Abstract
Official abstract text for this publication.
To solve the above problem, a pouch forming apparatus according to an embodiment of the present invention includes: a die in which a forming space is recessed inward from a top surface thereof; a partition wall partitioning the forming space into first and second forming spaces; a stripper disposed above the die and configured to descend to contact the die with the pouch film therebetween to fix the pouch film to be seated on a top surface of the die; and an electromagnetic force generation part disposed above the forming space and configured to generate electromagnetic force and configured to apply the electromagnetic force to the forming space.
First claim
Opening claim text (preview).
The invention claimed is: 1. A pouch forming apparatus comprising: a die in which a forming space is recessed inward from a top surface thereof; a partition wall partitioning the forming space into first and second forming spaces; a stripper disposed above the die and configured to descend to contact the die with the pouch film therebetween to fix the pouch film to be seated on a top surface of the die; and an electromagnetic force generation part disposed above the forming space and configured to generate an electromagnetic force and configured to apply the electromagnetic force to the forming space, wherein the stripper is configured to contact only a peripheral portion of the die located outside of a periphery of the forming space with the pouch film therebetween without contacting the partition wall to fix the pouch film to be seated on the top surface of the die, and wherein the electromagnetic force generation part has a width in a horizontal direction parallel to the top surface of the die that is not greater than a respective width of each of the first forming space and the second forming space in the horizontal direction. 2. The pouch forming apparatus of claim 1 , wherein the electromagnetic force generation part is configured to be disposed above the first forming space. 3. The pouch forming apparatus of claim 2 , wherein the electromagnetic force generation part is configured to apply the electromagnetic force to the first forming space and then is configured to move to a location above the second forming space. 4. The pouch forming apparatus of claim 2 , wherein the electromagnetic force generation part is configured to be disposed above the second forming space. 5. The pouch forming apparatus of claim 1 , wherein the partition wall has a thickness of 0.1 mm to 3 mm. 6. The pouch forming apparatus of claim 5 , wherein the partition wall has a thickness of 1 mm to 2 mm. 7. The pouch forming apparatus of claim 1 , wherein an upwardly-protruding end of the partition wall has a curved surface.
