Abstract
A shoe press in a wire part with headbox and forming wire (4), which shoe press comprises a shoe press roll (14) outside and a counter roll (13) inside the loop of the forming wire, and an outer clothing (15) running outside the forming wire to transfer the web (10) after the extended press nip to a press section, which shoe press roll has a press shoe (32) with a curved, convex inlet surface (35) and a concave press surface (34) into which the inlet surface transits in a point (Ps) intersected by a tangent (Ts) to the inlet surface, whereby the forming wire encounters the counter roll in a point (Pw) intersected by a tangent (Tw) to the counter roll, and wherein the shoe press has an inner belt (20) running in the loop of the forming wire and having water-receiving voids that are open towards the forming wire. In accordance with the invention the press shoe is so arranged in relation to said point (Pw) that said tangent (Ts) and said tangent (Tw) intersect each other at an acute angle alpha that is greater than 2 DEG . The invention also relates to a wire part having such a shoe press.
