Abstract
Overfeed prevention method and apparatus operative during the purging of a pneumatic line which, between purges, conveys fiber material from a source to one or more of a plurality of stations. Whenever a station indicates a demand for fibers, control circuitry causes fibers to be supplied to that station and after all the demanding stations have been so supplied, the line is purged of fibers by operating at least one (preferably the last fed one) of only those stations which received fibers during a predetermined number of previous cycles to the exclusion of and thereby preventing the overfeed of any station that did not demand to be fed during that predetermined number of previous cycles. The stations have a priority sequence so that if, during the feeding of a given station, a station having a higher priority indicates a demand, the feeding of the given station is interrupted in favor of the station having the higher priority.
