Claims (9)

1. Способ приема задней кромки листа с предшествующего цилиндра листовой ротационной печатной машины с последующей передачей этой задней кромки листа на систему захватов, в частности на переворачивающий захват последующего барабана, при этом предусмотренный для приема задней кромки (6) листа вакуумный присос (4) накладывается на лист (1) в зоне этой его задней кромки (6) и во время приема листа движется по траектории, повторяющей профиль периферии цилиндра (2), после чего вакуумный присос (4), постоянно оставаясь в касательной плоскости к боковой поверхности предшествующего цилиндра, отводится под периферию барабана (3) для переворачивания листов, причем вакуумный присос (4) для натяжения листа на этом участке перемещения совершает относительное движение в направлении по касательной, отличающийся тем, что вакуумный присос (4) по достижении положения передачи листа на систему (25) захватов совершает относительное движение в направлении перемещения листа, а при закрывании захватов вакуумный присос (4) и переворачивающий захват (25) находятся в состоянии покоя друг относительно друга.1. The method of receiving the trailing edge of the sheet from the preceding cylinder of the sheet rotary printing press, followed by transferring this trailing edge of the sheet to the gripper system, in particular to the inverting gripper of the subsequent drum, while the suction cup (4) provided for receiving the trailing edge (6) of the sheet is superimposed on the sheet (1) in the region of its trailing edge (6) and during sheet reception moves along a path repeating the profile of the periphery of the cylinder (2), after which the vacuum suction cup (4), constantly remaining in the tangent plane to the side the surface of the preceding cylinder is discharged under the periphery of the drum (3) for turning the sheets, and the vacuum suction (4) for tensioning the sheet in this movement section makes a relative movement in the tangential direction, characterized in that the vacuum suction (4) upon reaching the gear position the sheet to the gripper system (25) makes a relative movement in the direction of movement of the sheet, and when the grippers are closed, the vacuum suction cup (4) and the turning gripper (25) are at rest relative to each other. 2.
