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.

An apparatus for feeding, weighing and releasing a predetermined quantity of fiber to a conveyor or the like in reoccurring cycles whereby the quantity of fiber released in each cycle is maintained at an essentially constant and preselected level, said apparatus including weigh pan means for receiving and collecting said fiber therein, said weigh pan means having selectively operable means for releasing the fiber collected therein, and fiber feeding means for selectively delivering a quantity of fiber to said weigh pan means, the improvement comprising: (a) means for sensing the weight of said fiber collected in said weigh pan means during each said cycle and generating a signal indicative of said weight; and (b) control means for receiving said generated signal, determining the actual weight of fiber released from said weigh pan after each release thereof by said releasing means, comparing said actual weight with a constant preset weight corresponding to the weight desired to be released during each said cycle, and controlling said fiber feeding means to vary the weight of fiber delivered to said weigh pan means during the next said cycle by an amount that is a predetermined fractional portion of the difference between said actual weight and said preset weight for the immediately preceding cycle.
