Vacuum processing device

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

• a chamber including a single main chamber executing the vacuum processing and being capable of keeping the chamber as a whole in a depressurized state;
• a feeding roller so disposed as to hang down the reinforcement fiber in the main chamber;
• a winding bobbin winding the reinforcement fiber, the winding bobbin disposed in the chamber horizontally apart from the reinforcement fiber vertically hung down;
• a swing body pivotally supported in the chamber to swing about a pivot and including a suspension arm capable of capturing and suspending the reinforcement fiber according to a swing motion of the swing body, the suspension arm being capable of swinging from a first position horizontally apart from the reinforcement fiber vertically hung down, via a second position for capturing the reinforcement fiber, to a third position to suspend the reinforcement fiber above the winding bobbin;
• and
• a guiding pulley configured to cooperate with the feeding roller to put the reinforcement fiber in place,
• wherein the swing body includes an auxiliary arm to follow the suspension arm to swing and the auxiliary arm is so disposed as to capture the reinforcement fiber according to a swinging motion in advance of capturing the reinforcement fiber by the suspension arm and guide the reinforcement fiber to the suspension arm and the guiding pulley.
