Method of manufacturing cord included rubber sheet

A method for manufacturing a cord included rubber sheet comprising:

• an arrangement step of supplying a band-like material of a cord included rubber sheet to a processing table, and arranging a portion to be cut in the band-like material onto a groove which is formed in the processing table;
• and
• a cutting step of cutting the band-like material by moving a pressure cutting die having an angle of a leading end which is larger than an opening angle of the groove and is equal to or greater than a 85 degrees, relatively closer to the processing table, and pressing the pressure cutting die in a thickness direction of the band-like material, and obtaining the cord included rubber sheet having a predetermined length,
• wherein a leading end of the pressure cutting die is caused to enter the groove and a die surface of the pressure cutting die is brought into contact with an opening edge of the groove, in the cutting step, and a cut surface of the cord is coated with the rubber of the band-like material in a process that the die surface comes into contact with the opening edge after the leading end of the pressure cutting die is in contact with the band-like material.
