a single particle layer adhering to the donor surface upon exiting the apparatus.
