Abstract
A method for collecting long glass fibers produces substantial lattice uniformity, eliminates the need for binder, and results in a generally rectangular wool pack which displays significant compressibility and recovery desired for commercial products. Generally spiral flow of fibers in the veil is captured on collecting conveyors and conveyed through direct forming apparatus with generally minimal disturbance of the spiral relationship between glass fibers. Further, a system is disclosed for producing wool insulation products of long glass fibers in accordance with the method. The principles and practices of the method and system may further be employed with short fibers to produce a wool pack of generally oriented short fibers.
