An apparatus includes a first roll and a second roll on each of which a pattern is formed, a first motor and a second motor to rotate the respective rolls, a shaft direction supporting mechanism to support the second roll along a shaft direction and an axial position adjusting mechanism configured to move the shaft direction supporting mechanism along the shaft direction. The posture of the rotating shaft of the second motor is maintained constant at all times, and the second roll is moved in the shaft direction along the first roll, thereby adjusting the positions of both patterns on the first roll and the second roll along the shaft direction.

On at least the edge portion () of the lip portion () of a T-die (), a cladding layer () is provided. The cladding layer is formed by laser build-up welding to a base material with a powder of a corrosion resistant and wear resistant alloy comprising a nickel-based alloy or a cobalt-based alloy. The cladding layer has a metallographic structure in which metal borides are dispersed in a binder phase. The lip portion has high quality and has high durability. The manufacturing costs of the T-die can also be kept relatively low.
