## Abstract

A stacking device which stacks together web members which drop down while drawing a parabolic arc, this is provided with a horizontal movement limit part which limits movement of web members in a horizontal direction, a temporary supporting unit which can take a projecting position where it projects from the horizontal movement limit part and a retracted position where it is pulled in from the projecting position and does not stick out from the horizontal movement limit part, and a receiving table which is positioned under the temporary supporting means at the projecting position and stacks the web members. The temporary supporting unit temporarily supports a web member at the projecting position and, after that, shifts to the retracted position to make the web member drop under the temporary supporting unit, so that the stacking device stacks the web members on the receiving table.

## Claims

### Claim 1

A stacking device which stacks together web members which drop down while drawing a parabolic arc, which stacking device is provided with:
a horizontal movement limit part which limits movement of web members in a horizontal direction,
a temporary supporting means which can take a projecting position where it projects from said horizontal movement limit part and a retracted position where it is pulled in from said projecting position and does not stick out from said horizontal movement limit part, and
a receiving table which is positioned under said temporary supporting means at said projecting position and stacks said web members,
said temporary supporting means temporarily supporting said web member which is dropping off toward said temporarily supporting means when at said projecting position and, after that, shifting to said retracted position to make said web member drop under said temporary supporting means and thereby stack said web members on said receiving table.

### Claim 2 (depends on 1)

The stacking device as set forth in claim 1, wherein said temporary supporting means is inclined in a top direction from its base to its tip.

### Claim 3 (depends on 1)

The stacking device as set forth in claim 1, wherein said temporary supporting means is a plurality of rod-shaped members.

### Claim 4 (depends on 1)

The stacking device as set forth in claim 1, wherein said receiving table is a conveyor which conveys the stacked web members.

### Claim 5 (depends on 1)

The stacking device as set forth in claim 1, wherein
the device is further provided with a vertical direction aligning means which faces said horizontal movement limit part and is arranged at a height position where said web members are to be stacked, and
a distance between said horizontal movement limit part and said vertical direction aligning means is the same as the width of said web members or slightly greater than that distance.

### Claim 6 (depends on 1)

A method of producing a web member which includes a step of using a stacking device as set forth in claim 1 to stack said web members.
