ABSTRACT:
A positive harness drive mechanism raises and lowers the harnesses of a weaving loom responsive to a control cam that engages the followers of a pair of actuators at all times, regardless of the stroke direction, resulting in a smoother, more controlled stroke than is available in previous devices. The cam utilized herein is a double-landed or split cam mounted on the cam shaft by a pair of clamping collars. The actuators are adjustably connected to a pair of corresponding treadles that in turn lift and lower corresponding harnesses.
