Original fabric pitch feed mechanism of original fabric manufacturing device for electrochemical element

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 comes into contact with and moves away from the feed side roller and presses the original fabric against the feed side roller during contact;
• a take-up side contacting/separating member which operates in a manner opposite to that of the feed side contacting/separating member to come into contact with and move away from the original fabric take-up side roller and presses the original fabric against the original fabric take-up side roller during contact;
• and
• a pitch feed roller which is disposed between the feed side roller and the original fabric take-up side roller and presses the original fabric provided in a tensioned state between the feed side roller and the original fabric take-up side roller, to draw the original fabric from the feed side roller side 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.
