Shingled precisely spaced papers are carried off a first conveyance path on a moving belt at a first speed into a further conveyance path along which a set of spaced clamps which individually grasp each paper flow at a substantially constant lower transit speed. By gradually inserting a paper into an open clamp travelling alongside in a parallel path over a predetermined transfer zone length overlapping a plurality of successive clamps, the instantaneous nature of feeding a paper into a clamp is changed so that a higher paper feed speed can be tolerated. By inclining the shingled paper feed path downwardly over the transfer zone, the drag of the papers off the shingled array is reduced to prevent any tendency to misalign the papers from a seated position in the clamps.

In a conveyance system for transporting newspapers or the like by a succession of individual clamps, improved means for transferring the newspapers from a shingled array on a conveyor belt into the clamps for further transport thereby, comprising in combination, conveyor belt means for transporting a shingled array of said newspapers along a conveyor belt path into a transfer station at a speed presenting the leading edges of the newspapers spaced by a distance X for a given increment of time, clamp conveyance means for transporting a succession of spaced clamps in a path approaching the conveyor belt means and passing substantially parallel with a conveyor belt path section of the transfer station in the same direction before diverging therefrom at the end of a transfer zone encompassing a plurality of clamps, wherein the clamps are transported at a speed spacing the clamps a distance less than X for said increment of time, thereby permitting individual newspapers on the belt to move towards and overtake individual clamps within said transfer zone, cam means synchronously operable to open the clamp jaws and to close them gradually over said transfer zone to receive thereinto said newspaper leading edges and clamp them in place for transport by the clamp conveyor means as they are conveyed in part on said belt through the transfer zone and means operable after the newspapers pass the conveyor belt path transfer zone diverging the paths of the conveyor belt path and the clamp conveyance means to remove the newspapers from the belt in the grasp of the individual clamps, and insertion means comprising conveying solely by frictional contact of a shingled array of newspapers on the conveyor belt over a roller where the direction of the belt path is changed to a downwardly inclined direction for registering the leading edge of newspapers carried on the belt into the open clamps in the initial part of the transfer zone.
