AbstractA fiber blending system includes a number of feeders which dump fibers onto a conveyor. Each feeder includes a weigh pan into which fibers are fed. The weigh pan is pivotally mounted to the feeder and counterbalanced. Also connected to the weigh pan is a single load cell which monitors the weight of fibers in the pan. The load cell is connected to the weigh pan by a single wire about which vibration damping is disposed. Once a set weight of fibers has collected in the pan, feeding stops until a dump command is given related to the position of the conveyor. When the conveyor is in the appropriate position, all feeders then dump fibers at their respective set weights. The blending system is controllled by a programmable controller which monitors for three malfunctions. If fibers fail to dump after a dump command is given, if an excessive time occurs during which the pans are filling without reaching the set weight and when a predetermined number of heavy dumps occur, an alarm is generated.
