Patent ID: 7926758

Claim:
An apparatus for roll-to-roll processing comprising: a first roller configured to convert the transmission of a roll of flexible material from a first direction to a second direction, the first direction and the second direction forming a first angle with respect to one another; a second roller spaced apart from the first roller and extending transversely with respect to the first roller, the second roller being configured to convert the transmission of the roll of flexible material from the second direction to a third direction, the second direction and the third direction forming a second angle with respect to one another; a third roller spaced apart from the second roller and extending transversely with respect to the second roller, the third roller being configured to convert the transmission of the roll of flexible material from the third direction to a fourth direction, the third direction and the fourth direction forming a third angle with respect to one another; and a fourth roller spaced apart from the third roller and extending transversely with respect to the third roller, the fourth roller being configured to convert the transmission of the roll of flexible material from the fourth direction to a fifth direction that is substantially parallel to the first direction, wherein the roll of flexible material includes a first side and a second side, and wherein the first roller, the second roller, the third roller and the fourth roller each contact the same one of the first side and the second side of the roll of flexible material during the transmission of the roll of flexible material.
