System for supplying literature inserts to a carton-packing machine
First Claim
1. In combination:
- a main conveyor for conveying a succession of orders in a main direction past a transfer location;
an upwardly open holder pocket at the transfer location defining a vertical transfer plane and formed byan outer plate substantially lying on and parallel to the transfer plane andan inner plate extending at a small acute angle to the transfer plane;
a plurality of openable transfer clips displaceable past the pocket with the clips moving vertically upward in the transfer plane as they pass the pocket;
a pair of rollers spaced to one side of the transfer plane immediately above the pocket, the inner plate having an upper edge generally at the rollers;
folding means including a pair of belts having juxtaposed stretches and spanned over the rollers for making folded literature packs, conveying the folded literature packs while compressed between the belts to the rollers, and dropping the folded literature packs one after the other from between the rollers and belts into the pocket while maintaining the packs compressed and preventing them from unfolding, the plates being sufficiently close to prevent the packs they hold from unfolding; and
control means for opening the clips as they approach the pocket and closing them generally when they reach the pocket for gripping the packs and lifting them out of the pocket.

Abstract
A main conveyor for conveying a succession of orders in a main direction past a transfer location is associated with an upwardly open holder pocket at the transfer location defining a vertical transfer plane. A plurality of openable transfer clips on an endless conveyor element are displaceable past the pocket with the clips moving vertically upward in the transfer plane as they pass the pocket. A pair of belts having juxtaposed stretches and spanned over a pair of downstream rollers spaced to one side of the transfer plane immediately above the pocket drop literature packs one after the other from between the rollers and belts into the pocket. A cam arrangement opens the clips as they approach the pocket and closes them generally when they reach the pocket for gripping the packs and lifting them out of the pocket.
