Apparatus and method for manufacturing resin-impregnated cured sheet, and apparatus and method for manufacturing carbonaceous material sheet

Abstract

An object of the present invention is to provide an apparatus and a method for manufacturing a windable carbonaceous material sheet, which is obtained by continuously curing a long uncured fiber sheet which is obtained by using short fibers to make paper and which contains uncured resin to produce a resin-impregnated cured sheet, and then continuously carbonizing it, and its production process. For the object, a long uncured fiber sheet ( 1 a ) is conveyed by conveyance means which is equipped with one rotation belt set ( 2 ) comprising a drive roll ( 2 a ), a follower roll ( 2 b ), and an endless belt ( 2 c ) which is put on and around these rolls ( 2 a , 2 b ). A resin-impregnated cured sheet ( 1 b ) is produced by heating and pressurizing the uncured fiber sheet ( 1 a ) by resin curing means ( 3 ) which is arranged so as to nip the uncured fiber sheet through the endless belt ( 2 c ). Further, the resin-impregnated cured sheet is continuously conveyed in a horizontal direction, and then is carbonized by the apparatus for manufacturing a carbonaceous material sheet which is equipped with a carbonization treatment chamber for carbonizing a carbonizing material and guide rolls which are provided in the carbonization treatment chamber, so that a carbonaceous material sheet is continuously produced. Then, this is wound up. Accordingly, production efficiency is remarkably improved, and its handling property and conveying property are excellent.
