Abstract
An electromagnetic device for eliminating a yarn loop during winding of a yarn on a cross-wound bobbin on a spinning machine at a constant speed of the yarn production includes a cylindrical two pole magnet rotatably mounted about a longitudinal axis thereof. A compensatory arm is connected to the two pole magnet. A magnetic core includes two poles situated opposite of each other, with the cylindrical two pole magnet rotatable between the poles. A side of the magnetic core opposite from the two poles passes through a cavity of an electrical coil, wherein the magnetic core is interrupted in the cavity. A two pole permanent magnet is located at the point of the interruption of the magnetic core in the cavity of the electrical coil.
