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

Abstract

Provided is a pitch feed mechanism which is capable of performing an accurate, high-speed pitch feed of an original fabric having unevenness on a surface thereof in a sticking operation of an insulating tape. () The original fabric pitch feed mechanism () that is provided on a downstream side of an insulating tape sticking process region (K) in a long original fabric (), and performs the pitch feeding of the original fabric () in one direction in accordance with a boundary part (H), the original fabric pitch feed mechanism () being characterized by comprising () a feed side roller (), () an original fabric take-up side roller (), () a feed side contact and separate member (), () a take-up side contact and separate member (), and () a pitch feed roller (), which is disposed between the feed side roller () and the original fabric take-up side roller (), and pulls out, when the feed side contact and separate member () is separated from the feed side roller (), and the take-up side contact and separate member () is in contact with the original fabric take-up side roller () to fix the original fabric () with the original fabric () disposed therebetween, the original fabric () by a predetermined size from the feed side roller () side by pressing the original fabric () that is extended between the feed side roller () and the original fabric take-up side roller ().
