Abstract

PURPOSE:To contrive not to stop all operations of an extruder when there occurs a cause to stop operations at the crosshead side, by arranging compound feed stopping valves and compound discharging channels between the crosshead and a cylinder. CONSTITUTION:The compound fed in the cylinder 1 is advanced by rotating a screw 2 through a compound feeding valve 8 to a screen 3 and a breaker plate 4 where foreign matters are discharged, and is delivered into the crosshead 5. If there occurs a cause to stop the operations at the side of the head 5 such as the need to replace a core bar or a cap, the stopping valve 8 is closed to shut off the head 5 from the cylinder 1, and at the same time the opening and closing valves 9, 9' of the compound discharging channels 10, 10' are opened to discharge the compound. Thus, if a trouble has abruptly occurred at the crosshead side, the feeding of the compund can be instantly discontinued.
