ABSTRACT:
A stationary support device for a paper making machine wire has a movable cover strip, which is formed of a movable support strip and a head strip formed of a hard material on the support strip. The head strip has a leading upstream edge over which the wire slides and has a dewatering surface after the leading edge and which forms a variable angle of inclination with the wire. In the region of its front edge the moveable support strip is connected by a web-groove joint to a rigid support. A bar which is displaceable cross machine is inserted in the rigid support on the rear of the support device. A plurality of obliquely extending grooves are provided in the bar. In each groove there is a slide block which receives the spherical head of a pin. The pin is engaged by its external thread in the internal thread of a square bushing which is fastened in the support strip of the cover strip. The position of the pin can be adjusted parallel to the direction of travel of the wire in the bushing.
