Vacuum processing device

1. A device of executing vacuum processing on a reinforcement fiber, comprising:

a chamber capable of keeping the chamber as a whole in a depressurized state;

a feeding roller so disposed as to hang the reinforcement fiber down in the chamber;

a processor so disposed in the chamber as to pass the reinforcement fiber hung down in the chamber through the processor;

a capture device so disposed as to capture and keep a leading end of the reinforcement fiber passing the processor and vertically falling down in place;

a winding bobbin configured to wind the reinforcement fiber processed by the processor; and

a resilient cord withdrawn in synchronism with the winding bobbin from a first position where the resilient cord surrounds the leading end kept in place by the capture device to a second position where the resilient cord gets in contact with and leads the reinforcement fiber to the winding bobbin.

2. The device of claim 1 , wherein the chamber comprises a first sub-chamber housing the feeding roller, a main chamber housing the processor, and a second sub-chamber housing the capture device, the winding bobbin and the resilient cord, and the main chamber is configured to temporarily get gas-tightly separated from the first sub-chamber and the second sub-chamber.

3. The device of claim 1 , wherein a proximal end of the resilient cord is so combined with the winding bobbin as to be withdrawn by rotation of the winding bobbin.

4. The device of claim 3 , wherein a distal end of the resilient cord is fixed to a site other than the resilient cord and the resilient cord in the first position forms an open loop surrounding the reinforcement fiber.

5. The device of claim 4 , wherein the distal end of the resilient cord is combined with the winding bobbin.

6. A method of executing vacuum processing on a reinforcement fiber, comprising:

keeping a chamber as a whole in a depressurized state;

hanging the reinforcement fiber from a feeding roller down in the chamber;

passing the reinforcement fiber through a processor disposed in the chamber;

disposing a capture device so as to capture and keep a leading end of the reinforcement fiber passing the processor and vertically falling down in place;

disposing a resilient cord at a first position where the resilient cord encloses the leading end kept in place by the capture device above or around the capture device;

withdrawing the resilient cord in synchronism with a winding bobbin to a second position where the resilient cord gets in contact with and leads the reinforcement fiber to the winding bobbin; and

making the winding bobbin wind the reinforcement fiber processed by the processor.

7. The method of claim 6 , further comprising:

combining a proximal end of the resilient cord with the winding bobbin, wherein the resilient cord is withdrawn by rotation of the winding bobbin in the step of withdrawing the resilient cord.

8. The method of claim 7 , further comprising:

fixing a distal end of the resilient cord to a site other than the resilient cord so as to have the resilient cord in the first position form an open loop surrounding the reinforcement fiber.

9. The method of claim 8 , further comprising:

combining the distal end of the resilient cord with the winding bobbin.
