Abstract
A feeder has a rotary bowl with a highly resilient foam plastic insert providing a V-shaped annular trough to which objects are fed, a rotary feeder head whose axis is inclined to the axis of the bowl, and a nozzle wheel carried by the feeder head with a number of suction nozzles arranged so that the nozzles pick up successive objects from the bowl. As the nozzle wheel rotates, ports on the nozzle wheel register with stationary ports to which compressed air is supplied, and cause the suction to be released and a blast of compressed air to be blown through an annular array of discharge openings.
