FIELD: technological processes; transportation.
SUBSTANCE: invention relates to the field of rewinding equipment. Winding spindle attachment and supporting device is used in the machine for the polymer film winding into rolls. Winding machine comprises winding drum. Drum is located between two vertical posts. First post supports the rotating plate. On the plate, three spindles and central shaft are overhanging supported. Central shaft is a part of the winding drum. At the other end central shaft is supported by the second vertical post. Star-shaped plate with three support arms interacts with the three spindles free ends by means of the crank arm mechanism. Crank arm is actuated by the lever mounted actuator. Lever is pivotally connected to the star-shaped plate and is configured to rotate between the operating position and neutral position by the second actuator. In the operating position the corresponding spindle is locked. In the neutral position, the corresponding spindle is released. Increase in the spindle fastening reliability.
EFFECT: enabling possibility of the small diameter and weight rolls production at high speeds.
