Patent ID: 8453958

Claim:
A method of record winding a multi-layer film comprising a cover tape for a carrier tape, the cover tape comprising a resin film layer and a seal layer, to a winding core, the method comprising steps of: record winding a multi-layer film onto a winding core; and increasing a winding tension Y x on the multi-layer film in accordance with a length of the multi-layer film wound on a winding core by 0.10% per meter wound or less, relative to a value of the tension at a start of the winding, according to the equation: Y x =Y 0 (1 +aX/ 100), where Y 0 is the value of the winding tension at the start of winding where the length of tape wound onto the winding core is zero, a is the rate of change of the tension in % per meter wound, and Y x is the value of the winding tension at the time when the length, in meters, of the multi-layer film wound on the winding core is X.
