PROBLEM TO BE SOLVED: To inexpensively provide a roller head extruder of a small space capable of performing the removal of a residual rubber or maintenance without moving the extruder. SOLUTION: In the roller head extruder 1 equipped with a pair of upper and lower rollers 6 and 7 for holding a rubber material to mold a rubber sheet and an extruder 10 constituted so that the rubber material is fed under pressure by an extrusion pressure feed part 11 to be introduced in an extrusion head 12 under pressure and discharged to the gap between the upper and lower rollers 6 and 7 by the extrusion head 12, the extrusion pressure feed part 11 is arranged so as to be directed in parallel to the axis of the rollers 6 and 7, and a flow channel bending the flow of the rubber material, which is introduced into the extrusion head 12 in parallel to the axis of the upper and lower rollers 6 and 7 by the extrusion pressure feed part 11, at an almost right-angled direction to discharge the same to the gap between the rollers 6 and 7 is formed to the extrusion head 12 and so divided that the rear surface side opposite to the side discharging the rubber material to the upper and lower rollers 6 and 7 is made openable.
