Abstract: An improved jogger includes a sidewall with a guide groove, a chain defining a closed path including a sloped loading end and a straight transport section, the sloped loading end being angled toward the transport section in the direction of the travel of the chain at least two sprockets, the sprockets defining the slope of the sloped loading end of the closed path, a plurality of fingers coupled to the chain at spaced apart intervals, the fingers receiving flat articles therebetween at the sloped loading end and conveying the articles along the horizontal transport section and a plurality of guides coupled to the fingers, the guides engaging the guide groove and orienting fingers in a position perpendicular to the horizontal transport section as the fingers are carried into the sloped loading end.

Abstract: A method of singulating and feeding a random mix of thick and thin flat articles includes: (a) sensing whether a flat article is positioned on a feed conveyor in a position for removal from the feeder conveyor with a sensor, (b) advancing the feed conveyor with a first motor an incremental step to place a series of flat articles positioned on edge in a position for removal from the feed conveyor each time the sensor detects the absence of a flat article for removal from the feed conveyor, (c) counting each incremental advance of the feed conveyor, (d) incrementally advancing the stack of flat articles with a jogger driven by a second motor after the feed conveyor has moved a predetermined number of incremental steps to load additional flat articles on the feed conveyor, the jogger tending to edge the flat articles for removal from the feed conveyor; and (e) repeating steps (a)-(d) while sequentially removing flat articles from the feed conveyor on a one-by-one basis as the feed conveyor is advanced.
