Abstract: A register control for web processing apparatus operates to match the surface speed of a metering roll which supplies a preprinted web to a cutting zone in a cutter mechanism to the surface speed of an impression cylinder which applies impressions and associated register marks to said web. The register control also effects registration between the impressions and the cutting zone. The web processing apparatus comprises a register control motor for the metering roll and a movable dance engageable with the web at a location between the impression cylinder and the said metering roll.

Abstract: A registration controller for sensing the presence and location of registration marks on a web as the web passes a scanner, and for generating a signal for use in controlling downstream operations such as cutting and/or printing operations. The controller includes a light source located remotely from the scanner. Light from the source is directed to the scanner and onto the web. The web reflects the light, the amount and intensity of the reflection depending upon the color and reflectivity of the particular area of the web on which the light is being currently directed. The reflected light is directed to a photo receptor which converts the reflected light to an analog electric signal, the level of the signal being determined by the amount and intensity of reflected light, within a particular predetermined range. This analog electric signal is then amplified, processed and converted to a digital signal for use in controlling the aforementioned downstream operations.

Abstract: The delineating cylinder of the web apparatus of this invention has a cutout around one-third of its periphery to be out of contact with the web through an idle phase of its rotational cycle during which a web portion at that cylinder is drawn rearward through an adjustably variable distance. Through the remainder of that cycle that web portion is moved forward in step with delineating cylinder rotation. Upstream and downstream from that cylinder are feed roller pairs, driven through a variable ratio planetray transmission, whereby other portions of the web are moved forward steadily at the rate of one repeat interval length per delineating cycle. Between each pair of feed rollers and the delineating cylinder is a control roller around which there is a loop of web. Each control roller is moved bodily in an orbit whereby its loop is alternately increased and permitted to decrease. The radius of its orbit is adjustably variable for variation of repeat interval length.

Abstract: A sheet handling device for receiving a flow of sheets from a discharge end of a processing apparatus and the delivering the sheets into an input end of a second processing apparatus characterized by a first conveying path of belts extending between an input end and exit end of the device, a second conveying path of belts having a longer or greater length than the first path extending from the input end to the exit end, nip rollers forcing the belts of each path into engagement with each of the sheets in the first and second paths to impart a new speed thereto, the ends of the first and second paths being arranged so that a sheet in the second will be deposited on a following sheet traveling in the first path, and a device arranged adjacent the input ends of each of the paths for alternately directing the sheets into said paths.

Abstract: A sheet handling device for receiving either a flow of sheets or a flow of transverse rows of interconnected carton blanks from a discharge end of a processing apparatus and delivering the sheets or rows into the input end of a second processing apparatus characterized by a first conveyor path of belts extending between the input and exit ends of the device, a second conveyor path or belt having a longer or greater length than the first path extending from the input end to the exit end, nip rollers for forcing the belts of each path into engagement with each of the sheets in the first and second path to impart a new speed thereto, the ends of the first and second paths being arranged so that the sheets in the second path will be deposited on a following sheet traveling in the first path and a pivotable blade arranged adjacent the input ends of each of the paths for alternately directing the sheets into the paths.

Abstract: A system for controlling the emission of solvents from a printing press having a plurality of printing stations characterized by the solvents being evaporated from the ink solution in a drying hood or section of each of the printing presses and the volatile organic compound of the solvents being converted into harmless gases by heating in an oxidation chamber. The exhaust from the oxidation chamber is recirculated back to the drying hoods so that the amount of fresh air being brought into the system is minimized to reduce the amount of exhaust gases being discharged back to the atmosphere to minimize the amount of the volatile organic compounds being discharged to the atmosphere.
