摘要： Non-woven fabrics are manufactured using a carding machine with outlet comb, a blamire feed or spreader/batt-making machine with cylinders for depositing a web of fibers, and one or more needling devices. The surface weight of the web delivered by the carding machine to the blamire feed is modified by varying the speed of the comb as a function of the changing positions of the cylinders whereby a batt of variable surface weight over its width is obtained so as to counteract the distortions of surface weight distribution produced by the needling devices.
