Abstract
The present invention relates to a method as well as a device for deacidification treatment of inscribed or printed paper products (in the following called “books” for short), in which method the pages of the book to be treated are fanned open by means of an opening jet and, by means of an agent jet, the agent is injected between the fanned-open pages of the book; in this, for reducing the flow resistance prevailing between the individual pages 4 of the book 3, a suction takes place on the opposite side. In addition, provision is made for a slot-shaped, curved opening-jet nozzle 12 for generating a suitable opening jet 11.
Claims40
Method for deacidification of inscribed or printed paper products in which method the pages of said inscribed or printed paper products to be treated are fanned open by means of an opening jet blowing through the individual pages from the underside towards the topside, or vice versa, and, by means of a jet charged with the agent the agent is injected between the fanned-open pages of said inscribed or printed paper products, characterized by the fact that the opening jet (11) displays a curved shape when viewed in section.
Method for deacidification of inscribed or printed paper products in which method the pages of said inscribed or printed paper products to be treated are fanned open by means of an opening jet blowing through the individual pages from the underside towards the topside, or vice versa, and, by means of a jet charged with the agent the agent is injected between the pages of said inscribed or printed paper products, characterized by the fact that for producing the agent jet an atomizer gas and the agent in fluidized form are premixed in a mixing chamber (17) of the agent nozzle (10) and subsequently introduced into said inscribed or printed paper products.
Device for deacidification treatment of printed or paper products with at least one support for the fanned-open positioning of said inscribed or printed paper products to be treated, at least one opening jet nozzle (12) for fanning open said inscribed or printed paper products, as well as at least one agent-jet nozzle (10), characterized by the fact that an additional suction nozzle (13) is positioned on the side of said inscribed or printed paper products opposite that of the opening-jet nozzle (12).
