## Abstract

There is provided an apparatus for folding a pouch for a secondary battery, the apparatus including: a forming means configured to gradually bend and fold an edge of a pouch-type secondary battery so that the edge has a target cross-sectional shape; a support means configured to support the forming means; and first to fourth gap spacers having various thicknesses, formed in a flat plate shape, and configured to be interposed between the forming means and the support means to align the forming means.

## Claims

### Claim 1

An apparatus for folding a pouch for a secondary battery, the apparatus comprising:
a forming means configured to gradually bend and fold an edge of a pouch-type secondary battery so that the edge has a target cross-sectional shape;
a support means configured to support the forming means; and
first to fourth gap spacers having various thicknesses, formed in a flat plate shape, and configured to be interposed between the forming means and the support means to align the forming means.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the support means includes:
a base plate horizontally extending in a direction in which the pouch-type secondary battery travels; and
a stand fixedly mounted on an upper surface of the base plate,
wherein the stand includes:
a support plate horizontally extending in a longitudinal direction of the base plate and fixedly mounted on the base plate; and
a mounting plate extending in a longitudinal direction of the support plate and vertically extending to an upper portion of the support plate, and
wherein one side of the mounting plate is sequentially divided into a first forming region, a second forming region, and a third forming region in the direction in which the pouch-type secondary battery travels.

### Claim 3 (depends on 2)

The apparatus of claim 2, wherein the forming means includes:
a first forming part supported in the first forming region and having roll formers each having a pair of upper and lower forming rolls configured to bend the edge of the pouch-type secondary battery so that the edge has an acute angle;
a second forming part supported in the second forming region and having roll formers each having a pair of upper and lower forming rolls configured to bend the edge of the pouch-type secondary battery unloaded from the first forming part so that the edge has an obtuse angle; and
a third forming part supported in the third forming region and having roll formers each having a pair of upper and lower forming rolls configured to bend the edge of the pouch-type secondary battery unloaded from the second forming part so that the edge is horizontal.

### Claim 4 (depends on 3)

The apparatus of claim 3, wherein the upper forming rolls and the lower forming rolls of the roll formers of the first forming part, the lower forming rolls of the roll formers of the second forming part, and the upper forming rolls and the lower forming rolls of the roll formers of the third forming part are rotatably mounted on the mounting plate, the upper forming rolls of the roll formers of the second forming part are rotatably mounted on a lower portion of a saddle horizontally extending in a longitudinal direction of the stand in the second forming region, a folding guide is mounted on one surface of the saddle, and the folding guide supports a non-bent portion and a bent portion of the edge when the edge is bent by the roll formers of the second forming part.

### Claim 5 (depends on 3)

The apparatus of claim 3, wherein the first gap spacer is vertically interposed between the mounting plate and the upper forming rolls and the lower forming rolls of the roll formers of the first forming part in the first forming region.

### Claim 6 (depends on 3)

The apparatus of claim 3, wherein the first gap spacer is vertically interposed between the mounting plate and the lower forming rolls of the roll formers of the second forming part in the second forming region.

### Claim 7 (depends on 3)

The apparatus of claim 3, wherein the first gap spacer is vertically interposed between the mounting plate and the upper forming rolls and the lower forming rolls of the roll formers of the third forming part in the third forming region.

### Claim 8 (depends on 4)

The apparatus of claim 4, wherein the second gap spacer is horizontally interposed between the support plate and a column extending vertically downward from the other surface of the saddle and fixed at the other side of the mounting plate.

### Claim 9 (depends on 4)

The apparatus of claim 4, wherein the third and fourth gap spacers are disposed in a mounting groove portion formed in one surface of the saddle on which the folding guide is mounted, the third gap spacer is horizontally interposed between an upper surface of the mounting groove portion and an upper surface of the folding guide, and the fourth gap spacer is vertically interposed between a lateral surface of the mounting groove portion and the other surface of the folding guide.
