ABSTRACT:
Apparatus for conversion of a stream of partly overlapping sheets into a row of fully overlapping sheets has a first conveyor which transports a growing row of sheets at right angles to the planes of sheets, and a composite second conveyor which defines a downwardly extending path wherein successive sheets of the stream descend onto the first conveyor to accumulate between spaced-apart distancing elements of the first conveyor. The advancement of successive sheets all the way onto the first conveyor is assisted and promoted by oscillating fingers which engage the oncoming sheets immediately above the first conveyor and intermittently push such sheet in the direction of forward movement of the growing row to provide room for the oncoming sheet. A fully assembled row is lifted by a carriage and its outermost sheets, or suitable rigid panels which are inserted at the outer sides of the outermost sheets, are engaged by the jaws of a trolley which transports the row to a further processing station in a bookbinding machine. The panels can be inserted by hand or automatically; in the latter instance, the distancing elements are slotted and cooperate with slotted displacing members which eliminate bulges in the rearmost sheet of the fully assembled row and in the foremost sheet of the growing row on the first conveyor to facilitate automatic insertion of panels by a piston rod and a set of elastic rollers.
