Abstract: For use primarily in high-speed collating of multiple sheet inserts for mailing pieces, a series of rotary feed station means each having a plurality of gripping means are located above collating insert conveyor means. Each feed station feeds an insert, usually a single folded sheet, onto the conveyor at timed intervals such that the second feed deposits its insert onto the first insert, the third is deposited onto the first and second, etc., until all desired sheets are collected for inserting into an envelope.
