Wet spinning machine and carbon fiber manufacturing equipment with a guide roll unit and the guide roll unit of the fiber tows

摘要

PROBLEM TO BE SOLVED: To provide: a guide roll unit for a precursor fiber bundle giving a high-quality product and excellent in productivity, which leads to no increase in installation space, requires no time for exchanging work, prevents an increase in equipment cost, and can smoothly and stably guide even various types of the precursor fiber bundles having different volumes or the like; a wet spinning machine having the same; and a carbon fiber manufacturing apparatus having the same.;SOLUTION: A guide roll unit (10) for guiding a plurality ot fiber tows (3) in a parallel manner through a grooved guide roll (11) for guiding the running fiber tow (3) composed of a number of filaments, comprises: an shaft part (13) having both ends in its axial direction rotatably supported through a bearing (12); at least one pair of brackets (14) provided in both ends of the shaft part so as to be extended from the shaft part; and a grooved guide roll (11) supported between the brackets, in which the shaft part is provided with two or more sets of the pair of brackets (14).;COPYRIGHT: (C)2012,JPO&INPIT
