A device for the positive feeding of a yarn, particularly for knitting machines, having a rotatable storage drum adapted to have a yarn supply wound thereonto and withdrawn therefrom over a rim thereof, a stationary yarn guide element located below the rim and outwards of the periphery of the rim in a center plane extending through the axis of rotation of the storage drum, a yarn guiding element located in the yarn path between the rim and the yarn guide element and formed with a yarn guiding edge, and a stoppage sensing element having a portion extending parallel to a tangent of the rim transversely of the yarn path between the yarn guiding edge and the yarn guide element, and being mounted for pivotal movement under the action of a biasing force. The yarn guiding edge extends substantially rectilinear and parallel to the portion of the stoppage sensing element, and its end extends beyond the center plane and is adjoined by a yarn support edge which is located beyond the center plane and gradually recedes in a direction parallel to the plane of the rim or extends obliquely away therefrom.
