摘要： The invention relates to a device for determining the target point of an observation unit. The device comprises a target area; a scan line projector, which projects at least two non-parallel scan lines and moves said scan lines across the target area; a control unit, which controls the movement of the scan lines; and an optical target point detector, which provides a target point signal to the control unit if a scan line is detected. The control unit determines the position of each scan line 03 in the target area at the time of the detection by the target point detector and outputs the virtual intersection of the two scan lines at said time as the target point. The invention further relates to a method for determining the target point of an observation unit.

摘要： This device, preferably formed as a dual paper machine, has according to a preferred embodiment two endless screens, mainly a lower screen (21) and an upper screen (22). The lower screen (21), on which is formed a paper web, and the upper screen (22) are moved together in the lower part of a dehydration cylinder (25) arranged in the upper screen. Both screens (21,22) are unrolled from the rising lower quadrant of said cylinder (25) and are laid on the upper part of the support cylinder (26) arranged in the lower screen (21). The bandage of the dehydration cylinder (25) has hollows which absorb water from the screens along their arcs of contact with the cylinder and which project the water towards the inside of the loop formed by the screens of the cylinder. In the feed direction of the screens and downstream of the support cylinder (26), there is arranged a receiving container (36) for the projected water. The container has a curved covering wall (40) which extends opposite the feed direction of the screens up to the interstice formed between the dehydration cylinder (25) and the screens (21,22). The reception container (36) is divided into two chambers (44,45) which extend transversally to the screens and which have separate side discharge conduits. The water supplied into the main chamber (45) through the covering wall (40) is deviated by means of blades (52) towards the direction of the discharge conduit.
