An apparatus is disclosed for coating a 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 at least one spray head for directly or indirectly applying to the surface a fluid stream within which the particles are suspended, a housing surrounding the spray head(s) and defining an interior plenum for confining the fluid stream, the housing having a rim adjacent the surface that is configured to prevent 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 the sprayed fluid and particles suspended in the sprayed fluid. In operation, the suction source extracts substantially all particles that are not in direct contact with the surface, so as to leave only a substantially single particle layer adhering to the surface on exiting the apparatus.

Methods and apparatus for contacting printing via electrostatic force. In one example, an apparatus for contact printing using an ink includes a substrate, a conductive layer disposed on the substrate, and a group of microstructures disposed on the conductive layer. Each microstructure includes a group of conductive porous medium extending from the conductive layer. The apparatus also includes a dielectric layer conformally disposed on the microstructures and configured to electrically insulate the microstructures from the ink during use. The conductive layer is configured to apply a voltage on the group of microstructures to facilitate the loading and dispensing of ink.

The present invention relates to a method for manufacturing structural layers for guiding liquid flow on a porous substrate, by printing onto at least one area of at least one surface of the substrate a printing solution containing an aqueous dispersion of a poly(lactic acid)-based copolymer.

A roller arrangement for printing apparatus comprises a first roller. The first roller comprises a plurality of cells. Each of the plurality of cells receives an amount of a coating material. The roller arrangement further comprises an extractor to remove at least a portion of the coating material from a selected set of the plurality of the cells.

In one method, a piece of nonwoven PET or PP fabric is formed into a tote bag using a bag forming device. Seams of the tote bag are ultrasonically welded using an ultrasonic bag welding device. The ultrasonic bag welding device includes at least one sonotrode. In another method, BOPP film is received and a full-color graphic is printed on the BOPP film for each tote bag using a printer. The printed BOPP film is received from the printer and nonwoven PP or PET fabric is received from a roll of nonwoven PP or PET fabric using a laminator. The printed BOPP film is laminated to the nonwoven PP or PET fabric. The printed BOPP film laminated to nonwoven PP or PET fabric is received from the laminator and a finished version of each tote bag is produced using an ultrasonic bag welding device.
