Definitions
- the invention relates to a device for holding two folded ends of an arcuate, flexible support according to the preamble of claim 1.
- a disadvantage of this clamping device is that the ends of the printing forms have permanent deformations due to the pressing into the circular segment-shaped section of the cylinder pit, which oppose multiple use of the printing forms.
- the deformed ends are difficult to remove from the circular segment-shaped section of the cylinder pit, since they lie like beads in this section.
- the invention has for its object a device for holding the bent ends of an arcuate carrier, for. B. to create a flexible pressure plate on a cylinder, by means of which the arcuate support can be replaced quickly and its ends can be held free of damage.
- a forme cylinder 1 is provided with an axially parallel hole in the vicinity of its outer surface 2 which has a circular cross section and has an axially parallel hole 3, for. B. provided with a circular segment-shaped cross section.
- the slot 4 is on the side, -. B. right -, with hole 3 in connection.
- the hole 3 can be cylinder-long, but only z. B. have the length of the width of a page-wide printing plate, so be designed as a blind hole.
- the slot 4 receives both ends 7, 8 of a pressure plate 9 in such a way that these ends 7, 8 run parallel to one another and touch with the inside of the surface.
- the outside of a first end 7 lies against a cylinder wall 11 of the slot 4, while a second end 8 of the pressure plate 9 closes laterally with its outside into the hole 3.
- a second end 8 of the pressure plate 9 closes laterally with its outside into the hole 3.
- the hose 14 is filled with a medium, e.g. B. compressed air and is provided at least on one of its two end faces or ends, which are in the immediate vicinity of the end faces of the forme cylinder 1, with a check valve, not shown.
- the check valve can be connected by means of a compressed air source, not shown, so that the hose 14 fills the axially parallel hole 3 and presses into the slot 4 and with a force P the two ends 8, 7 against the left wall 11 of the slot 4, so that these two ends 7, 8 of the pressure plate 9 are held.
- the compressed air escapes from the hose 14, for. B. by a ventilation device, also not shown, for. B. by at least one vent screw, which is arranged at one end of the hose 14.
- a liquid for filling the hose 14 e.g. B. oil, or glycerin, which can be supplied to the hose 14 by means of a supply line via the check valve under pressure.
- This insert strip can be arranged in an axially extending cylinder pit of the forme cylinder 1.
