The tractive elements extend from one drum at one end of the press to a further drum at the other end so that they may be wound onto and unwound from such drums moving the draw-in bar along the web path.

Abstract: In a folder with at least one folding blade cylinder cooperating with a folding jaw cylinder, and with a guide mechanism which is located at each outlet wedge situated after the folding place in the direction of rotation of the respective cylinders cooperating in the folding process, extends over the entire length of the cylinder, and guides the parts of the sheets lying, after the folding place, on the circumferential section of the folding blade cylinder and being taken therefrom in the folding process, a long life of the guide mechanism as well as careful handling of the signatures to receive a cross fold can be guaranteed by the guide mechanism being equipped with a middle part which is so supported that it can turn freely around an axis parallel to the cylinder and has an approximately cylindrical surface, and with stationary connecting parts which join the said middle part laterally and have a surface contour cutting about tangentially into the surface of the middle part.

Abstract: A delivery device comprising at least one conveyor belt defining a conveying plane arranged under a fan wheel to receive products from the fan wheel more especially in the form of an overlapping stream. The device has at least one elongated and raised member that is aligned with the direction of delivery and which slopes downwards from a higher level than the conveying plane on the conveying belt in the direction of delivery and at its front end has an edge that adjoins the conveying plane on the conveying belt side.

Abstract: Sheet-like products coming off a folder are firstly transported some distance before being caused to overlap. In order to slow down the products to cause this to take place and to arrange them in a perfectly regular feed stream without being damaged, the products are engaged by grippers that are moved along a preferably arcuate path on a support in the course of which the products are slowed down by the grippers to the speed of a delivery belt on which the products are then deposited.

Abstract: A gravure printing machine cylinder has a means for mounting wrap-on gravure plates thereon using a tensioner able to be rocked about the shaft of the cylinder and having an outer cylindrical face in keeping with the outline of the cylinder in the printing condition. In order to be certain of a truly cylindrical outline of the wrap-on plate that is to be fixed on the cylinder, while at the same time decreasing the distance through which the plate is pulled when being mounted, the tensioner has a member with a beaked rim that is able to be rocked about an axis parallel to the cylinder axis separately from the tensioner, said beaked rim functioning with a gripping part in taking up and fixing in place the mounting fold or flap of the wrap-on plate.

Abstract: In the case of a device for holding offset or other plates on the plate cylinder of a printing press with two clamping members on the two sides of a well running in the axial direction of the cylinder and each having a gripping part of clamping the hooked ends of the plate and at least one of the members may be rocked about an axis parallel to the axis of turning of the cylinder, the necessary width of the well may be greatly decreased in the clamped condition of the system of one of the clamping members, that is able to be rocked, takes the form of a segment bar having a cross-section that is generally three-sided and segment-like. This bar may be placed next to an outer face of the cylinder body and has an outer face lined up with and continuing the outer face of the cylinder body.

Abstract: In the operation of a multi-color printing press an accurate and at the same time economic control of the inking of the printing plate or the like is made possible by converting the optical frequencies of light reflectance from inking zones (i.e. the zones controlled by the different fountain keys or the like) of the products printed on the press into representative acoustic frequencies which may be processed by electronic signal processing circuitry.The conversion of the light reflectance (diffusely reflected light from the printed image) into acoustic frequencies is undertaken by a light-pressure transducer with a microphone whose electrical output signal goes to a variable frequency filter means with a scan function such that narrow frequency sub-ranges are produced that are processed spectrally in keeping with the intensity thereof.

Abstract: In a staple wire supply system for use in connection with printing machinery or the like and of the sort having a fixed wire guide pipe past whose outlet end a knife is moved for cutting the wire down to the size needed for stapling, the time needed for the operation of changing over to a new reel of wire when one reel has run out may be greatly cut down by so designing the system that two reels may be supported thereon at a time and having a unit for running one wire from one such reel to the guide pipe and guiding the other wire into a ready or waiting position. Between this unit and the guide pipe there are two wire driving parts, such as pinch rollers acting on opposite sides of a capstan, which may be changed over in direction and may be used for moving wire from the two reels in oposite directions at the time of reel changing.

One band guidance surrounding the rear peripheral segment transports web segments from which the inner portion is assembled to the collecting cylinder, while the other band guidance which surrounds the front peripheral segment delivers web segments forming a cover to the collecting cylinder. The collecting cylinder is provided with holding members which grip the leading edges of the web segments being set thereon, the holding members being activated in the region of the front peripheral segment. The holding members being inactivated following the completed collection process after passing the folding flap cylinder associated with the collecting cylinder.

Abstract: In connection with a unit for parallelizing a chain of overlapping printed products such as signatures (that is to say causing the leading edges to be parallel), delivered by way of a fan wheel onto a delivery belt thereunder, the purpose of the invention is to make for trouble-free operation, to see that the signatures are completely regularly placed, and to make upkeep work on the unit simple. For this purpose, the unit has at least one driver which is moved along at a higher speed than the signatures so as to come up against the trailing edge of each signature as its leading edge comes onto the delivery belt. The driver is moved along a line of motion in such a way that at least part of such motion is directed out of the transport plane of the delivery belt. The driver may be a simple kicking edge of a part fixed to a driver support.

