<p>Method and apparatus for placing plate-like elements (10) within a processing machine (1): the machine including a feeder (20) for placing the elements (10) in a plurality of gripping members (31) of a conveyor (30) in successive stations (3, 4, 5). The feeder (20) has a fixing device (21) for elements. The feeder (20) is driven by a computation and control unit (40). The method includes successive steps during advancement of each plate-like element (10) of measuring the longitudinal and angular placement error of the plate-like element (10) relative to a theoretical position, by detecting its front or rear edge, controlling the feeder (20) according to the measured placement errors, activating the fixing device (21) to attach the plate-like element (10) to the feeder (20), then measuring the longitudinal, the transverse and angular placement error of the plate-like element (10) attached to the feeder (20), relative to a theoretical position, by detecting register marks (12) printed on the element (10).</p> |
