Apparatus and method for folding sides of pouch-type battery and die for the same

Abstract

Disclosed are an apparatus and a method for folding sides of a pouch-type battery and a die for the same. The apparatus for folding sides of a pouch-type battery includes a die including a folding formation space including an inlet through which a side of a pouch-type battery enters, an outlet through which the side of the pouch-type battery exits, and a side opening formed on one side of the die to guide side of the pouch-type battery to pass therethrough, and a transfer unit that transfers the pouch-type battery along a longitudinal direction of the die. A space between the inlet and the outlet of the folding formation space is formed so that the side of the pouch-shaped battery having entered the inlet is gradually folded while moving and finally the outlet has a final folding shape.
