Abstract:
1. A printing unit for a web-fed rotary printing press comprising: first and second spaced, parallel press side frames and defining press frame inside spacing distance between inner sides of said first and second press side frames; at least one printing group rotatably mounted between said side frames and within said inside width, said at least one printing group including a transfer cylinder and a coordinating forme cylinder, each of said cylinders having a barrel with spaced first and second barrel end faces and with spaced first and second cylinder end drive journals formed integrally with said first and second barrel end faces; an inking unit including rollers adapted to cooperate with said at least one printing group; first and second linear bearings each supporting one end of at least one of said printing group cylinders in said inside width between said spaced side frames for movement with respect to said spaced press side frames and in said inside width along a travel path in a linear direction of adjustment generally parallel to said press side frames, each of said first and second linear bearings including spaced first and second parallel, individual linear bearing elements, each of said spaced, first and second parallel, individual linear bearing elements being fixedly secured separately to a respective one of said inner sides of said first and second side frames, both of said spaced, individual linear bearing elements in each of said first and second linear bearings being spaced at a common distance from an associated one of said barrel end faces; a bearing unit for each end of said at least one linearly movable one of said printing group cylinders and including one of said first and second linear bearings; a structural unit formed by said at least one linearly movable printing group cylinder of said at least one printing group and including said transfer cylinder and said coordinated forme cylinder, said structural unit including said barrel, said first and second end journals and said bearing unit for each end of said at least one linearly movable printing group cylinder and including said linear bearings, said bearing units being located at said first and second end journals, said structural unit having a length which is not greater than said side frame spacing distance; a bearing block having a radial bearing supporting each said cylinder end journal of said at least one linearly movable printing group, said bearing block being supported between, and being movable with respect to said fixedly secured, spaced first and second parallel individual linear bearing element of each of said linear bearings of said bearing unit for movement of said bearing block and said at least one linearly movable printing group cylinder supported by said bearing block along said travel path in said linear direction of adjustment along said spaced first and second parallel individual linear bearing elements; and an adjustable travel path limiting element in said bearing unit and engageable with said bearing block to adjustably limit said movement of said bearing block of said at least one linearly movable printing group cylinder along said travel path in said linear direction of adjustment with respect to said bearing unit, said adjustable travel path limiting element being movable in a movement direction to limit said travel path of said at least one of said printing group cylinders.
