摘要： Fastening of a profile bar to adjustment spindles at a discharge opening of a head box of a paper machine. A series of fastening holes or recesses are made into one edge of the profile bar and provided with chamferings. In the end of the adjustment spindles situated next to the discharge opening, a recess is provided with a series of screws being fitted in one side thereof. These screws are provided with ends coresponding to the chamferings in the fastening holes of the profile bar. A second set of screws coaxial with the first set of screws are provided in an outer wall of the recess, with inner ends of the second set of screws being provided with parts corresponding to the outer chamferings of the fastening holes in the profile bar. The inside or first set of screws can be locked in a position such that, when the profile bar is attached into connection with the inside screws by the holes and the chamferings thereof, a center plane of the profile bar coincides with an axial center plane of the adjustment spindles. The profile bar can be locked into position by the outside or second set of screws.
摘要翻译：在造纸机头盒的排出口处将型材紧固到调节主轴上。一系列紧固孔或凹槽被制成轮廓条的一个边缘并且具有倒角。在位于排放口旁边的调节主轴的末端，设置有一系列螺钉安装在其一侧的凹部。这些螺钉设置有与轮廓杆的紧固孔中的倒角对应的端部。与第一组螺钉同轴的第二组螺钉设置在凹槽的外壁中，第二组螺钉的内端设置有与轮廓杆中的紧固孔的外倒角对应的部件。内部或第一组螺钉可以被锁定在这样的位置，使得当型材杆通过孔和其倒角与内螺纹连接时，型材的中心平面与轴向中心平面重合调整主轴。轮廓杆可以通过外部或第二组螺钉锁定到位。
