Abstract
A high-speed binder application device for wrapping binder material about a bundle of buffer tubes that contain optical fibers includes a pair of opposite facing binder heads mounted on a pair of hollow shafts, each shaft being driven in rotation by a concentric drive. Each binder head includes a light-weight synthetic guide drum that dispenses binder material from a reel and onto the bundle of buffer tubes as it is advanced through the hollow shafts. The lightweight and high strength of the synthetic guide drums allows the drums to be rotated at speeds in excess of 4000 RPM. Each drive is concentrically mounted on its respective shaft which reduces or eliminates the shaft bending loads associated with prior belt-driven binder devices, and thus reduces vibrations at higher rotational speeds.
