APPARATUS FOR FOLDING POUCH

A device for folding a pouch which has a first cup part and a second cup part, each having a concavely recessed shape to accommodate an electrode assembly, and in which a first circumferential part is formed flat along a circumference of the first cup part, and a second circumferential part is formed flat along a circumference of the second cup part, includes: a lower nest on which the first cup part is seated; an upper nest on which the second cup part is seated; a guide provided with a first guide fixed to the lower nest and having a first protrusion protruding upwardly therefrom, and a second guide fixed to the upper nest and having a second protrusion protruding upwardly therefrom, the first protrusion and the second protrusion which protrude from the first guide and the second guide being in close contact with each other to form a support protrusion; and a pressing part that allows a connection part of the first circumferential part and the second circumferential part to be in close contact with the support protrusion when the first cup part and the second cup part are seated on the lower nest and the upper nest, respectively, wherein in a state where the pressing part allows the connection part to be in close contact with the support protrusion, the upper nest rotates so that the second cup part is folded onto the first cup part.
