Device in a machine for preparau00c7u00e7o of rotau00c7u00e7o, for example, a structure of retrau00c7ao, machine for carding, combing machine or similar, with a system of drawing.The present invention relates to a device in a machine for the preparation of rotation, for example, a structure of retraction, a machine for carding, combing machine or similar, with a system of draw frame for drawing at least a dealer of fiber with cylinders of sys EMA of drawing forming pairs of rollers for drawing.Which has transmission devices of energy to power the cylinders of the drafting system and having a drive motor, the drive of the cylinders system of drawing being performed from different sides.In order to achieve success with a relatively small number of elements, and carry out a substantial improvement in efficiency, the motor drive has two drive elements for rotating.Actuation of the at least one pair of rollers being carried from one side by the first actuating element and the actuation of the at least one another pair of rollers being carried out from the other side by the second actuating element.
