and 3, according to these ?gures, a copying machine

with the present invention to utilize copying machines

wet developing station.
The copy ?nished in the copy unit 1 in accordance
with the present invention may, on the one hand, repre
sent a ?nished product and, on the other hand, represent
an intermediate product wherein the copy from the
copying machine 1 is fed to an offset printing machine
generally designated by the reference numeral 13 dis
posed downstream of the copying machine 1, whereby
the copy from the copying machine 1 forms the master
copy for the offset printing machine 13.
The path travelled by the copy produced by the
copying machine 1 is controlled by a reversible switch
14 which, in one position, connects a conveyor path
with two additional pairs of transporting rolls 15, 16 to
the outlet of the copier 1, leading to a receptacle or
depository 17 arranged at the top side of the housing of
the offset printing machine 13. The switch 14, in a sec

of transporting rolls 18 associated with an etching unit
19. The unit 19 includes an outlet followed by a plate
cylinder 20 of the offset printing machine 13.

After the offset printing operation, the master copies
are removed from the plate cylinder and fed by way of
a pair of transporting rolls 33 to a used master copy

or depository 34 and the paper-feeding mechanism 26
may be arranged in the copying apparatus so that they
can be pulled out of a side wall of the entire apparatus
directed to a receptacle or depository 31.
Feeding mechanism 26, provided with an elevator
table, is arranged beside the rubber blanket cylinder 24
and impression cylinder 44 with a storage compartment
34 being arranged above the feeding mechanism 26,
in the manner of a drawer in order to remove the used

form of a compact cubic shape. The housing 35 may
accommodate; in a manner not illustrated in detail, the
electrical circuits and air supply devices such as fans or
the like. By virtue of the construction illustrated in FIG.
1, all of the parts of the copying apparatus, which are
preferably combined into individual modules, are indi

During the reproduction of a multi-page original at a
number justifying theuse of the offset printing machine
13 or 39, it is advantageous ?rst to produce all master
copies which are then placed into a type of buffer sta
tion or storage means, whereby, automatically, the last
produced master copy is fed as the ?rst master copy to
the offset‘ printing machine 13 or 39 so that the last page
of the original is duplicated ?rst. This is advantageous
since, after the entire procedure has been ?nished, the
resulting stack of printed copies is arranged in the cor
10
expedient, to provide stacks or cassettes having differ
ing sheet formats in order to provide a clamping action
for the plate cylinder of the printing machine 13 or 39.
In this latter situation, the machine serving for the print
ing operation must be controlled so that, prior to the
start of the copying by the printing machine, the correct
stack or correct cassette is switched or placed in its
correct operative position. By the use of a similar prin
ciple, it is also possible to employ a copier which copies
on normal paper, with such copier being equipped with
a second stack, second cassette or a second storage reel
from which the material is withdrawn, which is utilized
for the production of master copies.
