Abstract:
1. An original fabric pitch feed mechanism of an original fabric manufacturing device for electrochemical elements, the original fabric pitch feed mechanism being provided on a downstream side of an insulating tape tension-attachment process region on a long original fabric that has electrodes formed on at least one surface thereof at predetermined intervals and in which an insulating tape is to be attached in a tensioned state to boundary portions between the electrodes and electrode non-formed portions, the original fabric pitch feed mechanism pitch-feeding the original fabric in one direction in accordance with the boundary portions, the original fabric pitch feed mechanism comprising: a feed side roller which is provided on an original fabric feed side and feeds the original fabric toward a take-up side while placing the original fabric thereon; an original fabric take-up side roller which is provided on the original fabric take-up side and receives the original fabric while placing the original fabric thereon; a feed side contacting/separating member which is adapted to move into contact with the feed side roller and presses the original fabric against the feed side roller when the original fabric is drawn from the original fabric take-up side of the feed side roller and move away from the feed side roller when the original fabric is fed to the feed side of the feed side roller; a take-up side contacting/separating member which is adapted to move into contact with the original fabric take-up side roller and presses the original fabric against the original fabric take-up side roller when the original fabric is fed to the feed side of the feed side roller and move away from the original fabric take-up side roller when the original fabric is drawn from the original fabric take up side of the original fabric take-up side roller; and a pitch feed roller which is disposed between the feed side roller and the original fabric take-up side roller and is adapted to move into and out of tension contact with the original fabric, and contacts the original fabric between the feed side roller and the original fabric take-up side roller, to draw the original fabric from the feed side of the feed side roller by a predetermined dimension when the feed side contacting/separating member moves away from the feed side roller and the take-up side contacting/separating member comes into contact with the original fabric take-up side roller to fix the original fabric in a sandwiching manner.
