Belt layer feeding frame and feeding method thereof

摘要

The present invention provides a belt layer feeding frame and a feeding method thereof wherein when a belt layer is transported to the front end of a transporting formwork a vertically adjusting apparatus applies a force to a frame of the transporting formwork making same swing upwards and making the frame of the transporting formwork rotate around a pin joint shaft of a machine frame until the top surface of the transporting formwork reaches a position tangential to the outer periphery of a belt layer drum. By using the feeding frame of the present invention when the belt layer and the belt layer drum are built up no matter how the size of the drum changes the two are in a tangential position throughout ensuring that the building up of the two is excellent thereby improving the shaping quality of the tyre.
