Abstract: A folder has at least two transverse paper cutters, each with folding blades for use with a fold jaw cylinder for sheeting and folding paper web coming from a printing press and forwarding the sheets produced to a delivery station.The one or the other transverse cutter (as put into operation on makeready) is used for producing sheet sizes answering to the full or half of the plate cylinder circumference of the printing press.The fold jaw cylinder has tool take-up or fixing positions spaced about its circumference with a spacing equal to half the smaller sheet size to be processed. The fold jaw cylinder is designed to have fixed thereon fold jaws with a spacing therebetween equal to the spacing between the folding blades of the one or the other cutter used at the time and to have fixed thereon scissor or shear cutting knives, running out past its circumference radially and spaced to the back of the jaws (in the direction of running) by half the jaw-to-jaw distance.

Abstract: In order to prevent waste and to improve the operating safety and easy operation of a device for making printed matter with changing prints or for adding further printing to a complete print, further printing units are provided associated with a printing unit having a common counterpressurer cylinder which is constantly connected with the main drive of the machine. The printing units are each provided with a normally passive acceleration motor and after completing the acceleration process are coupled (or decoupled) with the main drive of the machine by means of a coupling, having a movable coupling element which is operatively mounted independently of the print unit gear train and which is actuated by an adjustment device.

Abstract: A folding apparatus for rotary roller printing presses, having at least one collecting or crosswise folder, positioned behind which there is at least one sword folder composed of a folding sword interacting with a pair of folding cylinders, the folded material being conveyed to the sword folder via a belt guide having upper and lower belts and, in the region of the folding sword, passing positioned limit stops for the folded material. The belt guide has at least two strands positioned one behind the other and being driven at opposingly stepped speeds, with the faster-running strand on the collecting or crosswise folder side, having a run-out groove opening wedge-shapedly, beyond which least one locating stop moving at the speed of the slower-running strand, on the sword folder side, is positioned, its path at least partly overlapping with the feeding-in region of the equally fast belt guide strand.

Abstract: A device for deflecting a product stream consisting, in particular, of folded sheet products, from a first to at least one following longitudinal conveying device which are laterally displaced apart is provided. The distance between the first and second longitudinal conveying device is bridged by a further longitudinal conveying device which is inclined to an extent corresponding to the lateral displacement of the first and second longitudinal conveying device. The further longitudinal conveying device preferably includes two parallel, uniformly-driven conveying elements positioned adjacent to one another.

Abstract: A device is provided for the rapid clamping of flexible printing plates on the printing cylinder of rotary printing presses which includes a support bar mounted within and adjacent to the front side of a cylinder groove to which the forward end of plate is clamped by means of clamping springs and a clamping arm disposed opposite of the support bar, which is pivotably mounted within and adjacent to the rear side of the groove and has a plate attachment arm to which the rear end of the plate is clamped. The clamping arm is actuated by means of pressure springs in the clamping direction and in the counter direction by adjustment means so that the plate ends may be clamped independently from one another as well as independently of the plate thickness so as to prevent damage to the plates during the clamping operation and an easy servicing.

Abstract: A stapling machine is provided of the type which includes at least one stapling cylinder having a wire transport, a shaped disk which for the formation of the staples bites into a peripheral recess provided in the stapling cylinder, and a fixed staple guide which, with reference to the rotational direction of the stapling cylinder, is positioned after the shaped disk, projects into the peripheral recess and is underrun by the finished staple. The stapling machine is characterized in that the staple guide has, in the area of its surface which is underrun by the back of the staple, a post-bending edge which bites deeper into the recess in the stapling cylinder than does the outer periphery of the shaped disk.

Abstract: A device for clamping flexible printing plates onto the plate cylinder of rotary printing presses, wherein the plate cylinder has a concentric groove formed in its surface, the groove walls extending at an acute angle into the surface of the plate cylinder to define a pair of hook-like edges at the groove opening for receiving the correspondingly hook-like bent ends of the printing plate. A spindle is pivotably disposed in the groove having an axis concentric with the groove. At least one flange spring is supported on a first side of the spindle which faces a first hook-like wall edge. A clamping element is formed at one the end of the spring for engaging the front end of the printing plate against one of the hook-like groove edges. A bar disposed on the opposite side of the spindle axis and mounted to the spindle, the bar extending into the plate cylinder surface for receiving the hook-like bent rear end of the printing plate.

Abstract: Folding device for roller rotating printing presses for folding a prefolded pack of sheets which is fed by a pair of endless conveyor belts underneath a folding knife in parallel direction of its feeding movement wherein at the arriving end and on both sides of the folding knife, a finger is moved into the feeding path of the pack of sheets so as to engage an advancing front edge of the pack of sheets. The finger is forcibly moved into rotation by a shaft which runs laterally beneath the endless conveyor belts whereby the rotation moves the finger in a working cycle above the lower plane of the endless conveyor belts and the finger runs slowly in direction of the feeding motion, but more slowly than the same.

Abstract: The invention is concerned with a device for slowing down a fed printing specimen as it is fed to the paddle wheel, and includes a pair of rollers, one of which is adjustable relative to the other to provide for an adjustable wedge portion therebetween which includes means to slow the speed of the fed printing specimen down as it is fed to the paddle wheel.

Abstract: A cylinder for clamping printing plates for photogravure printing wherein the cylinder has a longitudinal bore comprising at least one clamping spindle with a surface for receiving the printing plate ends said at least the clamping spindle runs on the radius of the surface of the cylinder, wherein in the clamping and closing position, the cylinder bore is closed. The clamping spindle is flattened on the inside and loosely supports a continuous cylindrical cup which is positioned in the axis radial in the clamped and locked position of the clamping spindle. There is a tension spring and ball disposed in a lateral bore of the clamping spindle for supporting the spindle with respect to the cylinder bore wall at the side which is opposite to the advancing side of the cylinder.

Abstract: Positioned adjacent to the delivery end of a device for folding sheets delivered from a printing press is a sheet pick up device to intercept a sheet for test purposes. The mechanism to intercept the sheet includes a receiving roller carrying a guide belt which is moved into the delivery path and then transfers the sheet to a second guide belt for holding the test sheet between the two guide belts for delivery to a special delivery means where the sheet can be inspected. The roller is supported on a movable arm which is synchronized with the delivery belt of the folding apparatus, and the guide belts are arranged to move at a speed faster than the delivery belts. The removal of a sheet for test purposes does not interfere with the delivery of the other sheets and operations do not have to be stopped to test a sheet.
