摘要： A filter unit for an extruder system has an outer support body, which is hollow cylindrical and limits an interior. A plurality of outer through-openings open into the interior. An outer filter element is arranged on the support body in the region of the outer through-openings. An inner support body with a plurality of inner through-openings is arranged in the interior. An inner filter element is arranged on the inner support body in the region of the inner through-openings. Using the filter unit according to the invention, a low differential pressure of a plastics material melt to be filtered can be achieved as both the outer filter element and the inner filter element provide a corresponding filter area.

摘要： 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.
