Modular printing unit
View Patent ↗In order to provide a printing unit ( 1; 50 ) of modular design with the lowest possible expenditure on construction and high flexibility, the printing unit ( 1; 50 ) of modular design for printing webs ( 29 ) has a stand ( 2; 2′; 54 ), which is provided with at least one crossmember ( 3; 4; 51 ) at both ends (drive and operating side), printing cylinders ( 9 to 16 ) being mounted in the crossmembers ( 3; 4; 51 ) in such a way that a structural unit comprising crossmembers ( 3; 4; 51 ) and printing cylinders ( 9 to 16 ) can be taken completely out of and put into the stand ( 2; 2′; 54 ).
1. A printing unit of modular design for printing webs, comprising:
a stand having a drive side and an operating side;
at least one crossmember arranged at each of said sides of said stand, wherein said crossmembers are aligned horizontally or vertically;
printing cylinders mounted in the crossmembers and forming a structural unit of said printing unit with said crossmembers such that said structural unit comprising said printing cylinders mounted on said crossmembers is removably received in said stand of said printing unit; and
subunits comprising auxiliary subassemblies necessary for the printing process, said subunits being replaceably arranged between said crossmember and said stand, and abutting a respective plate cylinder of said printing cylinders, said auxiliary subassemblies including damping and inking units.
2. A printing unit of modular design for printing webs, comprising:
a stand having a drive side and an operating side;
at least one crossmember arranged at each of said sides of said stand, wherein said crossmembers are aligned horizontally or vertically;
printing cylinders mounted in the crossmembers and forming a structural unit of said printing unit with said crossmembers such that said structural unit comprising said printing cylinders mounted on said crossmembers is removably received in said stand of said printing unit, wherein said printing cylinders comprise rubber cylinders arranged for printing on one or both sides of the web running therebetween and one of said rubber-covered cylinders is mounted in a swinging arm for pivoting, wherein said swinging arm is pivotable about an axis of a plate cylinder associated with said one of said rubber-covered cylinders.
