Definitions

the invention relates to a device for closing the gap between the ends of an intaglio printing plate clamped on a forme cylinder according to the preamble of patent claim 1.
a plate was covered by a pressure piece (patent application P 33 08 807.1). In the area of the plate ends this creates a continuous, uniform surface without elevations and depressions; however, an exact continuation of the surface of the forme cylinder is not guaranteed. It depends on the exact positioning of the plate in relation to the gap.
the forme cylinder 1 of a sheet-fed or rotary intaglio printing machine is provided with a groove 2 which runs along the forme cylinder axis and widens from the cylinder surface to the cylinder center, into which the intaglio printing plate 3 clamped on the forme cylinder is folded with both End 4 is hooked at an acute angle.
a plate 7 is placed over the two end sections 6 of the intaglio printing plate, which is elastically attached to the underside of a box-shaped retaining strip 8 by means of rubber or spring washers 30 and is elastically bendable or shaped according to the contour of the cylinder surface .
the retaining strip 8 is fastened to the movable cylinder housing 9 of a pneumatic working cylinder 10, the piston of which - connected to a guide rail 11 - is fixed.
the working cylinder is accordingly a guide and, at the same time, a drive element for the plate 7 to be moved onto the form cylinder 1 by means of the holding bar.
the holder for the plate designed in this way is opposite to both end faces of the form cylinder and is shown in the drawing for only one side.
the guide rail 11 is pivotably mounted on the axis of the forme cylinder or on an axis 12 coaxial with this and can be fixed by means of a clamp 13.
the axis is held in a U-shaped leg 14 which is fixed by means of a locking screw 15 on the stub shaft 16 of the forme cylinder 1.
a centering device 17 which consists of a pair of centering rails 19 which is also pivotably mounted on the axis 12 and can be fixed by means of a clamp 18, with recesses 20 running radially to the axis and a centering bar 21 which is accommodated therein without play and extends over the entire length of the forme cylinder, which is wedge-shaped towards the gap 5.
the centering bar As can be seen in FIG. 2, after the centering bar has been lowered into the gap 5 by hand, it is pressed into it by its own weight or with the aid of springs 22 supported on the two centering rails.
the pair of centering rails is placed on the center of the gap radius pulled, which of course presupposes that the recesses 20 serving as guides are arranged exactly on the rail center line, and then fixed by means of the clamps 18 by the set screws 23 *.
the pair of centering rails is thus an alignment aid for the pair of guide rails 11 arranged immediately next to it and including it. This is now pivoted into the same position as that of the pair of centering rails (FIG. 3) and is fixed with it by means of congruent holes 24 by means of pins 25, whereby the pair of guide rails in the aligned position is brought.
each guide rail is provided with an additional guide 32 which extends radially with respect to the forme cylinder axis, into which the centering bar can be inserted via a lateral outlet 33 and can be removed from it before the plate 7 is lowered.
the centering device consists of a radiation source which is aligned with the forme cylinder surface and generates a bundled light beam 34, for example from laser optics or a shadow mask 35, over which a light source 36 is arranged, which is in place of the centering bar 21 a carrier connecting the centering rails 19 or is fastened to the holding bar 8 above the plate 7.
a radiation source which is aligned with the forme cylinder surface and generates a bundled light beam 34, for example from laser optics or a shadow mask 35, over which a light source 36 is arranged, which is in place of the centering bar 21 a carrier connecting the centering rails 19 or is fastened to the holding bar 8 above the plate 7.
the latter arrangement requires that the plate 7 is transparent. This also gives the advantage that the filling process of the gap 5 and the tightness between the plate and its support surfaces can be observed.
a radiation source 28 for example a fluorescent tube, is pivotably held on the holding strip 8 for the plate 7 by means of a hinged holder 29. After the filling process, the radiation source extending over the entire length of the gap 5 is pivoted over the transparent plate and is thus effective towards the gap.
the surface which has arisen in the manner described above and connects the two end sections 6 of the intaglio printing plate 3 can be used without reworking, so that the forme cylinder 1 can be removed for use in the printing press after the holder of the plate 7 has been pivoted back.
