Pouch forming apparatus and method

A pouch forming apparatus comprising:

• a die defining forming grooves with a partition wall therebetween along a first surface;
• and
• a plurality of punch members, each of the plurality of punch members including a punch configured to be inserted into each of the forming grooves to press a pouch film to form a pair of accommodation grooves in the pouch film,
• wherein each of the forming grooves comprises a vertical space disposed above a forming groove bottom part and adjacent to the partition wall, and an inclined space connected to the vertical space, the inclined space defined by an inner wall defining an inclined surface facing the partition wall,
• the punch comprises a vertical block configured to be inserted into the vertical space to press the pouch film, and the punch further comprises an inclined block configured to be inserted into the inclined space to press the pouch film, wherein a surface of the inclined block, which faces the inner wall, is provided as an inclined surface, and wherein the punch comprises a coupling means configured to detachably couple the inclined block to the vertical block, and
• wherein an inner surface of each of the pair of the accommodation grooves, which is disposed between the inclined surface of the inclined space and the inclined surface of the inclined block, is formed into an accommodation groove inclined surface,
• wherein the coupling means comprises a coupling groove formed in the vertical block and a coupling protrusion formed on the inclined block and configured to be coupled to the coupling groove.
