Abstract
A product feed device includes multiple drivers mounted pivotally between a pair of parallel and opposed endless chains. When pivoted to an active position, each driver engages a product and pushes the product along a path. A set of cams is disposed upstream of the path. Each of the cams is alternatively positionable in alignment between the chains, to engage successive drivers to either set or reset the drivers as they encounter the cam. The cams set and reset successive drivers in different repeating sequences, thus to enable switching from one selected spacing between actuated cams to another, depending on which cam is in the operating position. A pair of opposed guide members extend longitudinally along the path to confine the chains against transverse movement, and maintain each of the drivers in its selected orientation, whether set to active or reset to a bypass position.
