Abstract
A roll for applying a sizing composition to a fan of one or more fibers, providing a shaft having a curved central axis and a sleeve covering at least a portion of the shaft, the sleeve being rotatable relative to the shaft. Each fiber of the fan of one or more fibers contacts the sleeve at an axial location of the sleeve such that each fiber of the fan of one or more fibers lies substantially in a plane perpendicular to the curved central axis of the shaft at the axial location.
Claims10
A sizing application system for applying a sizing composition to a fan of one or more fibers, comprising:
- a roll comprising a shaft having a curved central axis, and a sleeve covering at least a portion of said shaft, said sleeve being rotatable relative to said shaft, wherein each fiber of said fan of one or more fibers contacts said sleeve at an axial location of said sleeve, and wherein each fiber of said fan of one or more fibers lies substantially in a plane perpendicular to said curved central axis of said shaft at said axial location;
- and
- a sizing delivery assembly for providing sizing composition to a surface of said sleeve, said sizing composition being transferred to each of said fibers of said fan of one or more fibers when said fibers contact said sleeve.
