Um eine Greiferspitze zu schaffen, bei der sich Papierabrieb, Schmutz oder dergleichen nicht mehr festsetzen kann, weist deren profilierte Haltefläche am vorderen Teil eine einzige mit dem Bogen (6) in Berührung kommende wulstartige Erhebung (4) mit einem Wulstradius (R) von 0,4 - 1,0 mm auf, die parallel zur Vorderkante des Bogens (6) verläuft und mit einem Hartstoff (8) beschichtet ist.

The invention relates to a silkscreen printer having a cylindrically curved printing table intended for applying print to print material. The printer further comprises a stencil which is stretched in a stencil frame arranged for reciprocating movement in response to reciprocating of the printing table (2), and also a squeegee device which is intended to press the stencil against the printing table and therewith transfer print onto print material located between the printing table and the stencil. The printer further comprises a gripper (8) which co-acts with the printing table (2) and which is intended to grip firmly the forward end portion (3a) of the print material (3), as seen in the direction of movement, during at least a part of the printing sequence. The gripper (8) is mounted in the printing table (2) for pivotal movement in the direction of the longitudinal curved extension of the printing table. When occupying a registered position the gripper (8) is pressed against a stop means (13) by means of a spring device (16) such as to register the gripper in relation to the printer chassis (10), this registration being effected without taking into account the stop position of the stencil frame and printing table (2). It is suggested that Figure 3 is published together with the abstract.

There is provided sheet printing apparatus (l) having at least one printing station (4) for sheet printing, sheet transfer means (7, 8) for conveying printed sheets (3), and radiation curing means (ll) arranged to direct curing radiation onto sheets conveyed by said sheet transfer means, said sheet transfer means comprising a sheet gripper means (7) whose length extends tranversely across the sheet feed direction of the sheet transfer means, wherein said gripper means has attached thereto and spaced therefrom a shielding plate (l3) extending along at least part of the length of said gripping means, said shielding plate having as the surface remote from the gripper means a radiation reflecting polished surface which serves to shadow said gripper means from directed radiation from said radiation curing means. In the apparatus of the invention the shielding plate (l3) serves to reduce overheating and heat damage resulting from the exposure of the sheet gripper means to ink-curing radiation. In a particularly preferred embodiment, the shielding plate is provided on its inner surface with fins or vanes (20) which serve to direct heated air towards the sides of the printing apparatus thus particularly assisting the avoidance of component overheating.

Zur Glättung der Vorderkante eines auf dem Anlage blech eines Bogenanlegers für eine Druckmaschine ist oberhalb des Anlegebleches ein auf- und abbewegbarer Balken vorgesehen. Vor dem Ergreifen der Vorderkante des Bogens wird der Balken in Richtung Anlegeblech bzw. in Richtung des auf diesem liegenden Bogens abgesenkt, wo durch Welligkeiten aus der Bogenvorderkante beseitigt werden, so daß dieser im planen Zustand von den Vorgrei fern erfaßt und korrekt in die Maschine eingeführt werden kann. Um den Balken möglichst nahe an die Bogenvorder kante des Anlagebleches positionieren zu können, weist dieser Aussparungen an den Stellen auf, an denen die Greifer und Vordermarken angeordnet sind.

The invention relates to a machine for producing three-dimensional screen-printed articles, comprising a printing bench with a printing screen by means of which at least one printing surface can be printed multiple times, wherein after each printing operation the distance of the screen printing plate is increased by an amount corresponding to the thickness of application of the previous printing operation.

The invention relates to a gripper system (100) for a cylinder (3) of a sheet-fed printing press (1) which guides sheets and which is used to detect printed sheets. Said system comprises a gripping shaft (9) and grippers (8) which are arranged on the gripper shaft (9) and which, during a synchronised normal operation, can be introduced into a cylinder channel of a cylinder (3) which guides the sheet, by means of a pivoting movement of gripper shaft (9), such that the gripper (8) is arranged completely in the cylinder contour after pivoting. According to the invention, the gripper system (100) can be displaced in a radial manner during a cylinder phase displacement such that the grippers (8) of the gripper system (100) enter into a recess and strike an elastically mounted gripper strike bar (10) which enables the gripper (8) to be struck during the radial displacement of the gripper system (100).
