Abstract
This disclosure relates to a demountable rotary cam with upper and lower portions that can be coupled and securely mounted on a rotatable shaft, and can also be demounted and interchanged with other similar eccentrics having different throws. The demountable rotary cam is particularly suited to vary the stroke of the needle bar in a tufting machine and an adjusting means is provided to maintain the proper relationship between the needles and loopers over a range of strokes.
