First, the cable 1, which is arranged and integrated by the clip 100, is attached to the lower mold 210, and the clip 100 is inserted into the clip mounting groove 211 of the lower mold 210. The cable 1 fixed to the clip 100 is naturally positioned in the cable insertion groove 212 and the operator inserts all the cables 1 into the cable insertion groove 212 by pressing the plurality of cables 1 at once. In this way, the cable 1, which has already been arranged and length-adjusted, can be simply inserted, which makes it possible to work very quickly and easily.

When the installation of the cable 1 is completed, the fixing plate 215 is rotated to cover the cable insertion groove 212 to prevent the cable 1 inserted into the cable insertion groove 212 from moving. Next, when the lower mold 210 on which the cable T is mounted rotates and the lower mold 210 is positioned below the upper mold 230, the upper mold 230 is lowered to supply the material to the cavity 213 and cool the same, The mat 2 is formed. When the table T rotates after the upper mold 230 is lifted and lowered, the lower mold 210 formed with the grommet 2 is located at the operator. When the ejector pin pushes up the molded grommet 2, the cavity 213 , The grommet 2 is released to complete the production of the grommet 2 in which the cable 1 is integrated. When the grommet 2 integrated with the cable 1 is removed from the lower mold 210, the new clip 100 and the cable 1 are mounted on the lower mold 210 and the process of covering the fixing plate 215 is repeated.

As shown in FIG. 11, the cable-integrated grommet 2 thus produced is produced in a state in which the clip 100 is mounted, and the cover 120 is detached from the fixing table 110 as shown in FIG. 12 The integrated cable grommet (2) is packed.
