ABSTRACT:
A winding apparatus is provided for the layering of thin elongated material, especially hot-rolled wire in loop-like windings, in which a doubly or spatially curved laying tube whose longitudinal axis forms a cone-shaped rotation body and whose peripheral speed at the outlet opening matches the entrance speed of the material rotates around a rotation axis, in which case the laying tube is also curved in the peripheral direction of the superficies of the rotation body, the improvement comprising the superficides of the rotation body being curved in an essentially concave manner in accordance with a cycloid beginning at the entrance opening of the laying tube with its vertex, the length of the cycloid resulting from a half-rotation of a rolling circle generated from top to bottom of said rotation body, and that the curvature of the laying tube in the peripheral direction of the superficies is specified by a simultaneously occurring substantially half-rotation of said rotation body around its rotation axis.
