ABSTRACT:
Vibrations that arise during the winding of a coil of wire onto a rotating mandrel are damped by surrounding the coil with a tube such that the tube is spaced from the coil and by supplying fluid to the tube. The tube extends in the axial direction of the coil along at least a part of its length and, due to the spacing between the tube and the coil, conducts fluid such as water in a confined manner towards at least one end of the tube and releases the fluid from the end of the tube, for example in a region of the coil adjacent to and/or remote from the winding of the coil.
