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.
Claims17
A roll for applying a sizing composition to a fan of one or more fibers, 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.
A method of applying a sizing composition to a fan of one or more fibers, comprising the steps of:
- providing an element having a curved central axis;
- rotating said element about said curved central axis;
- applying a coating of sizing composition to said element as said element rotates about said curved central axis;
- and,
- conveying each fiber of said fan of one or more fibers over said element, whereby each fiber of said fan of one or more fibers contacts said element at an axial location along said element and moves over said element in a direction which lies substantially in a plane perpendicular to said central axis of said element at said axial location of said element, and whereby said sizing composition is transferred from said element to each fiber of said fan of one or more fibers.
A system for applying a sizing composition to a fan of one or more fibers, comprising:
- a element having a curved central axis, wherein each fiber of said fan of one or more fibers contacts said element at an axial location along said element and moves over said element in a direction which lies substantially in a plane perpendicular to said central axis of said element at said axial location of said element;
- and,
- a sizing delivery assembly for providing sizing composition to a surface of said element, said sizing composition being transferred to each of said fibers of said fan of one or more fibers when said fibers contact said element.
