Abstract: A quarter folder for signatures which has a deflector or guide means to maintain a side of the signatures in an arcuate configuration.

Abstract: An apparatus which can shingle a series of products and a method relating thereto, the apparatus, in one embodiment, having first upper and lower moving surfaces to receive a product, a second upper moving surface at an exit end of the first moving surfaces, the second upper surface being angled downwardly, a deflector to deflect the leading edge of the product moving along the second upper moving surface, and a second lower moving surface located below the deflector to receive a product. The device provides a positive control for the product and eliminates the use of delivery fan (fly) systems. Also provided are devices to reform various combinations of copies as used in the printing industry.

Abstract: An apparatus for adjusting paper copies which are skewed and for providing a shingled stream, the apparatus including an input, a singulating device having a vertically movable gate member, a first abutting surface formed on the gate member, a second fixed abutting surface formed rearwardly of the movable gate member, a gate member being reciprocally driven in a vertical direction, and an output section to receive copies from the singulating device. The apparatus can be used in conjunction with other copy handling machines such as various integrators.

Abstract: A system for controlling a temperature of a rotary machine having a hollow roller chain with ink vibratory rollers and a plate cylinders such as used in a printing head, the system comprising a heat transfer fluid, a device for cooling the heat transfer fluid, a closed loop conduit, a device for passing the heat transfer fluid through the ink vibratory rollers, a solenoid valve mounted on the conduit, the solenoid valve being either fully opened or fully closed, temperature sensors to sense the temperature of the ink vibratory rollers, and a reservoir for the heat transfer fluid. The solenoid valves being either fully opened or fully closed allows for quick and precise temperature adjustments in real-time within a very narrow range.

Abstract: A process temperature control system for a rotary processing machine involving one or more process fluids by using an external liquid coolant from a central source of heating and cooling applied to one, or more transmission train of rollers for the process fluids of the rotary machine to effectively control the process temperature of those process fluids in real time and to use these process fluids themselves as the means to achieve process temperature control for the whole rotary machine. One such rotary processing machine is a rotary printing press equipped with conventional lithography printing plates or waterless printing plates by using its hollowed ink roller train to receive internal coolant to effectively control the temperature of the ink to optimize its own process characteristics and to use this fluid (ink) itself as it moves through the lithographic process as a direct cooling/heating media to control other important lithographic process temperatures in real time.

Abstract: A system for metering the volume of a liquid, e.g. ink, supplied by a positive displacement pump to an installation, such as a printing press, employs a device for generating a first series of signals each indicative of completion of a pumping stroke. The speed of the pump is also sensed to generate a second series of signals each indicative of the positive supply of liquid by the pump. The signals of the first series are counted only in the presence of a corresponding signal of the second series. The result is an accurate numerical indication of the total volume of liquid pumped.
