1. An insulation sheet forming apparatus, which forms an insulation sheet having one or more bent regions, the insulation sheet forming apparatus comprising:
an unwinding module configured to unwind and supply the insulation sheet;
a preforming module configured to form a preforming region on the insulation sheet by pressing a partial region of the insulation sheet to form the one or more bent regions on the insulation sheet supplied from the unwinding module; and
a bending module configured to form the one or more bent regions on the insulation sheet by bending the insulation sheet around the preforming region formed on the insulation sheet supplied from the preforming module,
wherein the preforming module includes:
an upper preforming portion disposed at an upper side of the preforming module; and
a lower preforming portion disposed below the upper preforming portion, and
wherein the preforming module has a width which is adjustable in a width direction that intersects a movement direction of the insulation sheet,
wherein the bending module includes a first bending portion, and
wherein the first bending portion includes first guide members disposed at two opposite sides in the width direction of the insulation sheet and configured to guide two opposite ends in the width direction of the insulation sheet inward in the width direction and move external regions of the insulation sheet inward in the width direction based on preforming regions.
