Method for feeding a printing forme to a forme cylinder of a printing press
A printing plate is produced having at least one edge which has been cut so that it is parallel to a line of delimitation of the type area of the plate. The printing plate is fed to an impression cylinder of a printing press, in an axial direction of the impression cylinder by use of a plate feeding and alignment device. During the process of feeding the printing plate to the impression cylinder, the at least one edge of the plate, which was cut parallel to the type line of determination, is guided against at least one stop.
1. A method for feeding a printing forme to a forme cylinder of a printing press including:
providing a printing forme having a type area;
applying markings to at least one side of said printing forme which is to be bent down for forming a forme cylinder engaging end;
determining a boundary line of said type area using said markings;
trimming at least one edge of said printing forme parallel to said boundary line;
bending down said at least one side of printing forme bearing said markings;
providing a printing forme feeding device having at least one axially effective stop;
placing said printing forme on said printing forme feeding device;
using said feeding device for precisely positioning said printing forme on said forme cylinder in an axial direction of said forme cylinder; and
using said at least one axially effective stop for guiding said at least one trimmed edge of said printing forme.
2. The method of claim 1 further including providing at least two of said stops, positioning said two stops spaced from each other in said axial direction of said forme cylinder and passing said printing forme to be fed to said forme cylinder between said two stops.
3. The method of claim 2 further including using at least one of said at least two stops for aligning said at least one trimmed edge of said printing forme.
4. The method of claim 3 further including providing a second printing plate side spaced from, and parallel to said trimmed side and engaged said second printing plate side using said other of said at least two stops.
5. The method of claim 4 further including providing said other of said at least two stops having a spring force and using said spring force for pressing said other of said at least two stops against said second printing plate side.
6. The method of claim 1 further including applying said making to said printing forme during imaging of said type area.
7. The method of claim 1 further including trimming said at least one edge after imaging said printing forme.
8. The method of claim 1 further including bending down said at least one side of said printing forme at a bending angle of between 45° and 135°.
9. The method of claim 1 further including bending down said at least one side of said printing forme at a bending angle of 45°±10°.
10. The method of claim 1 further including bending down said at least one side of said printing forme at a bending angle of 90°±10°.
11. The method of claim 1 further including implementing said trimming of said at least one edge of said printing forme and said bending down of at least one side of said printing forme in the same direction.
