| titleOfInvention | Method of manufacturing charging roll |
| abstract | (57) An object of the present invention is to provide a charging roll in which an elastic foam layer made of at least a foaming material is integrally formed around a cylindrical cored bar, and the nip width between the charging target and the charging target is all over the axial direction. To make it possible to easily and inexpensively manufacture a charging roll that is uniform and can be charged satisfactorily without uneven charging. An elastic foam layer (3) of a cylindrical cored bar (2) After forming the layer forming portion (2a) in the axial direction so that the outer diameter on both end sides of the portion is larger than the outer diameter on the central side, the layer forming portion of the core metal is And extruding the foamable material (4) by an extrusion molding method so that the outer diameter of the entire layer forming portion becomes constant, and then the core metal extruded from the foamable material is pressed from the outer diameter of the entire layer forming portion. After being installed concentrically in a cylindrical mold accommodating portion (5a) having a large inner diameter, the foamable material was foamed by heating and then cooled to obtain the charging roll (1). |
