| 61 | Perforating strip for printing presses | US3554070D | 1968-11-18 | US3554070A | 1971-01-12 | BOYD HARRY S |
| This invention relates to an improved perforating strip for printing presses. More particularly, the invention relates to a device for perforating paper as the paper passes over the impression cylinder of an offset or lithographic press, the device comprising an elongated thin metal strip having a base portion and having upstanding teeth along one edge of the base portion, the teeth being spaced apart from each other and the base portion having notches therein between the teeth so that the base portion is of reduced width at the notches, the notches providing relief of pressure of paper pressing against the teeth and base portion and permitting each of the teeth to flex individually.

| A device for processing substrates improves processing quality during separation or punching of such substrates. The device has a first processing cylinder and a second processing cylinder for treating substrates, and between which the substrate can be inserted. The substrate undergoes processing as it passes through the cylinder nip between the processing cylinders by use of tool parts that are active therein, and which may be chosen from a group composed of cutting tools, punching tools, creasing tools, perforating tools and grooving tools. The first processing cylinder has a sheet holding system and one of the first processing cylinder and the second processing cylinder has a tool carrier for receiving a tool part. An impression cylinder, which is in surface contact with the second processing cylinder, is assigned to the second processing cylinder, on the side thereof that faces away from the first processing cylinder. | ||||||

| It is an object of the present invention to provide a sheet-fed printing press that prevents occurrence of troubles, such as damages of a surface treatment member such as a film for the surface treatment of, for example, a sheet of paper, by a simple structure. A gripping surface of a claw block provided in a cylinder of a treatment section is formed into an inclined surface that comes closer to the rotational axis as it advances downstream in a sheet conveying direction of the cylinder, so as not to have the gripper of the cylinder contacting the treatment means. A gripping surface of a claw block provided in a cylinder most adjacent to the treatment section, of plural cylinders, is formed into an inclined surface that, projects further through an outline of this cylinder as it advances downstream in the sheet conveying direction. A gripping surface of a claw block provided in the cylinder closest to a printing impression cylinder is formed into an inclined surface inclined at an angle smaller than the inclined angle of the gripping surface of the claw block of the cylinder provided in the treatment section. | ||||||
