Method for designing motion curve of circular loom cam having suspension angle

The present invention relates to a method for designing a motion curve of a circular loom cam having a suspension angle, which takes advantage of the cam to correct a double continuous curve as a basis, and further calculate the best designed range of a suspension angle of the circular loom cam in cooperation with a certain number of thread shafts for the circular loom and angle of a follower component. Thus, the follower component can smoothly travel through the undulated junction of the contour curve trench so as not to lose excessive torque or cause excessively fast raising and falling of the follower component. Accordingly, the breaking of threads on the thread shafts can be avoided as well as the efficiency of production can be also promoted substantially.
