Abstract
Method and apparatus for feeding, weighing and releasing a predetermined quantity of fiber in reoccurring cycles for use in a fiber blending operation or the like whereby the quantity of fiber released in each cycle is maintained at an essentially constant and preselected level, which includes means for sensing the actual weight of fiber dumped from a weigh pan or container, comparing such weight with a constant preset desired weight setting, and varying the weight of fiber delivered during the next cycle to compensate for any differences between the preset weight and the actual weight dumped during the preceding cycle.
