Definitions

the invention relates to a device for covering the cylinder pit of a cylinder of a rotary printing press with an insert piece which can be moved in the radial direction by means of an adjusting spindle extending parallel to the cylinder axis and is designed on its outside as a section of the cylinder jacket surface.
a device that enables an adjustment of the height of the insert is known from DE-PS 236 935.
two setscrews are provided, which are supported on the cylinder with one end, while the other end is screwed into the insert. These adjusting screws can practically only be adjusted when the insert is removed; an exact height adjustment of the insert is only possible by repeated testing.
the invention has for its object to provide a device of the type mentioned in such a way that the insert is easily and free of play adjustable to an accurate height in the cylinder pit.
the invention can be used not only in rotogravure printing machines to ensure a perfect squeegee function, but also in other rotary printing machines, in particular for offset or litho printing, in order to avoid sudden changes in the pressure between two cylinders during the passage through the pit. These sudden changes in the pressure lead to streaks of different color intensity on the printed copies.
the cylinder designated overall by 1 which is a blanket cylinder of an offset rotary printing press, has a cylinder pit 2 in which two clamping spindles 3 are arranged for fixing and tensioning the two ends of a blanket 4.
the cylinder pit 2 is closed on both sides by an end wall 5, only one of which is shown.
an adjusting spindle 6 which extends parallel to the axis of the cylinder 1 and which has an adjusting cam 7 in the center of the cylinder.
the adjusting spindle 6 is mounted at one end in the end wall 5 and at the other end in a bearing 8 which is firmly connected to the cylinder.
the adjusting spindle 6 has a collar 9 on the inside the end wall 5 rests.
the end of the adjusting spindle 6 projecting outwards through the end wall 5 has a polygonal projection 10 and is also provided with a thread 11 onto which a clamping nut 12 can be screwed.
a washer 13 is arranged between the clamping nut 12 and the end wall 12.
the adjusting cam 7 engages with a tight fit in a bore 14 of an insert 15 so that it can rotate in the bore 14 without play.
the outer surface of the actuating cam 7 has a circular shape and is eccentric to the center of the spindle 6. When placed correctly, this construction has the advantage that the same angle of rotation of the actuating cam results in approximately the same radial adjustment paths of the insert. Basically you can
the insert 15 consists of an inner part 16, which has the bore 14, and an outer part 17, the outer side 18 of which is formed as a section of the outer surface of the cylinder 1.
the outer part 17 has a flange 20 on each of the two end faces 19.
a screw 21 engages through each flange 20 and can be screwed into a thread in the inner part 16. After loosening the screws 21, the outer part 17 can be removed to the outside through the cylinder pit 2. Now the blanket 4 can be removed or replaced.
the outer part 17 carries an extension 22 which engages in a corresponding groove 23 in the top of the inner part 16. In order to prevent undesired rotation of the inner part 16, it has an extension 24 which engages in a groove 25 of the cylinder 1.
the insert 15 extends only over a short section of the length of the cylinder pit 2.
the width of the insert 15 corresponds to the width of the actuating cam 7.
two or more insert pieces can also be provided.
a bearing is then expediently arranged directly next to the actuating cam in order to prevent the actuating spindle from bending under the forces acting on the insert and thus to prevent a change in position of the outside of the insert.
the clamping nut 12 is loosened and then the adjusting spindle 6 is rotated by means of a key which overlaps the polygonal extension 10.
the adjusting cam 7 moves the insert 15 approximately in the radial direction.
the clamping nut 12 is tightened again and thus the adjusting spindle 6 is fixed with the insert 15.
