A collator comprises a first hopper for storing signatures having a first characteristic and a second hopper for storing signatures having a second characteristic. A plurality of collating pockets move relative to the first and second hoppers and receive signatures from the first and second hoppers. An actuatable feeder, when actuated, feeds an individual signature from one of the first and second hoppers. A memory stores a predetermined number corresponding to the number of individual signatures to be delivered from the first hopper. The feeder is controlled to initially feed individual signatures from the first hopper to the plurality of pockets until the number of individual signatures delivered equals the predetermined number and then to feed individual signatures from the second hopper to the plurality of pockets without stopping movement of the pockets relative to the first and second hoppers.
