Delivery apparatus for sheets or plates
Abstract
Abstract THE LOWERMOST ARTICLE OF THE PILE FROM WHICH THE SHEETS OR PLATES ARE TO BE DELIVERED IS SUPPORTED BY ITS FRONT AND REAR EDGE. A SUCTION BOX IS APPLIED AGAINST THE EXPOSED PORTION OF ITS UNDERSIDE AND IS MOVED LONGITUDINALLY IN ONE AND THE OTHER DIRECTION SO AS TO DISENGAGE THE EDGES OF THE SAID ARTICLE FROM THE FRONT AND REAR SUPPORTS OF THE PILE, WHILE THE OTHER ARTICLES OF THE PILE ARE RETAINED AGAINST HORIZONTAL DISPLACEMENT. THE SUCTION BOX IS LOWERED AND THE ARTICLE RESTING THEREON IS POSITIVELY PUSHED TOWARDS THE FEED ROLLERS OF THE MACHINE WITH WHICH THE DELIVERY APPARATUS IS ASSOCIATED. THIS SLIDING MOVEMENT MAY BE FACILITATED BY MOMENTARILY SUPPRESSING THE NEGATIVE PRESSURE WITHIN THE SUCTION BOX.
