していた。2. Description of the Related Art Conventionally, it has been extremely difficult to continuously separate and wind up narrow multi-row patterned products from thin, wide films. The reason for this is that the conventional technology uses a slitter method in which wide films are cut using a slitter, so if the film is made too thin,
This is because undesirable tearing occurs in the film. Therefore, in the slitter method, the width is narrow (maximum about 70 mm).
, thick films (approximately 0.125 mm or more) were being processed.
