According to the invention in the crankcase (2) spring (3) is situated which through the thread (4)is tightened. Spring (3) act on spindle (1) which performs pressure in the upper cutter (9) holder (8). The upper cutter (9) nose (7) performs motion through the bolt (5) and that is connected through the screw-nut (6).Bolt (5) propagates through the spindle (14) of the development adjuster of the lower cutter. The upper cutter (9) holder (8) is connected with the spindle (1).Spindle (14) of the development adjuster of the lower cutter through bearing (15) and cam (16) regulates the length of propagation of the upper cutter (9).The engine, through the spindle(17) and chain holder (19) moves the chain (20) and suspension bridge (21) which is directly connected with the spindle (22).Through the bolt (5) motion-adjustment of the contact surface between upper and lower cutter is regulated. In the crankcase (23) which is located in the framework (25) of the machinery, bolt (24) tightens the crankcase (27) of the bearing. |
