ABSTRACT:
An apparatus and method for arranging, at a predetermined spacing on a reception conveyor, objects originating in an unevenly spaced manner from a delivery conveyor. The delivery conveyor is driven with continuous motion. The reception conveyor is driven with intermittent motion. The apparatus comprises a flexible closed loop member lying in a horizontal plane. A first portion of the flexible loop extends parallel to the end part of the delivery conveyor and a second portion extends parallel to the initial part of the reception conveyor. A series of suckers is distributed along the flexible member and mobile vertically by means of cams disposed along the first and second portions for causing the suckers to move close to and away from the delivery and reception conveyors. A distributor member is arranged to connect and disconnect the suckers cyclically to and from suction means for taking the objects from the delivery conveyor and depositing them respectively on the reception conveyor. The speed of the flexible member is constant and different from that of the delivery conveyor. The reception conveyor stroke is arranged to attain a speed equal and concordant with that of the flexible member during the intermittent advancement.
