Die verschiedenen Formen C² sitzen auf dem intermittirend rotirenden polygonalen Cylinder C. Diesem gegenüber befindet sich der gleichgeformte Cylinder C¹, auf welchem die den Formen entsprechenden Tiegel C³ sitzen. Jeder dieser Cylinder lagert in Armen D D und D¹ Z)¹, welche um die Wellen EE¹ schwingen können und ihre schwingende Bewegung durch die auf beiden Seiten der Maschine befindlichen Scheiben B erhalten. Zu diesem Zweck sind sie mit den Rollen d d versehen,, welche in den unrunden Führungsrinnen b P geführt werden. Die Form dieser aus Fig. 4 ersichtlichen Rinnen nöthigt die Arme D und D¹ bezw. die an diesen siteenden Cylinder Cund C¹, sich bei jeder Umdrehung der Scheiben B¹ ein mal einander zu nähern und ein'mal von einander zu entfernen. Indem sich die Cylinder C und C¹ einander nähern, wird die zunächst liegende Form C² gegen die gegenüberliegenden Tiegel C³ angeprefst, und die auf diese Form aufgetragene Farbe auf das zwischen beiden von dem Rähmchen JI gehaltene Papier aufgedruckt. Nach erfolgtem Druck entfernen sich die Cylinder C C¹ von einander und werden dabei um eine Form bezw. einen Tiegel weiter gedreht. Dies geschieht mit Hülfe der Mitnehmerscheiben U\ welche ebenfalls auf den Armen D und D^l sitzen und ihre continuirliche rotirende Bewegung durch die Kegelräder VV, die Wellen V¹ V¹ und die Kegelräder W W von den Wellen E E¹ aus erhalten. An den Scheiben U¹ sitzt ein Mitnehmer U, welcher nach einander in die seitlichen Nuthen C¹ des Form- bezw. Tiegelcylinders eingreift und den Cylinder dadurch den Theil einer Umdrehung machen läfst. Da die Nuthen Cⁱ, wenn sie sich in einer gewissen Stellung zu den Scheiben U"¹ befinden, concentrisch mit diesen laufen, so bewegt sich der Mitnehmer U eine Strecke weit in diesen Nuthen fort "und hält den Cylinder C bezw. C¹, ohne ihn zu drehen, so lange in seiner jeweiligen Stellung fest.The various forms C ² sit on the intermittently rotating polygonal cylinder C. Opposite this is the identically shaped cylinder C ¹ , on which the crucibles C ³ corresponding to the forms sit. Each of these cylinders is supported in arms DD and D ¹ Z) ¹ , which can swing around shafts EE ¹ and receive their swinging motion from disks B on both sides of the machine. For this purpose, they are provided with the rollers dd , which are guided in the non-circular guide channels b P. The shape of these grooves shown in FIG. 4 necessitates the arms D and D ¹ respectively. The cylinders C and C ¹ ending at this site , approach each other once with each revolution of the disks B ¹ and move away from each other once. As the cylinders C and C ¹ approach each other, the initially lying mold C ^{2 is} pressed against the opposing crucibles C ³ , and the color applied to this mold is printed on the paper held between the two by the frame JI. After printing, the cylinder CC ¹ move away from each other and are respectively around a shape. turned one crucible further. This is done with the aid of the drive plates U \, which also sit on the arms D and D ¹ and receive their continuous rotating movement through the bevel gears VV, the shafts V ¹ V ¹ and the bevel gears WW from the shafts EE ¹ . On the disks U ¹ sits a driver U, which one after the other into the lateral grooves C ^{1 of} the form or. The crucible cylinder engages and thereby makes the cylinder make part of a revolution. Since the grooves C ⁱ , when they are in a certain position relative to the disks U " ¹ , run concentrically with them, the driver U moves a distance in these grooves" and holds the cylinder C respectively. C ¹ so long in its respective position without turning it.

Die Formen C² erhalten successive ihre Farbe von der Farbvorrichtung S, welche mit so vielen Farbbehältern mit Vertheilungs - bezw. Auftragwalzen t versehen ist, als Formen vorhanden sind. An der den Formen gegenüberliegenden Partie befinden sich die geraden Schienen S¹, auf welchen die Auftragwalzen über die jeweils gegenüberliegende Form hinweggeführt werden, um dieselbe mit der entsprechenden Farbe zu versehen. Sämmtliche Farbwalzen t mit ihren Farbbehältern sitzen auf der gemeinsamen Welle T, welche durch das Schiebrad t¹ und den Schiebkegel T¹ eine der intermittirenden Rotation des Formencylinders C entsprechende intermittirende Drehung erhält. Zu diesem Zweck sitzt der Schiebkegel an einer Stange, an deren unterem Ende die Rolle T³ sitzt. Diese Rolle wird durch eine Feder gegen die mit der Welle E rotirende, unrunde Scheibe T* angedrückt und erhält von dieser eine auf- und abgehende Bewegung. Schlitze s und Bolzen s^l The forms C ² receive their color successively from the color device S, which with so many paint containers with distribution - respectively. Application rollers t is provided as forms are available. On the part opposite the molds are the straight rails S ¹ , on which the applicator rollers are guided over the respective opposite mold in order to provide the same with the corresponding color. All of the ink rollers t with their ink containers sit on the common shaft T, which receives an intermittent rotation corresponding to the intermittent rotation of the forme cylinder C by the feed wheel t ¹ and the sliding cone T ^1. For this purpose, the sliding cone sits on a rod, at the lower end of which the roller T ³ sits. This roller is pressed by a spring against the non-circular disk T * rotating with the shaft E and receives from this an up and down movement. Slots s and bolts s ^l

Claims

allow adjustment of the straight guide 51 of the inking rollers. The paper K unwinds from the roller K, passes between the rollers LL, is advanced by the disks MM, which can be adjusted by slots and bolts mvi, by a piece corresponding to the length of the printing sheet each time after the cylinders C ϋλ have made a complete revolution kept in register by the frame JI during the printing of the different colors. When printed, it is fed from the rolls NN to the knife P and cut there. The cut sheet falls on delivery Q and is placed by this on the table R '. The frame consists of two plates / which are provided with cutouts I1 corresponding to the shapes and which are placed against the paper to be printed from both sides by the frame JJ. The plates / / are, in order not to present any obstacles to the paper as it passes, slightly outwardly curved above and below, as can be seen from FIG. The knife P is moved by a crank P ', the rod P2 and the non-circular disk R sitting on the shaft B. The same non-circular disk R also moves the boom Q through the intermediary of the rod Q1. The shafts B E E1 K1 and T are mounted in the frame A. On the shaft B sit the pulleys B "Bs, and from this shaft, by means of the gears e e1 el and e3, the shafts E and E 'get their rotating motion. P ATENT -An s ρ rüch.e:

1. On multi-color printing machines, the polygonal cylinder C on which the forms C ² sit and. which is rotated intermittently and alternately guided on the one hand against the paper to be printed and on the other hand against the inking device, while the paper to be printed remains stationary during a whole revolution of the cylinder and is printed one after the other with the colors of the different shapes.

2. The same device in connection with the oscillating arm D , which is moved back and forth by a disc B provided with an eccentric guide and brings the cylinder C attached to it into contact with the paper to be printed and the other time with the inking device.
