Abstract (en)
[origin: EP3706515A1] The purpose of the present invention is to manufacture a charge amount-controlled web without providing the web, such as an elongated polymer film, with an advance charge. Provided is a web manufacturing method comprising a transfer step of transferring a web, wherein a liquid is supplied to the interface of a transfer roll transferring the web and the web, and a charge amount on a surface of the web due to frictional charging between the transfer roll and the web is controlled. The liquid includes, for example, a liquid that produces, between the transfer roll and the web, a frictional charge of the opposite polarity from the charge polarity produced on the surface of the web due to frictional charge between the transfer roll and the web.
