Abstract
Systems and methods for modifying, altering, constructing, or retrofitting an existing newspaper press having a first cut-off length, to have a second cut-off length which is different from and generally less than the first. These systems and methods generally provide for the machining of new bore holes into the existing press unit frame. The new bore holes will generally completely encompass the old bore holes and allow for linear translation of the axes of rotation of the new cylinders relative to the positions of the axes for the old cylinders.
Claims8
A system for machining new bore holes for mounting blanket and plate cylinders in a printing press unit, the system comprising:
- said printing press unit;
- a fixture, mountable to and removable from said printing press unit, comprised of a rigid material;
- at least one alignment hole machined through said fixture;
- and
- at least one bore hole guide machined through said fixture;
- wherein said at least one alignment hole is aligned to at least one of a plate bore hole or a blanket bore hole of said printing press unit;
- and
- wherein, when said at least one alignment hole is so aligned, said bore hole guide indicates a position to machine a new hole in said printing press unit.
A system for machining new bore holes for mounting blanket and plate cylinders in a printing press unit, the system comprising:
- said printing press unit;
- a fixture, mountable to and removable from said printing press unit, comprised of a rigid material;
- at least one alignment means in said fixture wherein said at least one alignment means may be aligned to at least one of a plate bore hole or a blanket bore hole of said printing press unit;
- and
- at least one bore guiding means in said fixture wherein when said at least one alignment means is aligned to said at least one of said plate bore hole or said blanket bore hole, said bore guiding means guides boring of a new hole in said printing press unit.
A system for machining new bore holes for mounting blanket and plate cylinders in a printing press unit, the system comprising:
- said printing press unit;
- a first fixture comprising:
- a first frame, mountable to and removable from said printing press unit, comprised of a rigid material;
- a first alignment hole machined through said first frame;
- and
- a first bore hole guide machined through said first frame;
- wherein said first alignment hole is aligned to a blanket bore hole of said printing press unit;
- and
- wherein, when said first alignment hole is so aligned, said first bore hole guide indicates a position to machine a first new plate bore hole in said printing press unit;
- and
- a second fixture comprising;
- a second flame, mountable to and removable from said printing press unit, comprised of a rigid material;
- a second alignment hole machined through said second frame;
- and
- a second bore hole guide machined through said second frame;
- wherein said second alignment hole is aligned to said new plate bore hole of said printing press unit;
- and
- wherein, when said second alignment hole is so aligned, said bore hole guide indicates a position to machine a new blanket bore hole in said printing press unit.
