摘要： 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.
摘要翻译：一种用于在纸或纸板机中的双线部分中控制电线的装置，其中电线彼此一个移动以脱水存在于电线之间的存货，其中在电线的一侧设置脱水箱，并且其中并排布置的条带数量设置在电线的另一侧，所述条带横贯导线的输送方向延伸，并超过电线的总宽度，并且条带已被布置为压靠在电线上最靠近条带，借助于压力元件，其中所述压力元件设置成在条带和支撑台或等同物之间作用，所述支撑台相对于所述脱水箱固定地安装。本发明的特征在于，对于每个条带（16）已经设置有单独的压力元件（15），其中每个压力元件（15）包括至少两个力供给构件（19,20），其设置在相应的条带和支撑台（13），所述构件（19,20）设置成沿着朝向和离开所述脱水箱的方向移位所述条带（16），所述构件中的第一个（19）已经被布置成在导线的输送方向上抵靠带的前端（25），并且已经将第二个（20）的构件设置成沿着输送方向作用在带的后端（28）上，并且力供给构件（19,20）是可单独控制的，使得一方面钢带（16）抵抗钢丝的压力，另一方面可以调整钢带的顶面与钢丝的角度。
