  • Patent number: 4252010
    Abstract: An improved rectilinear draw machine, effective to directly draw ferrous and non-ferrous materials, is described, which is capable of automatic and continuous control and capable of adjusting the working speed without conveying the drawn material onto outer sensors. The machine comprises drawing sections, each section being formed by a drawing ring, an idle ring coaxial therewith and a compensating arm between the rings. These three elements rotate in the same direction. The lower drawing ring is driven by the driving shaft. A hollow central shaft is fixed to the upper idle ring, which is coaxial with the lower drawing ring, but of lesser diameter. The lower end of the hollow shaft is connected to the central body of an electromagnetic brake. The compensating or balancing arm, located between the lower drawing ring and the upper idle ring, is rigid with a shaft the lower end of which is connected to the inner body of the electromagnetic coupling or coupling.
