A means for controlling wires in a twin-wire section in a paper or cardboard machine where the wires run one over the other for dewatering stock that is present between the wires, where a dewatering box is provided on one side of the wires and where a number of strips disposed side by side are provided on the other side of the wires, said strips running across the transport direction of the wires and over the total width of the wires, and where the strips have been arranged to be pressed against the wire lying closest to the strips, with the aid of pressure elements, where said pressure elements are disposed to act between the strips and a supporting table or equivalent, said supporting table being fixedly mounted relative to said dewatering box, characterized in that for each strip (16;31;32) has been provided a separate pressure element (15), where every one of the pressure elements (15) comprises at least two force-supplying member (19,20;21,22;23,24) provided between the respective strip and the supporting table (13:44:45), said members (19,20;21,22;23,24) being disposed to displace the strip (16;31;32) in the direction toward and away from said dewatering box (10), that a first one (19;21;23) of the members has been disposed to act against the forward end (25;26;27) of the strip in the transport direction (9) of the wire and that a second one (20;22;24) of the members has been disposed to act against the rear end (28;29;30) of the strip in said transport direction (9), and that the force-supplying members (19,20;21,22;23,24) are individually controllable so that on one hand the pressure of the strip (16;31;32) against the wire (7) and on the other hand the angle of the top surface of the strip against the wire (7) can be adjusted.

A means for controlling wires in a twin-wire section in a paper or cardboard machine where the wires run one over the other for dewatering stock that is present between the wires, where a dewatering box is provided on one side of the wires and where a number of strips disposed side by side are provided on the other side of the wires, said strips running across the transport direction of the wires and over the total width of the wires, and where the strips have been arranged to be pressed against the wire lying closest to the strips, with the aid of pressure elements, where said pressure elements are disposed to act between the strips and a supporting table or equivalent, said supporting table being fixedly mounted relative to said dewatering box, characterized in that for each strip (16;31;32) has been provided a separate pressure element (15), where every one of the pressure elements (15) comprises at least two force-supplying member (19,20;21,22;23,24) provided between the respective strip and the supporting table (13:44:45), said members (19,20;21,22;23,24) being disposed to displace the strip (16;31;32) in the direction toward and away from said dewatering box (10), that a first one (19;21;23) of the members has been disposed to act against the forward end (25;26;27) of the strip in the transport direction (9) of the wire and that a second one (20;22;24) of the members has been disposed to act against the rear end (28;29;30) of the strip in said transport direction (9), and that the force-supplying members (19,20;21,22;23,24) are individually controllable so that on one hand the pressure of the strip (16;31;32) against the wire (7) and on the other hand the angle of the top surface of the strip against the wire (7) can be adjusted.
Claim 3
Dependent Claim
20 words
Means according to claim 1, characterized in that the strips (16;31;32) are placed parallel with and spaced from each other.
Claim 4
Dependent Claim
32 words
Means according to claim 1 or 2, characterized in that said force-supplying member (19,20;21,22;23,24) comprise rubber bellows or equivalent which have been disposed to be controlled with the aid of compressed air.
Claim 5
Dependent Claim
49 words
Means according to claim 3, characterized in that the two bellows (19,20), in section across the longitudinal direction of the pressure elements, are wedge-shaped and placed against and upon each other so that they together constitute a substantially rectangular pillow between the strip (16) and the supporting table (13,33).
Claim 6
Dependent Claim
60 words
Means according to claim 4, characterized in that a fixing element (37) in the shape of a plate is provided between the two bellows (19,20), one marginal part (38) of said fixing element (37) being integrally connected with the supporting table (13,33) and the other marginal part (39) of said fixing element (37) being integrally connected with the strip (16).
Claim 7
Dependent Claim
69 words
Means according to claim 3, characterized in that the two bellows (21,22;23,24), in a section across the longitudinal direction of the pressure elements, have substantially oval shape and are affixed to the strip (31;32), respectively to the supporting table (44;45), and that the strip (31;32) and the supporting table (44;45) partly embrace each other so that the strip (31;32) is only restrictedly movable relative to the supporting table (44;45).
Claim 8
Dependent Claim
27 words
Means according to claim 3, 4, 5 or 6, characterized in that each bellows (21,22;23,24) has a length consistent with the total length of the strips (16).
