Abstract:

In the article is analyzed the main features of geometric transformation - inversion and are set out their realization principles in movable - mechanical systems. Is considered the design grounded on the properties of inversion mechanism of sheet reverse device that is different from the existing ones due that discrepancy conditions of arranged on printing drums sheet girders has been minimized to almost zero. Are constructed the sheet transfer and sheet reverse devices kinematic scheme drive and driven links rotation angles corresponding diagrams that gives the possibility for arranged on printing and offset cylinders girders to maintain exact coordinates of combination with each other that provides the total avoiding of caused by this device defects.

Keywords: defect; printing machine; sheet transfer and sheet reverse device; design; inversion.
