发明名称 Method for disacidifying paper products with printings or inscriptions
摘要 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.
