Definitions
- the invention relates to a forme cylinder slot-shaped pressure plate entry according to The preamble of claims 1 and 2.
- DE 42 03 550 A1 is a feed device for compressed air on a rotatable cylinder Printing machine known via a cylinder journal become.
- With the axially extending bores are radial Holes in connection, which are in sockets or Openings to the compressed air outlet open.
- Forme cylinder for offset web rotary printing presses with slot-shaped pressure plate insertion have been known for a long time.
- the beginning of the printing plate is included one pointed and the pressure plate end with one obtuse opening angle.
- the first Pressure plate end With the acute opening angle in one - seen in cross section - acute-angled hook-in edge hooked in, the length of the hooking edge at least corresponds to the printing plate width.
- the hanging edge formed from hook radius with inclined Contact surface for the start of the printing plate, forms together with one lying parallel to it Contact surface for the pressure plate end and the slit-shaped base of an abutting surface Pressure plate end entry.
- the distance of yourself opposite contact surfaces is slightly larger than twice the plate thickness.
- EP 05 35 502 A2 and CH-PS 518 176 describe each form cylinder with slot-shaped insertion for folded ends of a pressure plate.
- EP 02 15 645 A2 describes a forme cylinder to which a pressure plate is attached by means of negative pressure.
- valves are used with the pressure plate interacting plunger actuated.
- the invention is based on the object a device on a forme cylinder To create rotary printing press with the one folded end of a pressure plate without the aid of tools in a simple way from one Insertion slot for receiving pressure plate bends at least so far in the slot that the Printing plate end conveniently by an operator or Vending machines can be pulled out of the slot and thus the affected end of the pressure plate from the cylinder circumference can be lifted off.
- An embodiment is based on a figure as Solution example described without referring to this To limit embodiment.
- a pressure plate with two bevelled ends e.g. B. placed an offset printing plate.
- the fold has an acute-angled, the fold for the end of the pressure plate obtuse-angled opening angle beta. Both ends come into an insertion gap with the printing plate in place 2 to lie in the forme cylinder 1.
- Such one Insertion gap 2 is well known and was in the introduction to the description is described in detail, see above that for simplification reasons a repeat is waived.
- At least the pressure plate end with the Bending with an obtuse angle Beta - im following briefly called “obtuse-angled bend" - is pressed into an insertion gap 2 and holds there until the pressure plate is to be replaced.
- This lifting device 4 can consist of various means. So a lifting and lowering lifting bar can be provided. However, a plurality of nozzles 6 can also be provided for the discharge of compressed air.
- the controlled compressed air occurs e.g. B. from all the nozzles 6 at the same time and lifts the pressure plate end in the vicinity parallel to the folding line of the folded pressure plate end to the extent that at least the side edges can then be gripped.
- the end of the pressure plate is lifted up so far that the bend of the end of the pressure plate has completely left the insertion gap 2.
- the nozzles 6, which end with the lateral surface of the forme cylinder 1, ie do not protrude beyond them, are fed with compressed air via first radial bores 7.
- the bores 7 begin in an axially extending storage chamber 8 for the compressed air, which is connected to an axial bore 11 by means of several second radial bores 9. This axial bore 11 is connected to a radial bore, not shown, in a shaft journal.
- the clocked supply of compressed air via z. B. a device according to DE 42 03 550 A1 from a compressed air source.
