PROBLEM TO BE SOLVED: To provide a method where, in an injection molding device of feeding ribbon rubber as the material, even if a rubber material melted from the inside of a heating tube is overflown, it is pulled into the heating tube as it is and is not dropped to the outside, thus the loss of operation time is reduced, a yield is made good, material cost is reduced and the steep rise of product cost is suppressed.SOLUTION: Provided is an injection molding device 1 where a continuous planar material 100 having a long-length planar shape in the plane view and also a rectangular shape in the front face view is guided to the material feed port 6 of the heating tube 4 of an injection molding device 1 formed almost into a rectangular shape in the front face view with almost the same shape of the front face view shape of the planar material 100, including a material posture changing device 61 of guiding the planar material 100 so as to change the posture almost by 90 degrees to the material feed port 6 and to be orthogonal toward the material feed prot 6. |
