PROBLEM TO BE SOLVED: To provide a feed method for a rubber sheet-like material in which the end of the rubber sheet-like material fed into a feed hopper of an extruder is cut into the shape to be inserted into an introduction opening of the feed hopper and fed automatically. SOLUTION: A publicly known foreign matter sensing device 13 is set in the width direction at the given inclination angle to the longitudinal direction of a carrying conveyor 1 in the middle of the carrying conveyor 1, and the foreign matter sensing device 13 is used for sensing foreign matters such as metal pieces and the like mixed into a rubber sheet-like material W carried by a conveyor belt 12. A movement distance sensor 14 for measuring the movement direction of the rubber sheet-like material W for pulse counting of the movement speed of the conveyor belt 12 is set in the middle of the conveyor belt 12, and the operation of the movement distance sensor 14 is carried out from signals from the foreign matter sensing device 13.
