Title:
CONDUCTIVE BELT MANUFACTURING METHOD
Document Type and Number:
Japanese Patent JP2003080530
Kind Code:
A
Abstract:

To obtain a conductive belt free from irregularity in conductivity as a whole by preventing the generation of a gas entrapment in the conductive belt caused by air or gas generated at the time of vulcanization or the foaming of a rubber constituting the conductive belt.

An unvulcanized rubber tube 1 is molded by the extrusion molding of a rubber having conductivity and subsequently allowed to cover an inner mold 2 to be heated and pressurized between the inner mold 2 and an outer mold 4 to manufacture the conductive belt 7 made of the vulcanized rubber. Air permeability is provided between the molds 2 and 4 and the unvulcanized rubber tube 1 at the time of vulcanization.
