ABSTRACT:
The feeder has a device which reciprocates across the bottom of a stack of articles so as to separate and feed the lowermost article of the stack during each feeding stroke of the device. The device has a pair of elongated members which extend in the direction of feed and are provided with friction padding along their uppermost surfaces for making firm contact with the article to be fed. Such members, working together as an integral unit, rise up into engagement with the article to slightly raise it along the engaged portions thereof above the rest of the device as the forward stroke is commenced, thereby warping the article along the leading edge thereof as such leading edge is at the same time tucked beneath a confining element at the front of the stack which is strategically spaced above the device a distance which permits the passage of only the lowermost article during each feed stroke. This has the effect of advancing only the lowermost article from the stack into a pair of high-speed nip rollers which grab the article and immediately commence withdrawing it the rest of the way out of the stack. When the nip rollers begin pulling on the article, the raised friction members respond by dropping down to their initial position below the upper surface of the feed device, which thereupon makes its return stroke in preparation for feeding the next article of the stack.
