HIGH TEMPERATURE PROCESSING FURNACE AND REINFORCEMENT FIBER SUCCEEDING METHOD

摘要

PROBLEM TO BE SOLVED: To largely reduce hours required to succeeding operation of a reinforcement fiber F, and to satisfactorily improve productivity of high temperature processing of the reinforcement fiber F.SOLUTION: A first shutter 25 that opens and closes a first communication passage 23 to communicate an inside of a first bobbin chamber 11 with an inside of a furnace body 3 is disposed in a horizontal opening closing direction in which reciprocation can be performed at a midstream of an upper part communication sleeve 21, and a first shutter 25 that opens and closes the first communication passage 23 to communicates an inside of a first bobbin chamber 11 with an inside of the furnace body 3 is disposed in a horizontal opening closing direction in which reciprocation can be performed at a midstream of the upper part communication sleeve 21.
