A roller head extruder unit includes an extruder unit, a pair of calender rollers arranged forward of an exit opening of the extruder unit and supported for rotation by a support frame mounted securely with respect to the extruder unit, and side guides arranged on either side of a space between the exit opening of the extruder unit and the calender rollers to thereby define a bank into which material for rolling is extruded. At least one of the upper and lower rollers is mounted for rotation in a roller housing supported by the support frame for limited movement in a direction perpendicular to the axis of the upper and lower rollers. The roller head extruder unit also includes a detection device for detecting the force with which this roller housing is caused to move as a result of accumulation of material in the bank.
