In an off-line, free standing, parts-orienting and feeding device, selected parts are fed by a hopper to and oriented in a centrifugal or vibratory parts feeder unit, and then discharged to a programmed transferring arrangement. The latter includes a slide shuttle unit for alternately receiving discharged parts in a plurality or passages and aligning the part receiving passages with one or more pressurized air passages to blow the parts through selected transfer tubes to pick and placement devices which serve to place the parts continually one at a time on packaging materials being processed on one or more packaging machines. Limit devices on each transfer tube signal the slide shuttle unit to realign the parts receiving passages with the pressurized air passages to provide parts as required by each machine.
