Abstract
A multi-color web-fed rotary printing press is usable for job printing. Several printing devices are arranged as several bridge printing units which are supported by frames, at least one of which is shiftable in a horizontal direction. The bridge printing units are arranged on a lower horizontal plane and a printed web dryer is situated on an upper horizontal plane. The resultant printing press has a reduced overall size.
Claims15
A multi-color web-fed rotary printing press usable for job printing comprising:
- a printing system disposed at a first plane, said printing system including a plurality of bridge printing units disposed above each other, each of said plurality of bridge printing units being separable into first and second sections, said first section of each of said bridge printing units having a first printing cylinder and a first rubber blanket cylinder, said second section of each of said bridge printing units having a second printing cylinder and a second rubber blanket cylinder, said first and second blanket cylinders in each of said bridge printing units being engageable with each other to print a web passing vertically therebetween;
- a first frame section, said first sections of said plurality of said bridge printing units being mounted on said first frame section;
- a second frame section, said second sections of said plurality of said bridge printing units being mounted on said second frame section;
- means for moving at least one of said first and second frame sections in said first plane with respect to the other of said first and second frame sections so that said first and second frame sections can be separated by a horizontal distance from each other to separate said first and second blanket cylinders in said plurality of bridge printing units from each other;
- a roll changer for supplying a paper web to said printing system, said roll changer being disposed at said first plane;
- and
- a drying chamber for receiving a printed web from said printing system, said drying chamber being disposed above said roll changer and in a second plane above said first plane.
A multi-color web-fed rotary printing press usable for job printing comprising:
- a printing system including a plurality of bridge printing units disposed above each other at a first plane, each of said bridge printing units being separable into first, second and third sections, each of said bridge printing units including first and second printing cylinders, first and second blanket cylinders and first and second inking systems;
- a first frame section, said first printing cylinders and said first inking systems being mounted on said first frame section;
- a second frame section, said second printing cylinders and said second inking systems being mounted on said second frame section;
- a third frame section, said first and second blanket cylinders being mounted on said third frame section;
- means for supporting said first and second frame sections for movement with respect to said third frame section, said third frame section being situated between said first and second frame sections, said first and second frame sections each being separable by a horizontal spacing distance from said third frame section;
- a roll changer for supplying a paper web to said printing system;
- and
- a drying chamber for receiving a printed web from said printing system, said drying chamber being disposed in a second plane above said first plane.
