Abstract

An alignment monitoring device on rotary printing machines includes a plurality of installed components, respectively, having at least one alignment indicator applied thereto, the alignment indicator having equipment for indicating permissible tolerances for positional deviations of the respective installed component, and equipment for indicating positional deviations incurred by the respective installed component, and a device for protecting the alignment indicator against being manipulated.

Claims

1. A combination comprising a rotary printing machine and at least one alignment monitoring device for alignment monitoring of the rotary printing machine, the printing machine including a plurality of installed components, wherein at least one of the installed components includes at least one alignment monitoring device;

said alignment monitoring device including means for indicating positional deviations of said components from the time of installation of the printing machine in at least two planes;

retaining means connected with said alignment monitoring device for retaining said alignment monitoring device in its original position on said installed components, and manipulation securing means connected with said alignment monitoring device for securing said monitoring device against manipulation during operation of said rotary printing machine, wherein said monitoring device is operative for indicating loss of alignment of said installed components from their original aligned positions.

2. The combination according to claim 1, including in said monitoring device means for indicating tolerances, and wherein said monitoring device includes means for indicating tolerances in two planes.

3. The combination according to claim 1, wherein said alignment monitoring device is an annular spirit level.

4. The combination according to claim 1, wherein said alignment monitoring device comprises at least one rectilinear spirit level.

5. The combination according to claim 1, wherein said alignment monitoring device comprises at least one annular spirit level and at least one rectilinear spirit level.

6. The combination according to claim 1, wherein said alignment monitoring device comprises two rectilinear spirit levels disposed perpendicularly to one another.

7. Device according to claim 1, wherein said retaining means include sealing means in operative engagement with said alignment monitoring device for sealing said alignment monitoring device in a sealed position.

8. Device according to claim 7, wherein said sealing means include at least one of lead sealing and caulking.
