Generally, a fabric including a towel or the like needs to be folded in a certain form for packaging, shipping, and transportation.

In this case, when the work of folding the fabric into a certain shape is manually performed by the operator, it takes a lot of time, requires a lot of manpower, and the folding shape is not uniform.

Thus, fabric folding devices have been developed that fold and unload fabrics in an automated manner so that the fabrics can be quickly and accurately folded in a uniform fashion.

However, the above-mentioned conventional cloth folding devices have a structure in which the fabric is folded one or more times in the longitudinal direction and folded at least once in the width direction, while the fabric is conveyed in a long direction all the way through the conveyor.

That is, in order to fold the fabric folded in the longitudinal direction more than twice in the width direction, the blade must be operated at least twice in order to fold the fabric in the width direction while conveying the fabric along the conveyor, so that the length of the conveyor must be sufficiently long, And the space occupied by the apparatus is also increased.

In addition, since at least two blades for folding in the width direction are required to be formed, the structure is complicated and the control is not easy. In addition, since the conveyor is so long and the blades for folding in the width direction must operate with a parallax, there is a problem that the fabric folding time is also increased.
