Abstract
PURPOSE: To eliminate the change in relative phases and make control sure by fixing a slip-supervising cam to a brake-actuating cam.
CONSTITUTION: When the stop phase of a ram-driving shaft deviates from the top dead point upon decreasing of braking force of the brake and increasing of slips, a brake-actuating cam 13 is shifted against a spring 17 to release a chrysanthemum- shaped fixing mecanism 16. Next, the cam 13 is suitably turned to adjust advance and again it is fixed to the cam shaft 1 by chrysanthemum-shaped fixing. At this time, the engagement of the chrysanthemum-shaped fixing mechanism 20 is maintained by depressing a slip supervising cam 19 by the collar 21 and spring 22 screwed to the boss 13a of the brake-actuating cam 13. The phases of both cams 13, 19 are invariable because they are integrally angle-adjusted with the brake-actuating cam 13. When the axial angle of the slip exceeds the angle phase difference of both cams 13, 19, the cam 19 actuates a switch 18 which in turn emits an alarm command and restart preventing command.
