ABSTRACT:
A shedding device for moving the shedding rods of a circular weaving machine includes a drive shaft which rotates a cam. The cam has a cam groove which lies in a horizontal plane and receives a plurality of cam follower supports. The supports are pivotally mounted near their center to a cantilever arm which is rotatably mounted about a vertical axis at a location spaced from the drive shaft. The cantilever arms hold the supports at correct angular positions with respect to the cam paths. Vertical swinging and pivoting of the follower supports are transmitted through horizontally moving control rods through cranks which convert the horizontal movement to vertical movement. Clamps are connected to the shedding rods and links connect the clamps to the cranks. A single follower can service a pair of connecting rods which in turn service a pair of shedding rods to save space around the cam.
