７に送出する。 To explain the method of the present invention, which is carried out using such an apparatus, using the production of a synthetic resin fastener chain as an example, first, the fastener tape 5 is supplied between the fixed mold 1 and the movable mold 2, and then the fastener tape 5 is supplied between the fixed mold 1 and the movable mold 2. is brought into contact with the fixed mold 1 to form a molding cavity around the fastener tape 5. Next, the movable plate 25 is raised by the cylinder 26, the motor 23 is operated and rotated, and a desired hopper (for example, the second
In the figure, when 12) comes directly above the supply port 13 of the material supply section 3, it stops. Then, when the movable plate 25 is lowered by the action of the cylinder 26, the hopper 12
is also lowered, and the tip of the discharge pipe 32 is connected to the supply port 13.
It will fit inside and stop. This is to prevent the discharged material from spilling around the supply port 13. At this time, the protrusion at the end of the shutter 18 is caught by the claw at the tip of the rod 30 of the cylinder 29, so the cylinder 29 is actuated and the shutter 18
is pushed forward, the opening 31 communicates with the discharge pipe 32 at the bottom of the hopper, and the material supply section 3 is filled with the molding material in the hopper. Next, the supplied molding material is melted and pressurized, passes through the injection section 4, and is transferred to the fixed mold 1.
and the movable mold 2. The molded fastener chain 6 is sequentially delivered to a stocker 7.

It operates to raise the movable plate 25, and operates the motor 23 to rotate the rotating shaft 17. The sensing unit 28 is connected to the brush 1 in the wiping device 16.
4 is directly above the supply port 13, the motor 23 stops operating, and the cylinder 26
is operated in the downward direction to lower the movable plate 25. At this time, the cylinder 19 is operated to lower the brush while rotating. With this, the supply port 13
Scrape off the material accumulated on the inner wall, then raise the movable plate 25, slightly rotate the rotating shaft 17, stop when the felt 15 is located directly above the supply port 13, and move the movable plate 25 up. Go down and brush 1
4, due to the action of the cylinder 20,
The felt 15 is rotated and lowered. This completely wipes the inside of the supply port 13.
ついで、上記と同様の手順で、ホツパー８を供
