Abstract
Official abstract text for this publication.
An apparatus for manufacturing a belt-like electrode including: a pair of press rolls configured to press a belt-like current collector foil with an electrode mixture layer along a longitudinal direction in a thickness direction of the electrode mixture layer; and a stretching roll configured to stretch a non-forming part which is the current collector foil without the electrode mixture layer in respective ends in a width direction is provided. The stretching roll includes: a first roll opposed to the electrode mixture layer formed in the current collector foil; and a pair of second rolls arranged in respective ends of the first roll in an axial direction and opposed to the non-forming part, and a central axis of the first roll is deviated with respect to a central axis of the pair of second rolls in a direction away from the stretched current collector foil.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus for manufacturing an electrode belt comprising: a pair of press rolls configured to press a belt-shaped current collector foil in which an electrode mixture layer is formed along a longitudinal direction in a thickness direction of the electrode mixture layer; and a stretching roll configured to stretch a non-forming part in which the electrode mixture layer is not formed and the current collector foil is exposed in respective ends of the current collector foil in a width direction, wherein the stretching roll comprises: a first roll that is opposed to the electrode mixture layer formed in the current collector foil; and a pair of second rolls arranged in respective ends of the first roll in an axial direction, the pair of second rolls being opposed to the non-forming part, and a central axis of the first roll is deviated with respect to a central axis of the pair of second rolls in a direction away from the current collector foil that is stretched. 2. The apparatus for manufacturing the electrode belt according to claim 1 , wherein the stretching roll further comprises: a first shaft that forms a rotation axis of the first roll; and a pair of second shafts that form the rotation axis of the pair of second rolls, and at least one of the pair of second shafts has a cylindrical shape and the first shaft is inserted into the one of the pair of second shafts. 3. The apparatus for manufacturing the electrode belt according to claim 1 , wherein the first roll has a hollow structure.
