Washing apparatus, apparatus for manufacturing plating-filmed web, washing process, and process for manufacturing plating-filmed web

A washing apparatus which washes a web while conveying the web, the washing apparatus comprising:

• a squirting component which ejects fresh washing liquid at the web;
• and
• a first washing tank which is disposed at an upstream side of a conveyance direction of the web relative to the squirting component, washes the web that is passing through the first washing tank, and takes in the washing liquid that has been ejected at the web by the squirting component,
• a pair of liquid-extracting rollers which nip the web at the web conveyance direction downstream side relative to the squirting component,
• wherein a portion of the squirting component ejects teh washing liquid at the liquid-extracting rollers.

A production facility for manufacturing a plating-filmed web, the production facility, while conveying a web which includes a conductive surface, causing the conductive surface of the web to contact a cathode roller and forming a plating coat at the conductive surface of the web in an electroplating solution, and the production facility comprising:

• a washing apparatus at a downstream side of a conveyance direction of the web relative to the electroplating solution, the washing apparatus washing off plating liquid that has adhered to the web,
• wherein the washing apparatus includes:
• a squirting component which ejects fresh washing liquid at the web;
• and
• a first washing tank which is disposed at the web conveyance direction upstream side relative to the squirting component, washes the web that is passing through the first washing tank, and takes in the washing liquid that has been ejected at the web by the squirting component,
• a pair of liquid-extracting rollers which nip the web at the web conveyance direction downstream side relative to the squirting component,
• wherein a portion of the squirting component ejects the washing liquid at the liquid-extracting rollers.

A washing method for washing a web while conveying the web, the method comprising:

• (a) ejecting fresh washing liquid at the web by a squirting component;
• (b) prior to (a), passing the web through a first washing tank, which takes in the washing liquid that has been ejected at the web;
• (c) nipping the web at the web conveyance direction downstream relative to the squirting component by a pair of liquid-extracting rollers;
• and
• (d) ejecting the washing liquid at the liquid-extracting rollers by a portion of the squirting component.

A method for manufacturing a plating-filmed web, the manufacturing process including, while conveying a web which includes a conductive surface, causing the conductive surface of the web to contact a cathode roller and forming a plating coat at the conductive surface of the web in an electroplating solution, and the manufacturing method comprising

• after conveying the web through the electroplating solution, washing off plating liquid that has adhered to the web with a washing method,
• wherein the washing method includes:
• (a) ejecting fresh washing liquid at the web by a squirting component;
• (b) prior to (a), passing the web through a first washing tank, which takes in the washing liquid that has been ejected at the web;
• (c) nipping the web at the web conveyance direction downstream side relative to the squirting component by a pair of liquid-extracting rollers;
• and
• (d) ejecting the washing liquid at the liquid-extracting rollers by a portion of the squirting component.
