Abstract:
Provided is a method for producing a separator which method less causes a tear in the separator. The method is a method for producing a separator by slitting, in a direction in which a separator original sheet ( 12 b ) being porous is conveyed, the separator original sheet ( 12 b ) into a plurality of separators ( 12 a ), including the steps of: (a) conveying the separator original sheet ( 12 b ) in a state where the separator original sheet ( 12 b ) is in contact with a roller ( 77 ); and (b) slitting the separator original sheet ( 12 b ) at a portion where the separator original sheet ( 12 b ) is in contact with the roller ( 77 ).

Claim (Index 9):
A method for slitting, in a direction in which a separator original sheet being porous is conveyed, the separator original sheet into a plurality of separators each for use in a lithium-ion secondary battery, comprising the steps of:\n (a) conveying the separator original sheet in a state where the separator original sheet is in contact with a roller; and (b) slitting the separator original sheet at a portion where the separator original sheet is in contact with the roller, in the step (b), the separator original sheet being slit at a position that is located on an end position side of a middle position on a circumferential surface of the roller which middle position corresponds to a midpoint of a straight line via which a start position, at which the separator original sheet starts to be wound on the roller, and an end position, at which winding of the plurality of separators on the roll ends, are connected to each other and that is located on an upstream side of the end position.
