Patent number: 11701684Abstract: 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.Type: GrantFiled: February 23, 2021Date of Patent: July 18, 2023Assignee: Landa Labs (2012) LTD.Inventors: Benzion Landa, Anton Krassilnikov, Moshe Fahima, Vadim Yakhel

Patent number: 11679408Abstract: There is disclosed a method of printing onto the surface of a substrate, which method comprises i) coating a donor surface with a monolayer of particles, ii) treating the substrate surface to render at least selected regions tacky, and iii) contacting the substrate surface with the donor surface to cause particles to transfer from the donor surface only to the tacky regions of the substrate surface. After printing on a substrate, the donor surface returns to the coating station where the continuity of the monolayer is restored by recovering with fresh particles the regions of the donor surface exposed by the transfer of particles to the substrate.Type: GrantFiled: December 2, 2020Date of Patent: June 20, 2023Assignee: ACTEGA METAL PRINT GMBHInventors: Benzion Landa, Anton Krassilnikov, Moshe Fahima, Vadim Yakhel, Barak Edgar

Publication number: 20230150024Abstract: An apparatus is disclosed for producing flakes, the apparatus comprising: a) a support structure for supporting each of two supply cylinders, made of a first material from which flakes are to be produced, and a fatiguing rod assembly including at least one fatiguing rod made of a second material, each fatiguing rod having a diameter smaller than an initial diameter of the two supply cylinders; b) a compression mechanism for urging the surfaces of the two supply cylinders into contact with each fatiguing rod, and c) a drive mechanism for causing the supply cylinders to rotate while making rolling line contact with each fatiguing rod. The contact pressure between the supply cylinders and each fatiguing rod is set sufficiently high to modify the surface of the supply cylinders by fatigue and result in separation of flakes of the first material from the surfaces of the supply cylinders.Type: ApplicationFiled: April 1, 2021Publication date: May 18, 2023Inventors: Benzion LANDA, Guy FEFFERMAN, Vadim YAKHEL, Yosef SHACHAK, Viacheslav RABINOVICH, Aleksey Elisha LEVIN

Publication number: 20230141815Abstract: 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.Type: ApplicationFiled: April 1, 2021Publication date: May 11, 2023Applicant: LANDA LABS (2012) LTDInventors: Benzion LANDA, Guy FEFFERMAN, Tamar ASHER, Vadim YAKHEL, Yosef SHACHAK, Viacheslav RABINOVICH, Aleksey Elisha LEVIN

Patent number: 10960432Abstract: An apparatus for coating a donor surface that is movable relative to the apparatus with a layer of thermoplastic particles, 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.Type: GrantFiled: November 29, 2016Date of Patent: March 30, 2021Assignee: Landa Labs (2012) Ltd.Inventors: Benzion Landa, Anton Krassilnikov, Moshe Fahima, Vadim Yakhel
