The GL&V Pneumatic (Air Pad Rectifier Roll) Headbox is ideal for very low speed fourdrinier applications on all grades of pulp and paper. It is also instrumental in enhancing products, like fluff pulp, where bulk, caliper, density and tensile ratio qualities are essential for excellent fiberization. The dimensional stability and overall product quality for slow speed applications such as market pulp and dissolving pulp grades is also significantly improved with a BTF Pneumatic Air Pad Rectifier Roll Headbox with Dilution Profiling. The BTF Dilution Control System, exclusive from GL&V, employs high-performance state-of-the-art dilution profiling which provides unparalleled CD 2-Sigma Dry Weight Profile Control. Reduced variability in CD weight distribution translates into reduced sheet caliper variation, and very often provides reduced moisture variability. These changes can result in significant energy savings through more efficient pressing and better face contact through the dryer sections, and can positively affect coating operations. BTF Dilution Profiling (a.k.a. Consistency Profiling) improves sheet quality and machine productivity with as little as 10% dilution water. The natural stock delivery of the BTF System improves sheet edges and increases usable sheet width when compared to conventional tapered header technology. The BTF also acts as a highly efficient and effective pulsation dampening device. The flow turn down ratio of the BTF Distributor is unmatched by any other flow spreading technology, thereby providing new and existing paper machines with substantial flexibility in their grade mix.

The BTF Dilution Control Module provides substantial improvements in CD weight control, and helps to improve fiber orientation profiles (TSO). Tensile ratio profiles (TSI) as well as sheet formation is further enhanced when employed with a full BTF Headbox System – Air Pad Rectifier Roll or Hydraulic. These extremely versatile & effective systems consist of three separate modules, each of which bring significant performance enhancement over conventional headbox technologies. The BTF modules can even be installed separately to provide an inexpensive, phased approach to achieving world class performance. With our installation list growing rapidly, GL&V is poised to be the world leader in Headbox Dilution Control Technology.

GL&V’s Pulp & Paper Division proudly announces their full and exclusive ownership of BTF technology and has exclusive rights to market the BTF system world-wide.
