Abstract
The metallic portion of a multiple wrap brake band for use in automatic transmissions of motor vehicles is obtained by deforming a circular metallic blank at right angles to its plane into a cup-shaped preform. The bottom wall of the preform is separated from the annular wall and the annular wall is thinned, calibrated, cut, slotted and provided with actuating elements as well as slitted in the circumferential direction to form several neighboring wraps of the multiple wrap brake band. A prefabricated split ring-shaped brake lining is bonded to the internal surface of the annular wall prior to the formation of wraps.
