  • Apparatus and system for roll-to-roll processing
    Patent number: 7926758
    Abstract: An apparatus for roll-to-roll processing includes a first roller for converting the transmission of a roll of flexible material from a first direction to a second direction substantially orthogonal to the first direction, a second roller spaced apart from the first roller and extending transversely with respect to the first roller for converting the transmission of the roll of flexible material from the second direction to a third direction substantially orthogonal to the first direction and the second direction, and a third roller spaced apart from the second roller and extending perpendicularly with respect to the first roller for converting the transmission of the roll of flexible material from the third direction to a fourth direction, wherein the roll of flexible material includes a first side and a second side, and wherein the first roller, the second roller and the third roller contact the same one of the first side and the second side of the roll of flexible material.