Abstract: The invention has to do with conveying systems for folded products coming from a folder and each made up of sheets which are overlapped so that their unoverlapped edges are sticking out sideways. For pulling the overlapped sheets out sideways and separating them, the apparatus has two gripping means moving along the sides of the system, each gripping means having a gripping gap for taking up said edges. One gripping means is placed at an angle to the direction of conveying for pulling the sheets out to the side. The gripping means are made up of belts or pulleys running at an equal speed and with a gap between them for the edges. One useful effect of the apparatus is that it is not necessary to keep to any fixed spacing between the products in their direction of transport.

Abstract: In connection with an apparatus for putting paste on a moving printed paper web in strips at a right angle to the direction of motion of the web by moving the web between a pasting cylinder and a web support part on the other side of the web, one purpose of the invention is to make certain that the strips of paste may be put on at a high speed and to have such a design that the upkeep work on the apparatus is simple and may be done quickly. To make this possible, the pasting cylinder is made up of cylinder body and a paster roll placed within it so that a limited area of its outer face is uncovered by an axial slot in the outer face of the body. The paster roll has one or more wells stretching along it that are topped up with paste at a point within the pasting cylinder body, while the parts of the outer face of the roll between the wells are stripped and kept clear of the paste.

Abstract: In a strand length for conveying and slowing down folded products beteen two consecutive stations of a folding apparatus, particularly between a folding cylinder and a folding sword or delivery station, with a minimum of two consecutive stand sections driven at opposingly stepped speeds, each strand section including an upper and lower belt set having a plurality of parallel belts in each set and a minimum of one forward belt roller in the conveying direction and one rear belt roller in the conveying direction, of which at least one of the front belt rollers of the faster moving rear strand section in the conveying direction and at least one of the rear belt rollers of the slower moving front strand section in the conveying direction are adjustable for height, and the belts of each of said belt sets are spaced apart and staggered by at least a belt width so that said rear and front strand sections may be dovetailed into each other.

Abstract: In a printing press such as a rotogravure press having cylinder which frequently has to be changed and which is joined up with a driving shaft by way of a clutch, more rational changing of the cylinder is made possible by designing the clutch in the form of a housing, joined with the driving shaft, and of a pin (coaxially fixed to the end of the cylinder) within the housing, that has a collet-like bush within it which takes up the pin and may be caused to undergo contraction and expansion for gripping and freeing the pin within it. To this end there is a stack of frustoconical washers placed on the bush. This stack may be acted upon by a spring unit in an axial direction while the opposite end of the stack is supported. For freeing the stack from the force of the spring unit and so letting expansion of the bush take place, the spring unit may be acted upon by a piston and pushed clear of the stack. On the opposite side of the piston there is a piston working space into which driving fluid may be run.

Abstract: A cylinder for machines processing running lengths of material is supported at its ends by bearing frames which may be moved for moving the cylinder, the cylinder having a pipe-like or tube-like outer casing which is supported by self-aligning bearings and has within it a core which is not turned and has an outer diameter smaller than the inner diameter of the casing, the casing being supported on the core by at least one support bearing which is symmetrical with respect to the middle of the casing and coaxial thereto. To give the casing a desired line of bending, to be in harmony with the cylinder with which it is used (on the other side of the running length of material) without being changed by moving the cylinder towards and away from the other cylinder, the pipe-like casing is supported in self-aligning bearings at its ends, separately from the core within it, on the end bearing frames.

Abstract: For producing quality work on a printing machine using a hard printing plate and high viscosity printing ink taken up by a fountain roller running in an ink fountain and transported by the fountain roller to an ink drum running against at least one form roller for inking the plate, while nevertheless keeping the inking system design simple, the inking unit has a single form roller having a diameter equal to that of the working diameter of the plate and designed to be run at the same surface speed as the plate: the drum for inking the form roller has a screen on its outer face made up of ink takeup pockets separated by lands, the ink drum having a smaller diameter than the form roller and being turned by a driving system of the press. The outer face of the ink drum with the screen is stripped by a stripping unit, such as doctor plate, running on and clearing the lands between the ink takeup pocket. Furthermore the fountain roller is run with a speed different to that of the screened ink drum.

Abstract: A switch system for clearing spoiled items from an overlapped stream of paper products such as signatures has a three-flight conveyor belt transporting system whose middle flight may be rocked bodily so that its downstream belt support roll, functioning as a switch roll, is moved between an upper position in which it is leveled up with the next flight, and a lowered position for sending the stream, when made up of spoiled items, downwards under the next flight to a separate delivery. The side face of the upstream belt roll of this same next flight is covered by a cover for neatly separating the stream and switching it over into the downward parts under this next flight. Over the switch a backer roll is placed so as to have its weight supported on the stream of products (in turn supported by the switch roll). In this way the products are well gripped and controlled.

Abstract: For the purpose of helping in the making of a second lengthways fold in a web of paper in a folder having a folder blade for producing this fold, the paper is firstly scored at the desired fold position in the long direction by a sharp-edged wheel pushing the paper against a turning back-up part, which is let into the face of one of the nipper or guiding rolls of the folder. The wheel with the sharp edge is placed on the other, opposite roll between separate roll parts or wheels thereon gripping the web against the other roll.
