1. A feeding device comprising:
two suspension bars for suspending an annular body, which are arranged on two parallel axes; two feeding bars, which extend in parallel with the suspension bars and are operable to intermittently move the annular body in a feeding direction inside the annular body suspended from the suspension bars, wherein the two feeding bars are arranged to sandwich the two suspension bars; and a driving mechanism that operates the feeding bars and includes two rotary shafts, a driving member for rotating the rotary shafts, and two cranks fixed to each rotary shaft, wherein each crank has a basal end and a distal end; wherein one of the two cranks fixed to each rotary shaft is fixed to the rotary shaft at the basal end and is coupled to one of the feeding bars to be rotational relative to the feeding bar at the distal end and the other one of the two cranks is fixed to the rotary shaft at the basal end and is coupled to the other one of the feeding bars to be rotational relative to the feeding bar at the distal end. and the feeding bar move from a lower position to an upper position that the suspension bars, during one rotation of the cranks, to lift the annular body from the suspension bars and to move the annular body in the feeding direction and then return to the lower position than the suspension bars.
