Method and device for preventing damage or snagging of flat plate-like materials

摘要

The invention relates to a method and apparatus for preventing damage or hooking during separation of stacked, plate-shaped flat materials, in particular metal sheets (7), wherein a sheet-conveying machine, particularly sheet printing presses, wherein the flat material in each case first and foremost lies, delivered in imbricated stream (8 is) aligned precisely positioned and then transported away for further processing under the imbricated stream exiting sender separation, wherein in the region of the separation at least one side portion (34) of the uppermost and foremost located flat material (8) relative to the including shingled arranged flat material (9) by at least one blast air (29 ), preferably according to the principle of the beam effect or lift is raised, the blown air stream (29) is oriented such that it flows (along the surface 13) or a portion of the surface (13) of the foremost located flat material (8).
