Stock inlet arrangement for a paper-making machine

A stock inlet arrangement for a paper-making machine, comprising a stock supply conduit;

• a slice;
• a pre-slice flow distribution system communicating with said slice for directing a flow of paper-making stock from said supply conduit to said slice, said system including a manifold extending longitudinally of said slice spaced therefrom and having an inlet side through which stock flows from said conduit in a direction transversely of the elongation of said manifold, a first side wall extending from said inlet side in said flow direction and having a first side wall portion which is convex transverse to said flow direction so as to be tangentially approached by the flowing stock and which is formed with a plurality of outlet openings each having a center axis, and a second side wall transversely spaced from and extending along said first side wall and having a second side wall portion which is so inclined with reference to said first side wall portion that the direction of flow of stock travelling between and guided by said side wall portions includes identical angles with said center axes of the respective outlet openings, said identical angles being between substantially 105.degree. and 155.degree.;
• a plurality of stock distributing tubes each of which communicates with and is coaxial to one of said outlet openings, said tubes converging from said first side wall portion toward said slice;
• and feeding pipes connecting said supply conduit with said inlet side, said feeding pipes being inclined with reference to the elongation of said tubes so as to define therewith an angle between substantially 95.degree. and 135.degree. .
