A plurality of inserts is mounted on the belt for supporting the sheets. Each of the inserts comprises an elongate strip, the strip including an edge integrally formed with a plurality of pointed projections. A widest cross-section of the insert is sized to permit the insert to be inserted laterally into a lateral opening in the belt with the projections thereof lying in the plane of the belt and then rotated 90.degree. to a position wherein the projections extend beyond the plane of the belt to support the sheets. Provided at each end of the strip is a pair of bendable tabs which can be crimped around a wire portion of the belt to anchor the strip to the belt. Since the sheets are supported only by pointed projections, thermography printing can be performed on both sides of the sheets with little risk of the ink being smeared. | ||||||

| 397 | Offset duplicating machine | US916548 | 1978-06-19 | US4228735A | 1980-10-21 | Laurent Doucet |
| In an offset duplicating machine, an implement for marking, such as perforating, slitting, scoring or the like, each printed sheet conveyed through the machine; for transverse marking, a first marking strip is affixed lengthwise on an impression cylinder and a rotatable counter-roller is mounted adjacent and at a skew inclination to the impression cylinder; the counter-roller has an outer surface of hyperboloidal shape which allows the strip to progressively mark the passing sheet. By grooving the counter-roller or by varying the distance separating it from the impression cylinder, additional marking strips may be affixed to the impression cylinder to provide various marking configurations on the printed sheet. | ||||||
| 398 | Method for applying stiffener to computer paper | US660592 | 1976-02-23 | US4060651A | 1977-11-29 | Frederick A. DaMert |
| Stiffeners in the form of spaced, narrow bands or lines of flowable, quick-setting material are applied to one side of a moving paper web to be used as computer paper. The stiffeners are applied either immediately before or during the time the paper web is partially wrapped around a cylindrical drum so that the material will set to a solidified condition while it is on the drum to set up a molecular pattern in each stiffener line, causing the paper web to be inherently biased in one direction. Guide means is provided for directing the paper web onto and off the drum. The material may be applied by applicator guns or wheels as the paper web moves through a rotary printing press and as it moves toward a line hole punch apparatus, perforating means and a fan-folding mechanism. | ||||||
| 399 | Rotary printing press impression cylinder having clamping and sheet gripping devices | US49772374 | 1974-08-15 | US3926118A | 1975-12-16 | PREUSS FRIEDRICH |
| A printing press of the lithographic type having a pair of blanket cylinders and a cooperating impression cylinder. At least one of the blanket cylinders has, adheringly mounted thereon, a perforation strip presenting a line of regularly spaced perforation projections extending to a constant shallow height from the surface of the blanket. The impression cylinder is provided with a resilient, perforation-inducing covering layer for cooperating with the projections so that when the cylinders rotate together a sheet held by the impression cylinder is penetrated with a line of perforations. In the preferred embodiment of the invention the two blanket cylinders cooperating with the impression cylinder each have perforation strips, extending respectively at right angles to one another, and which successively engage the sheet on the impression cylinder, so that intersecting lines of perforations are produced in the sheet. In accordance with one of the aspects of the invention the impression cylinder is formed with a longitudinal gap or groove having a well defined edge and a recess extending continuously thereunder. The resilient covering layer has a mounting bar at one end which is clamped in the recess, with the covering layer being drawn over the edge of the groove in a tight bend. Mounted at the edge of the groove, adjacent the bend, is a gripper pad bar having a cooperating cyclically operated set of grippers for gripping the leading edges of successive paper sheets. The set of grippers and the gripper pad bar are both mounted in such a way as to permit temporary retraction away from the edge of the groove thereby to provide a radial clearance path for easy removal of the mounting bar and its associated covering layer when the mounting bar is unclamped. This permits rapid substitution of a conventional non-resilient impression blanket upon detatchment of the perforation strips to reestablish the normal printing function of the blanket cylinders.
