Abstract

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. The invention is characterized in that for each strip (16) has been provided a separate pressure element (15), where every one of the pressure elements (15) comprises at least two force-supplying members (19,20) provided between the respective strip and the supporting table (13), said members (19,20) being disposed to displace the strip (16) in the direction toward and away from said dewatering box , that a first one (19) of the members has been disposed to act against the forward end (25) of the strip in the transport direction of the wires and that a second one (20) of the members has been disposed to act against the rear end (28) of the strip in said transport direction, and that the force-supplying members (19,20) are individually controllable so that on one hand the pressure of the strip (16) against the wire and on the other hand the angle of the top surface of the strip against the wire can be adjusted.

Claims (8)

To dehydrate the stock between the wires, one of the wires is operated on top of the other, with a dehydration box on one side of the wire, and on the other side, with a number of strips arranged side by side, the strips conveying the wires. Across the direction of the wire, the strip is arranged to be joined by the pressure member to the wire located closest thereto such that the pressure member is arranged to operate between the strip and the support table and the support table is Means for controlling the wires in a double wire section of a papermaking or cardboard manufacturing machine fixedly placed against the dehydration box, each pressure member 15 being provided for each strip 16, 31, 32. One of the pressure bodies 15 is provided between each strip and the support table 13, 44, 45. At least two force-supply members 19, 20, 21, 22, 23, 24, wherein the members 19-24 are in the reciprocating direction from the dehydration box 10. , 32 are disposed to displace, and the first members 19, 21, 23 are arranged to press against the leading ends 25, 26, 27 of the strip in the conveying direction 9 of the wire. The two members 20, 22, 24 are arranged to press against the rear ends 28, 29, 30 of the strip in the conveying direction 9, the force supply members 19-24 being on the one hand a wire 7. And the pressure of the strip on the other hand and the angle on the other hand to the wire (7) of the upper surface of the strip (16,31,32) are adjustable respectively. The papermaking control device as claimed in claim 1, characterized in that the strips (16, 31, 32) are spaced apart from one another in parallel. 3. The wire control means of claim 1 or 2, wherein the force supply members (19-24) comprise rubber bellows or the like arranged to be controlled with the aid of compressed air. 4. The bellows according to claim 3, characterized in that the two bellows (19, 20) are wedge-shaped in the longitudinal section of the pressure member and are disposed opposite each other to form a rectangular pillow between the strip (16) and the support tables (13, 33). Wire control means of the paper machine. 5. Wire control means for a paper machine as claimed in claim 4, characterized in that the fixing member (37) in the form of a plate is provided between two bellows (19,20). 4. The two bellows (21, 22, 23, 24) have an elliptical shape which is fixed to the strips (31, 32) and the support tables (44, 45), respectively, in the longitudinal section of the pressure member. The strip (31,32) and the support table are partly bonded to each other, so that the strip (31,32) is limited to the support member to move the wire control means of the paper machine. 7. Wire control means for a paper machine as claimed in claim 3, 4, 5 or 6, characterized in that each of said bellows (21, 22, 23, 24) has a length corresponding to the total length of the strip (16). 7. The force supply as claimed in claim 3, 4, 5 or 6, wherein at least two bellows are arranged longitudinally and the bellows 19 ′, 19 ″, 19 ′ ′ have a length corresponding to the total length of the strip 16. Wire control means for a paper machine, comprising a member. ※ Note: The disclosure is based on the initial application.
