Abstract
(EN)
FIELD: technological processes. SUBSTANCE: an apparatus for coating the printing plates for intaglio printing is provided; it comprises a vacuum chamber having an inner space provided to accommodate at least one printing plate for intaglio printing, which shall be coated, a vacuum system connected to the vacuum chamber provided to create a vacuum in the inner space of the vacuum chamber, and a system of physical vapor deposition (PVD) provided for implementation of wear resistant coating material in a vacuum on the surface of the engraved printing plate for intaglio printing. System physical vapor deposition comprises at least one target with coating material comprising a source of wear coating material to be deposited on the surface of the engraved printing plate for intaglio printing. The vacuum chamber is disposed so that the printing plates for intaglio printing, which shall be coated; it is disposed substantially vertically in the inner space of the vacuum chamber so that its etched surface is facing the at least one target with coating material. Apparatus for coating a printing plate for intaglio printing also comprises a movable supporting element disposed in the inner space of the vacuum chamber and provided for supporting and moving the cyclic printing plate for intaglio printing in front of and past the at least one target with coating material. EFFECT: coating apparatus enables reliable and effective coverage of the printing plates for intaglio printing layer of the wear coating material, and is easy to operate and maintain. 20 cl, 8 dwg

Предложен аппарат для нанесения покрытия на формные пластины для металлографической печати, содержащий вакуумную камеру, имеющую внутреннее пространство, предусмотренное для размещения по меньшей мере одной формной пластины для металлографической печати, на которую должно быть нанесено покрытие, систему создания вакуума, соединенную с вакуумной камерой, предусмотренную для создания вакуума во внутреннем пространстве вакуумной камеры, и систему физического осаждения из паровой фазы (ФОПФ), предусмотренную для осуществления осаждения износостойкого материала покрытия в условиях вакуума на гравированную поверхность формной пластины для металлографической печати. Система физического осаждения из паровой фазы содержит по меньшей мере одну мишень с материалом покрытия, содержащую источник износостойкого материала покрытия, подлежащего осаждению на гравированную поверхность формной пластины для металлографической печати. Вакуумная камера расположена так, что формная пластина для металлографической печати, на которую должно быть нанесено покрытие, расположена, по существу, вертикально во внутреннем пространстве вакуумной камеры так, что ее гравированная поверхность обращена по меньшей мере к одной мишени с материалом покрытия. Аппарат для нанесения покрытия на формную пластину для металлографической печати содержит также подвижный несущий элемент, расположенный во внутреннем пространстве вакуумной камеры и предусмотренный для поддержания и циклического перемещения формной пластины для металлографической печати впереди и мимо по меньшей мере одной мишени с материалом покрытия. Предложенный аппарат для нанесения покрытия обеспечивает возможность надежного и эффективного покрытия формных пластин для металлографической печати слоем износостойкого материала покрытия, а также прост в эксплуатации и техническом обслуживании. 19 з.п. ф-лы, 8 ил.
