摘要:
A method and an apparatus for producing a pattern forming sheet efficiently. The method and apparatus for producing a sheet having a first pattern formed on at least one side by a first roll forming die and a second pattern formed by a second roll forming die is characterized in that the rotational angular speeds of the first and second roll forming dies are substantially equalized and relative positional variation of the first and second patterns is substantially minimized by synchronizing the phases of the periodic positional variation caused by the rotation of the rolls.
