摘要

A web pressure welding method for pressure welding, with respect to a running web, a first belt-shaped annular body which contact surface rotates with running of at least one web, where an area pressure for pressure welding to the web side is applied on the contact surface of the first belt-shaped annular body.

主权项

1. A power supply method used in a continuous electrolytic plating apparatus for manufacturing a web with a plated coating film by performing electrolyte plating in a plating processing tank while continuously running a web applied with a conductive thin film on a surface, the method comprising the steps of:
pressure welding a first belt-shaped annular body to the web, the first belt-shaped annular body having a contact surface rotating with the web, wherein an area pressure for pressure welding to the web side is applied with respect to the contact surface of the first belt-shaped annular body; and supplying power to a conductive surface of the web through the first belt shaped annular body using a body which contact surface with the web has conductivity and is electrically connected to a plating power supply as the first belt-shaped annular body.
