Abstract

Provided are an electrolytic cathode structure that can suppress the degradation of an activated cathode even if a reverse current flows upon the stoppage of operation of an electrolyzer in an electrode structure allowing the distance between the electrode and an electrode current collector to be maintained at an approximately constant value, and an electrolyzer using the same.
The electrolytic cathode structure includes a metal elastic cushion member 1 compressed and accommodated between an activated cathode 2 and a cathode current collector 3 . At least a surface layer of the cathode current collector 3 consumes a larger oxidation current per unit area than the activated cathode. The electrolyzer is partitioned by an ion exchange membrane into an anode chamber for accommodating an anode and a cathode chamber for accommodating a cathode. The electrolytic cathode structure is used for the cathode.

First claim

The invention claimed is:

1. A method for manufacturing toilet roll products applied with chemicals comprising:
continuously manufacturing a secondary paper roll for the toilet roll products from a plurality of primary paper rolls using a ply machine, wherein said plurality of primary paper rolls have been manufactured and wound by a paper manufacturing machine,
wherein the ply machine includes
a multi-ply forming unit, which performs multi-ply forming on single-continuous sheets reeled out from said plurality of primary paper rolls so as to form a multi-ply continuous sheet,
a chemicals applying unit, which applies chemicals comprising at least one polyol to the multi-ply continuous sheet after it leaves the multi-ply forming unit, and
a winding unit, which winds the multi-ply continuous sheet applied with the chemicals so as to form the secondary paper roll, said secondary paper roll having a width plural times or more than a width of a toilet roll;

conveying the secondary paper roll for the toilet roll products to a winder and setting it in a paper roll support portion of said winder, wherein the chemicals spread and are absorbed by the multi-ply continuous sheet while it is being conveyed to and set in the paper roll support portion of the winder causing stretching of the multi-ply continuous sheet resulting from a stretching of its crepe; reeling out the multi-ply-sheet from the secondary paper roll that has been applied with the chemicals; forming perforation lines on the multi-ply continuous sheet reeled out from the secondary paper roll in the width direction of the multi-ply continuous sheet from the secondary paper roll at a predetermined interval; and after that, rewinding the multi-ply continuous sheet to a winding diameter of the toilet roll, so as to manufacture a log for the toilet roll;
conveying the log manufactured in the winder to a log cutter and cutting the log into the width of the toilet roll using a log cutter so as to provide individual toilet rolls; and
putting one or more of said individual toilet rolls in a product package so as to obtain the toilet roll products.

2. The method for manufacturing the toilet roll products applied with the chemicals according to claim 1 ,
wherein the ply machine includes an embossing unit, and the embossing unit performs single embossing on the multi-ply continuous sheet after or before application of the chemicals, where the single embossed multi-ply continuous sheet is not separated into its single sheets before forming the toilet roll products.

3. The method for manufacturing the toilet roll products applied with the chemicals according to claim 1 ,
wherein the ply machine includes an embossing unit which is provided before the multi-ply forming unit, embosses the single continuous sheets from one or more of said plurality of the primary paper rolls, and after that, the multi-ply forming unit performs multi-ply forming on the embossed single continuous sheets from the plurality of primary paper rolls.

4. The method for manufacturing the toilet roll products applied with the chemicals according to claim 1 ,
wherein the ply machine includes the multi-ply forming unit, a ply-separating unit, an embossing unit, and a re-multi-ply forming unit arranged in this order, and
wherein the multi-ply forming unit performs multi-ply forming on single continuous sheets reeled out from said plurality of primary paper rolls to form the multi-ply continuous sheet, and the ply-separating unit then ply-separates the multi-ply continuous sheet into its constituent single continuous sheets, and at least one of which is then embossed by the embossing unit.

5. The method for manufacturing the toilet roll products applied with the chemicals according to claim 1 ,
wherein the winder includes an embossing unit, and the embossing unit performs single embossing on the multi-ply continuous sheet from the secondary paper roll, which has been reeled out from the secondary paper roll and applied with the chemicals, and where the single embossed multi-ply continuous sheet is not separated into its single sheets before forming the toilet roll products.

6. The method for manufacturing the toilet roll products applied with the chemicals according to claim 1 ,
wherein the ply machine includes a slitting unit positioned between the chemicals applying unit and the winding unit, and
wherein the slitting unit slits the multi-ply continuous sheet reeled out from the secondary paper roll applied with the chemicals into the width plural times or more than the width of the toilet roll and after that, the winding unit winds the multi-ply continuous sheets, which have been cut into the width plural times or more than the width of the toilet roll.

7. The method for manufacturing the toilet roll products applied with the chemicals according to claim 1 ,
wherein the ply machine includes a ply bonding unit, which is provided after the multi-ply forming unit, and performs linear ply bonding on the multi-ply continuous sheet so as to prevent ply-separating, and
the ply bonding unit performs ply bonding at intervals that correspond to the width of the toilet roll.

8. The method for manufacturing the toilet roll products applied with chemicals according to claim 1 ,
wherein the winder includes an embossing unit, which is positioned before the perforation line applying unit, and performs single embossing on the multi-ply continuous sheet applied with the chemicals and reeled out from the secondary paper roll.

9. The method for manufacturing toilet roll products applied with chemicals according to claim 1 ,
wherein the winder includes a ply-separating unit, an embossing unit, and a re-multi-ply forming unit, which are positioned in this order and before the perforation line applying unit, and
wherein the ply-separating unit ply-separates the multi-ply continuous sheet applied with the chemicals reeled out from the secondary paper roll, into its constituent single continuous sheets, the embossing unit then embosses one or more of the ply-separated single continuous sheets, and then the re-multi-ply forming unit performs re-multi-ply forming on the single continuous sheets to produce a second multi-ply continuous sheet.

10. The method for manufacturing the toilet roll products applied with the chemicals according to claim 4 ,
wherein the ply machine includes a ply bonding unit which is positioned after the re-multi-ply forming unit and performs linear ply bonding on the multi-ply continuous sheet so as to prevent ply-separating, and
the ply bonding unit performs ply bonding at intervals corresponding to the width of the toilet roll.

11. A method for manufacturing toilet roll products applied with chemicals, comprising:
continuously manufacturing a secondary paper roll for the toilet roll products from a primary paper roll using a ply machine, wherein said primary paper roll has been manufactured and wound by a paper manufacturing machine,
wherein, the ply machine receives a single-ply continuous sheet having a width plural times or more than a width of a toilet roll from said primary paper roll and comprises:
a chemicals applying unit, which applies chemicals including at least one polyol to the single-ply continuous sheet after it leaves the multi-ply forming unit, and
a winding unit, which winds the single-ply continuous sheet applied with the chemicals;

wherein in the ply machine, one primary paper roll is used to form the single-ply continuous sheet, the chemicals are applied to the single-ply continuous sheet reeled out from said one primary paper roll, and the single-ply continuous sheet is then wound so as to manufacture the secondary paper roll comprising
