摘要： A drive mechanism especially useful in assemblage with a harmonic drive transmission for providing a desired rotational input to the wave generator of the harmonic drive transmission, and allows for a wide speed range selection while minimizing component wear, instability, and heat generation problems. Such a harmonic drive assembly is particularly useful in powering a controlled infeed or chill stand in a printing press and permits the precise adjustment of the tension of the continuous paper web moving through such a press. The drive mechanism supplies rotational movement from the input shaft of the harmonic drive transmission to the wave generator tuner shaft and includes pulley means operatively coupled to the input shaft, an arm assembly mounted for pivotal movement about the tuner shaft, and a positioning mechanism for precisely pivoting the arm assembly as desired. The arm assembly includes a variable sheave pulley operatively interconnected with the pulley means and tuner shaft, such that pivoting the arm assembly changes the pitch diameter of the variable sheave pulley and effects a corresponding change in the rotational velocity of the wave generator tuner shaft.

摘要： An offset printing press is provided with a novel dual form planetary inker having improved printing characteristics. In use, a plate cylinder rotates to initially contact an ink/water form roller and subsequently contact a second form roller which is devoted exclusively to ink. The ink form roller is operable to insure that voids caused by lint, dust and other debris in the ink train are covered by the second form roller; additionally, the ink form roller provides a second working nip through which a second layer of ink is averaged with the previously deposited ink layer, such that ghosting is substantially eliminated. Both of the form rollers as well as numerous distributor rollers are rotatably carried by a shiftable frame which is pivotally interconnected with a support that carries the plate cylinder. The frame is shiftable from a first position wherein the forms are in rolling engagement with the plate cylinder and a second position wherein both of the forms are spaced from the plate cylinder; however, as the frame is lowered toward its first or working position, the ink/water form is disposed to contact the plate cylinder before the ink form, such that the plate is effectively dampened before ink is applied thereto. In particularly preferred forms, the planetary inker engages the plate cylinder on only two lines of contact, such that any one of a number of various plate cylinder diameters may be utilized.
摘要翻译：一种胶版印刷机具有改进的印刷特性的新型双面行星式油墨机。在使用中，印版滚筒旋转以最初接触墨/水成型辊，并随后接触专用于墨水的第二成型辊。油墨成型辊可操作以确保由油墨列中的棉绒，灰尘和其他碎屑引起的空隙被第二成型辊覆盖; 此外，油墨成型辊提供第二工作辊隙，通过该第二工作辊隙，第二层油墨与先前沉积的油墨层平均，使得基本上消除重影。两个成型辊以及多个分配辊可转动地由可移动的框架承载，该可移动框架与承载印版滚筒的支撑件枢转地互连。框架可以从形状与印版滚筒滚动接合的第一位置和第二位置移动，其中两种形式与印版滚筒间隔开; 然而，当框架朝向其第一或工作位置降低时，油墨/水形式设置成在油墨形式之前接触印版滚筒，使得在将油墨施加到其之前该板被有效地衰减。在特别优选的形式中，行星式墨水器仅在两个接触线上接合印版滚筒，使得可以利用多种不同印版滚筒直径中的任何一种。

摘要： A punch ring apparatus particularly useful in a printing operating involving web fed paper is provided which is easily adapted for punching file holes, line holes, or a wide variety of hole patterns in the moving paper web, thereby substantially reducing makeready times and associated costs. The punch ring hereof preferably includes a plurality of radially-oriented, spaced-apart punches mounted in the punch ring and radially shiftable between an outermost punch position and a retracted position, with the punches being spring biased into the retracted position. The punch ring preferably includes an annular concentric groove in an axial face thereof, with the proximal ends of the punches extending into the groove when the punches are in the retracted position. One or more annular camming rings are received in the groove and configured such that axial rotation of a camming ring will outwardly shift one or more of the punches into the punch position to produce the desired hole punch pattern. Complementally, the die ring of the present invention is configured for operation with any of the hole punch patterns selectable on the punch ring. Thus, the operator can quickly and easily reconfigure the punch ring apparatus hereof for a different hole punch pattern in a minimum amount of makeready time.

摘要： A bender for plastic printing plates locates the line of fold from the leading edge of the plate by providing positioning means adjacent the die surface. The printing plate is placed on a flat base and adjusted to engage the positioning means, the latter in alignment relative to the die. Next, a guide means lifts an edge segment of the plate into a position for engagement by a channel carried by the die. As the die swingably moves through an arc, the edge segment is reversely folded back and into contact with an adjacent area of the sheet while forming a crease sufficient to overcome a substantial part of the memory of the sheet along the line of fold. Consequently, plate image will be precisely parallel to the line of fold, thereby minimizing setup time. Also, plates of various lengths may be bent without adjusting the bender.
摘要翻译：用于塑料印刷板的弯曲机通过邻近模具表面的定位装置从板的前缘定位折叠线。印版被放置在平坦的基座上并被调节以使定位装置相对于定位装置接合，定位装置相对于模具对齐。接下来，引导装置将板的边缘部分提升到由模具承载的通道接合的位置。当模具可摆动地移动通过电弧时，边缘部分被反向折叠并与片材的相邻区域接触，同时形成足以克服沿折叠线的片材的大部分存储器的折痕。因此，平板图像将精确地平行于折叠线，从而最小化建立时间。而且，各种长度的板可以弯曲而不调整弯曲。

