Turning bar apparatus |
摘要 |
A turning bar apparatus includes a stationary turning bar assuming the form of a hollow cylinder and adapted to change the running direction of a web looped therearound and a compressed-air supply unit for supplying compressed air into the hollow interior of the turning bar. A plurality of air outlet openings are formed through the wall of the turning bar and are arranged in rows and along the longitudinal direction of the turning bar. At least a single row of air outlet openings is arranged in an upstream portion of a web-looping region extending between an upstream end of the web-looping region and a circumferential center of the web-looping region. At least a single row of air outlet openings is arranged in a downstream portion of the web-looping region extending between the circumferential center of the web-looping region and a downstream end of the web-looping region.
