ABSTRACT:
To prevent an extruding material from moving in and between an extruder body and a contact surface of side guides and to provide automation of adjustment of a sheet width. A roller head extruder in which a pair of calendar rolls 8 are disposed forwardly of a material extruding opening 4 of an extruder body 1, a pair of left and right side guides 9 are disposed so that a material extruded from said extruding opening 4 is molded into a sheet form by the calendar rolls 8, wherein said side guides 9 can be automatically moved in a direction of the sheet width by a moving cylinder 19 and secured to the front surface of a flange portion 5 of the extruder body 1 by a fastening force releasable fastening means. The fastening force is added by a spring 15 and the fastening force is released by a jack 18. The fastening force urges the side guides 9 against the extruder body 1 so that no extruding material flows between the side guides 9 and the extruder body 1.
