WebIt is well understood that with current headbox systems, the in-plane fiber orientation and formation are coupled. That is, by increasing the convergence angle of the headbox nozzle, formation improves and fiber orientation anisotropy (i.e., MD/CD ratio approaching 1.0) increases. Consider a typical hydraulic headbox, as shown in Figure III.1. WebOpen Type Headbox. Open headbox (with two-distribution rolls) stock flow process,perforated rolls and other mainly equipment are similar with air-cushion headbox. A gravity head of stock is used to give the corrected by pond level.Open headbox‘s work speed is mainly slow. WebThe headbox is also known as flowbox. Headbox Types: Normally the headbox is categorized into three types such as open type, air pad type and hydraulic type. Among them the hydraulic headbox is designed for a high speed modern paper machine (above 300 m/min) whereas open headbox is used in low speed paper machine. hawthorn theatrical hire