摘要： A method and apparatus for controlling the amount of ink transferred to the ink train in a printing press, which reduces press makeready and precisely regulates the ink transfer amount regardless of press speed. The control apparatus includes a fountain roller in operable contact with an ink supply, and a ductor roller mounted for shiftable movement between the ink train and the fountain roller. A sensor provides a signal representative of the interval of rotational movement of the fountain roller while the ductor roller is in contact with the fountain roller and thereby made available for ink transferring contact therewith. This interval is indicative of the amount of ink transferred from the fountain roller to the ductor roller for deposit to the ink train. Further, the control apparatus includes a processor control assembly which receives signals from the sensor and is operable for receiving an instruction input from the press operator indicative of the desired amount of ink transfer. The processor is programmed to correlate the operating instruction input and signal such that when a programmed relationship exists therebetween, the processor initiates shifting of the ductor roller out of contact with the fountain roller.
摘要翻译：一种用于控制在印刷机中传送到油墨列的油墨量的方法和装置，其减少了印刷机准确性，并且无论压制速度如何，均精确地调节墨水传送量。控制装置包括与墨水供应装置可操作地接触的供墨辊，以及安装用于在墨水列和墨斗辊之间移动的导辊。传感器提供表示墨斗辊的旋转运动的间隔的信号，同时导辊与墨斗辊接触，从而可用于与墨转印接触。该间隔表示从供墨辊传送到用于沉积到油墨列的导辊的油墨量。此外，控制装置包括处理器控制组件，其接收来自传感器的信号，并且可操作用于接收来自印刷机操作者的指示输入所需量的墨水传送的指令。处理器被编程为使操作指令输入和信号相关联，使得当它们之间存在编程的关系时，处理器启动导辊的移位与供墨辊不接触。

摘要： An ejection-type inking assembly for use in printing presses is provided which gives precise, readily alterable ink application to an inking roll train and eliminates conventional ink fountains and associated adjustable ink keys. The inking assembly preferably includes a shuttle-mounted reciprocal inking unit having an ink ejector nozzle, a supply of ink and a feed pump for pressurizing successive charges of high viscosity ink and delivering the charges at a constant flow rate to the nozzle. The preferred pump is a twin screw, counter rotating positive displacement device driven by means of a stepper motor. As the inking unit traverses an ink-receiving roller, the stepper motor is activated for precise periods of time correlated with the position of the unit, so as to deliver measured, variable quantitites of ink for each respective increment of distance traveled by the inking unit. In practice, the copy plate is electronically scanned to ascertain the amount of ink needed for each strip zone on the copy, and this information is employed with appropriate microprocessor control to operate the pump stepper motor as required to deliver the proper variable quantitites of ink to the ink train during translation of the inking unit along the length of the ink-receiving roller. Use of a shiftable inking unit including the ink supply, pump and motor eliminates long, high pressure ink feed lines and minimizes ink wastage, particularly in short printing runs.
摘要翻译：提供了一种用于印刷机中的喷射式上墨组件，其给出了上墨辊系列的精确且容易改变的墨水应用，并且消除了传统的墨水喷射器和相关联的可调墨水键。上墨组件优选地包括具有喷墨喷嘴的往复安装的往复喷墨单元，供应墨水和供给泵，用于对连续的高粘度墨水进行加压并以恒定的流量将电荷输送到喷嘴。优选的泵是通过步进电机驱动的双螺杆反转正位移装置。当墨水单元穿过墨水接收辊时，步进马达被激活以与单元的位置相关联的精确时间段，以便为由墨水单元行进的每个相应增量的每个相应增量递送测量的可变量的墨水量。在实践中，电子扫描复印板以确定复印件上每个条带所需的油墨量，并且使用适当的微处理器控制来将该信息用于根据需要操作泵步进电机，以将适当的可变量的墨水输送到在墨水单元沿着墨水接收辊的长度平移期间的墨水列表。使用包括供墨，泵和电机的可移动式上墨单元可以消除长时间高压的墨水供给线，并最大限度地减少油墨浪费，特别是在短时间的打印运行中。

摘要： An improved continuous web handling apparatus and method for printing, handling, collating and final processing of multiple-page printed items such as business forms or the like is provided which employs separate, shiftable, track-mounted web supports having individual, pivotal, spring-biased web keepers to facilitate accurate, continuous draping of printed webs onto the supports for subsequent handling and processing thereof. In preferred forms, the apparatus includes a web fed printing press which continuously feeds printed web to a draping station adjacent the conveyor track; the draping station includes a novel, vacuum air pickup bar intermittently rotated by a five-lobe internal geneva gear mechanism, along with actuating apparatus which pivots the respective web keepers open during initial stages of web drapage and thereafter allows the keepers to close against and hold the web in place. A plurality of webs can be draped one on top of the other on the supports and/or printed on both sides thereof and thereafter removed from the supports for additional processing at speeds economical for short run printing, without fear that the webs will become unacceptably misaligned. The air pickup bar includes an improved web-engaging resilient suction pad, and internal structure for varying the number of bar ports subjected to vacuum or pressure conditions (in order to effectively handle webs of various widths). The web supports are bidirectionally shiftable, and the keepers can be operated during travel in either direction.

摘要： A dual harmonic gear phasing device forming a part of a web-forming printing tower or other web-handling station is disclosed which allows static or dynamic, 360.degree. infinite phase alterations of web-contacting rollers for coarse and fine tuning of the registration of a multiple-station printing press. The phasing device comprises an enclosed, oil filled structure having a pair of tandem coupled harmonic drive gears respectively connected through gearing or the like to the press drive and to a desired roller for phase changing purposes. Each phasing device also includes a selectively operable stepper motor coupled to one of the harmonic gears for effecting phase alterations. The harmonic gears serve as a 1:1 gear ratio transmission during normal running operations. The phasing device can be used on hard impression or perfecting printing towers, and on other types of web-handling equipment where proper registration is important, such as numbering and punching units.
