  • Detail

The invention relates to a printing plate cylinder of a printing machine, which has a tensioning channel extending along the axial direction, in which a device for fixing the end of the printing plate of at least one printing plate that can be located on the printing plate cylinder is arranged. The front end of the printing plate can be fixed by a retaining element against a contact surface through a tensioning guide rail that can be moved in the tensioning channel. After the printing plate cylinder rotates, the reduction of area at the rear end of the printing plate refers to the material sample hooked on the extended tensioning guide rail after being pulled off by tensile load, Then the tensioning guide rail was pulled back to the ordinary railway again. After the 10000 ton heavy haul train was operated, the iron door end of the hydraulic control box was opened after tensioning the printing plate (5)
