A device for supplying, out of an at least partly disordered amount of flabby rings of an elastic material and with essentially the same circumference in an unloaded rest position, the rings piece by piece in one position exhibits at least two rolls (4, 5) arranged to receive said amount on a reception area of said rolls. The rolls are arranged to define together, through contact surfaces for the rings on their envelope surfaces and their mutual distances, a minimum inner circumference for th erings and to define, in one position, this minimum inner circumference of the rings such that said circumference decreases continuously from the reception area towards a first end of the rolls and is larger than the inner circumference of the rings in the rest position. Means are arranged to bring at least a first one of the rolls to rotate in order to pull the rings along with it, by means of friction, and to feed them from the reception area towards the first end. |
