A web-fed rotary printing press ( ) for alternatively printing, in a perfecting mode, a single web ( ) or, in a non-perfecting mode, first and second webs ( ), comprises a first impression cylinder ( ) having a plurality of first blanket cylinders ( ) and a corresponding plurality of second plate cylinders ( ) arranged along a periphery of the first impression cylinder ( ). A second impression cylinder ( ) located adjacent to the first impression cylinder ( ) has a plurality of second blanket cylinders ( ) and a corresponding plurality of second plate cylinders ( ) arranged along a periphery thereof. In the perfecting mode, the single web ( ) is passed over first impression cylinder ( ) to be printed on a first side ( ) thereof and is afterwards passed through a gap ( ) between the first and second impression cylinders ( ) to the second impression cylinder ( ) to be printed on a second side ( ) thereof. In the non-perfecting mode, the first web ( ) is passed over the first impression cylinder ( ) and the second web ( ) is passed over the second impression cylinder ( ).

A multi-color single blanket printing press for printing single or dual webs includes a pair of blanket cylinders that are movable between a contacting position and a remote position. A plurality of plate cylinders associated with each blanket cylinder apply a multi-color image to each blanket cylinder. When the blanket cylinders are in the contacting position, a web passing through the nip will receive multi-color image on both sides. When the blanket cylinders are in the remote position, a pair of webs may be passed between secondary nips formed by the blanket cylinders and a pair of secondary impression cylinders. Each of the webs may therefore receive a multi-color image on one side.

Multi-color printing press for printing single or dual webs

An apparatus and method for providing disturbance-free speed and position references to drive units in a web-fed printing press to minimize or eliminate detrimental effects on printing speed and quality caused by transient mechanical disturbances occurring at one or more of the drive units during printing.

Method and apparatus for establishing an isolated position reference in

A method of removing heat from a moving web includes providing a quantity of a liquid which has a temperature of vaporization below the surface temperature of the web; heating the liquid to a temperature slightly below the temperature of vaporization of the liquid; spraying the heated liquid onto the surface of the web; and vaporizing liquid from the surface of the web to cool the web. In a preferred embodiment, an electrically charged screen is disposed intermediate the sprayer and the web. The liquid passes through openings in the screen to form electrically charged droplets of liquid which move onto the surface of the web. An apparatus for removing heat from a moving web includes liquid supply means for providing a liquid having a temperature of vaporization below the surface temperature of the web; heater means for heating the liquid to a temperature slightly below its temperature of vaporization; and sprayer means for spraying the heated liquid onto the surface of the web.

Method for cooling a web

A scanner senses the position of the individual images on the web. A cutting cylinder position is monitored by a signal generator, and may be altered by mechanically changing the phase of the cutting cylinders in relation to the image on the web based on commands relating to the image registration error, the first derivative of the image registration error and/or the second derivative of the image registration error.

Method and device for maintaining print to cut register

Web cooling device where liquid is applied to both sides of a hot web to enhance cooling via evaporation of the liquid from the web.

The position of a drive shaft of a printing press is regulated during acceleration of the printing press. A position regulator includes a first integrator and a second integrator connected in tandem with the first integrator. The first integrator provides an output signal corresponding to the integral of the difference between a first position signal indicative of the desired position of the drive shaft and a second position signal indicative of the actual position of the drive shaft. The second integrator responds to the output signal from the first integrator to provide a control signal. A control asrrangement responds to the control signal from the second integrator to accelerate the drive shaft. During acceleration of the drive shaft, the difference between the first and second position signals is driven to a value of zero.

Control apparatus

A method and apparatus are disclosed for automatically tipping closely incidental mail to magazines or the like. A plurality of magazines are sequentially fed from a source location to a town sort stacking location. A labelling station and an envelope tipping station are disposed intermediate the source and town sort location. Presorted closely incidental mail pieces are provided and scanned for zip code information. Labels are provided having subscriber information including name, address, zip code and mail piece attachment indicia indicating whether that subscriber is to receive a mail piece. Each label is scanned. If a label scanned does not include mail piece attachment indicia indicating that subscriber is to receive a mail piece, that label is fixed to the corresponding, next magazine being fed from the source location to the town sort stack location. If a label scanned does include mail piece attachment indicia indicating that subscriber is to receive a mail piece, the zip code of that label is compared to the zip code of the next to feed closely incidental mail piece. If the zip codes match, the closely incidental mail piece is tipped to the corresponding next magazine being fed from the source location to the town sort stack location and that label is discarded. If a label scanned includes mail piece attachment indicia indicating that subscriber is to receive a mail piece but the zip code of the subscriber information on that label does not match the zip code of the next to feed closely incidental mail piece, an error signal is generated.

A lift truck (16) carries a leftwardly directed ultrasonic receiver (32L) and a rightwardly directed ultrasonic receiver (32R) and an RF transmitter (34). Upon depositing its load in an assigned bin in a warehouse (FIG. 1), a load sensor (22) is actuated to cause transmission of a coded signal as to lift height and vehicle identification to a central station (60). This initiates a vehicle search by energizing ultrasonic transmitters (42-52). The ultrasonic receivers (32L and 32R) on a vehicle in a path under surveillance detect the sonic signal and relay this to the central station by way of the RF transmitter (34). The time duration which elapsed from energization of the ultrasonic transmitter to detection of the sonic signal is used to measure vehicle path depth and a comparison of the magnitudes of the sonic signals received by the receivers (32L and 32R) indicates the heading direction of the vehicle.

Object position and condition detection system

A bindery caliper is provided in the form of a non-contacting capacitive change measuring device capable of determining the page count of a multi-page stack with high sensitivity. The capacitance of a pair of plates between which the stack of pages is disposed sets the frequency of an oscillator which is sampled for a predetermined time period. The sampled pulses are counted and compared to a standard within tolerances, and the comparison determines whether the page count is satisfactory. Means for updating the standard value on the basis of accumulated measurements is also provided.

Bindery caliper

Articles to be mailed under bulk mail rates are stacked in accordance with their zip code. Articles with identical zip codes are bundled in numbers according to postal regulation minimum and maximum limits. When the number of articles in a zip code group is less than the postal minimum for a bundle, the zip code group is diverted for special handling. The system is capable of identifying consecutive zip code groups of articles each of which are under the postal minimum for a stack and bundling these together in the main stream as long as together the consecutive groups are over the minimum.

Bulk article sorting system

A method and apparatus for handling signatures such as magazines or the like which includes the on-line printing of personalized information onto materials to be inserted within a finished magazine. The system also provides on-line printing of personalized information onto materials adhered to the magazine cover, such as the address label. The on-line printed materials and the magazine or other signature are combined after the on-line printing is completed. The system operates under control of a process computer which includes means for storing the personalized information.
