DE 19930800 A UPAB: 20000405 NOVELTY - Fibers produced from wood shavings chips are conveyed through a tubular dryer whose end section forms a glue application zone in which the larger diameter reduces the fiber conveying speed and creates turbulent flow. The turbulence is increased by axially injecting additional air with the binder into the center of the glue application zone curing zone whose length is 5-10 times the diameter. DETAILED DESCRIPTION - Preferred Features: The air is injected in a ring around the binder injection nozzle and at the same angle. USE - For production of high medium or low density fiber board ADVANTAGE - Uniform dispersal of the binder on the fibers is achieved together with a reduction in binder usage
