ABSTRACT:
A method for sorting paperboard blanks into groups of identical length blanks. When an order chanber is effected, the succeeding blanks formed in accordance with the new order are accumulated upon the preceding blanks in an orderly manner by intermittently driving a first conveyor so that the reduction ratio or speed differential becomes relatively small when a blank formed in accordance with the new order arrives at the first conveyor. In an alternate method, the succeeding blanks are positively disposed upon the preceding blanks fed to a first conveyor having a vacuum suction area defined therein by moving each preceding blank a desired distance, so that the vacuum suction area may be exposed behing the preceding blanks.
