Abstract
Extrusion die systems, die changers and related methods are provided herein. The die changer for changing of dies in and out of an extrusion line can include a housing having a main supply feed bore therethrough for directing a flowable material and a channel oriented transversely to the main supply feed bore. The die changer can include a slide plate movable through the channel and transverse to a direction of flow through the bore. The slide plate can include an elongate body having a first section and a second section. A first bore can extend through the first section of the elongate body of the slide plate and a second bore can extend through the second section of the elongate body of the slide plate. The slide plate of the die changer can be moved within the channel of the housing between a first position where the first bore in the first section of the elongate body of the slide plate is aligned with the main supply feed bore and a second position where the second bore in the second section of the elongate body of the slide plate is aligned with the main supply feed bore.
