Abstract

696,673. Injecting substances into paper pulp webs. KNAGGS, J. Dec. 22, 1950. [Sept. 29, 1949; Feb. 16, 1950 ; Sept. 28, 1950] Nos. 25085/49, 4041/50 and 23806/50. Class 96. [Also in Group XXVIII] Fibrous particles, pigments, dyes, inks, fluorescent materials, or materials which can be condensed or polymerized are injected into wet pulp being formed on a cylinder mould 12, in successive quantities which may register with a watermark. A pattern effect may be produced by reciprocating or interrupting the delivery from nozzles 15, which may be controlled by photo-electric cells or by #-rays and a moving, apertured pattern plate synchronized with the paper production. A stencil plate may be interposed between the nozzles 15 and the pulp. As shown, the material is applied through syringes 16 each having a piston 17 moving against a compression spring 18, the piston and rod having a bore 20 with a spring-controlled ball valve and flexible connexion 21. Delivery through a hypodermic nozzle e.g. of diameter less than 1 mm. may be controlled by an electro-magnet or solenoid 22.
