An integrated capstan for use in fiber processing and testing apparatus. The integrated capstan features a fiber-engaging material that provides a contact surface for fibers. The hardness of the contact surface is controlled to minimize transfer of stress to the fibers to prevent damage to fiber coatings or fiber splice junctions during conveyance or screen testing of fibers during production. The fiber-engaging material includes a resilient material and an optional capping layer. The resilient material may be a lightly crosslinked polyurethane gel. Capping layers include polymers formed by UV curing of aliphatic urethane diacrylate compounds or moisture curing of diisocyanate compounds. |
