Patented Jan. 29, 1935 i I t UNITED- STATES PATENTtOFFlCE METHOD AND DEVICE IN THE MANUFAC- TURE OF PAPER- Ivar Wallquist, Gottenborg, Sweden Application March 19, 1934, Serial No. 716,365 In Sweden March 38, 1933 v 2 Claims- (Cl. 92-38) The present invention relates to paper makproduced will adjust themselves so that their ing machines of the Fourdrinier type. It is a longitudinal direction will be substantially paralknown fact that the fibres when flowing out on lel with these currents. the wire will have a tendency to position-them- The device for producing said currents, acselves with their length direction parallel with cording to Figures 2 to 4, comprises one or more the direction of movement of the wire. By such Spr y P pes or the like 30, 3b exten in parallel positioning of the fibres the strength of versely or obliquely above the wire from one side the paper will, of course, be different in different th eo to e o er nd a n ea a O f directionsthereof, fine outlet openings which may. also be formed The invention has for its object to provide by a l n i na fin outletslot with oblique 10 means whereby part of the fibres will adjust thin intermediate Walls guide Plates giving themselves transversely to the direction of movethe medium t b q O fi W dire ti n desired. ment of the pulp, thus increasing the crosswise By Preference, this Outlet Slot is of such a atu e strength of the paper. Another object of the to cause the liquid r'the k tOeOme n invention is to distribute the fibres evenly in the teet w t t e s ee f flbre uspen ion upo th 15 paper, wire in the form of a substantially homogeneous,

Thus, the pulp is treated by the liquid, I do not desire to confine my invention to the vapour or gas on that portion of the wire where fibre distributing device above described but the the fibres still are movable in the water. Those details thereof may be varied within the scope fibres that are influenced by the currents thus of the appended claims.

What I claim is:- 1. A method in the manufacture of paper by a Fourdrinier paper making machine consisting in supplying a mixture of fibres and liquid in the state of a suspenson to the wire of the machine,

. exposing the sheet of fibre suspension on the wire to the action of a flowing medium supplied from an outer source, and giving said medium a so directed movement that in the pulp sheet upon the 10 wire currents are produced in a direction substantially perpendicular to the lengthwise direction of the wire.

2. In combination with a Fourdrinier paper making machine, a device with a row of discharge openings for a flowing medium above the wire, said openings directed obliquely to the upper surface of the wire so that the jets discharged through the openings lie in vertical planes forming angles to the direction of movement of the wire.
