Abstract
A screw extruder comprises a casing connected to a bed, the casing comprising two portions connected together longitudinally by connecting elements. At least one of the casing portions is articulated with respect to the bed, and the connecting elements are adapted to release the connection between the casing portions at a predetermined casing pressure to allow the casing portion to articulate to thereby open the casing.
