PROBLEM TO BE SOLVED: To process continuously materials of different kind without generating burn marks and uneveness of physical properties of a following material by generating no running-out of sheets at the time of changeover of a material and connecting a foregoing material with the following material without leaving the foregoing material remaining unconnected. SOLUTION: In an extruder, a roller die 2 consisting of two rollers 9, upper and lower, in paralleleach other is disposed on the front of an outlet of an extruder main body 1 with a rotatable screw 3 for extruding a material, and a storage section 12 encircled by side guides blocking both of left and right sides of the upper and lower rollers 9 and an outlet 7, is formed. When a foreging material to be extruded in the storage section 12 reaches the minimum bank amount to be connected with a following different material to be extruded, the roller die 2 is stopped, and the roller die 2 is started again when the following material to be extruded is restored to the given bank amount in the storage section 12. |
