  • Patent number: 10443122
    Abstract: A device of executing vacuum processing has a chamber capable of keeping the chamber as a whole in a depressurized state; a feeding roller so disposed as to hang a 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in place; a winding bobbin configured to wind the reinforcement fiber processed by the processor; and a resilient cord withdrawn in synchronism with the winding bobbin from a first position where the resilient cord surrounds the leading end kept in place by the capture device to a second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.

  • Patent number: 10006119
    Abstract: Arranged in the middle of an upper communication sleeve 21 is a first shutter 25 that is moved back and forth in a horizontal open-close direction to open and close a first communication path 23 that makes the inside of a first bobbin chamber 11 and the inside of a furnace body 3 communicate with each other. Arranged in a middle of a lower communication sleeve 53 is a second shutter 57 that is moved back and forth in a horizontal open-close direction to open and close a second communication path 55 that makes a second bobbin chamber 33 and the inside of the furnace body 3 communicate with each other.
