  • Patent number: 4325301
    Abstract: An apparatus for shifting the paper web feed through a web-fed rotary printing press is disclosed. The paper web passing through the printing press contacts one or more fixed guide rollers and a shiftable guide roller carried at a free end of a pair of movable shifting bars. These shifting bars can be rotated about their fixed ends to shift the position of the shiftable guide roller and hence the paper web thus allowing access to portions of the printing press. A support platform is carried by the web shifting apparatus to provide a standing area for an operator or workman when the paper web is shifted out of its normal position.FIELD OF THE INVENTIONThe present invention is directed generally to a paper web shifting apparatus for a web-fed rotary printing press. More particularly, the present invention is directed to a paper web shifting apparatus utilizing a shiftable guide roller.

  • Patent number: 4305332
    Abstract: A two-web, dual purpose printing press and method is provided which can be used to "make ready" and proof gravure rollers on a first web, and to print a sample using the rollers on a second web and under substantially identical conditions during both operational modes. The press includes an interchangeable gravure roller, a pair of impression rollers, (one associated with each of the webs), and structure for selective shifting of the impression rollers between positions wherein each roller alternately forms a web-receiving and printing nip with the gravure roller. A motion-limiting stop arrangement is provided to insure that the respective impression rollers assume a substantially identical position relative to the gravure roller during the respective operational sequences of the press; in this manner printing conditions are uniform during both proofing and sampling.

  • Patent number: 4276112
    Abstract: A system is provided which weighs packages and applies individualized labels to each package indicating the weight of the package, the date, or other desired individualized information. A conveyor includes a weighing section where the weight of the product is converted into digital form and supplied to a data processing system. Individual labels are printed by electrostatic techniques including both bar code machine readable designations and alpha-numeric characters. The label printing and applying apparatus includes a print station, a toner application station, a fusing station, and a peeling blade for separating the label from the backing sheet, and an applicator station. As the individual labels are advanced to the applicator station, blank labels will pass under the print and toner stations, and these labels will not be charged or toned, so that the tape may be reversed and moved back to the appropriate position for applying individualized data to these blank labels.

  • Patent number: 4201132
    Abstract: A broad textile web, on its way to a processing station such as a rotary-screen printer, passes around a set of closely juxtaposed but independently rotatable feed rollers that are individually driven via respective differential gear trains each having a first input connected to a common drive shaft and a second input connected to an ancillary stepping motor. Each feed roller engages a strip zone of the web which is scanned by an associated sensor upstream of the roller, the latter detecting the leading and trailing edges of recurrent transverse web sections--e.g. of pile fabric--mechanically, electrically or optically distinguishable from intervening sections. Unequal longitudinal tensions in the several strip zones actuate the sensor-controlled stepping motors for different time periods so as to cancel any relative deformation.

A control system for a printing press comprises means to detect and measure the magnitude of a repeat length error as it is printed by a key color deck and further comprises means to correct for the repeat length error by varying the tension on the web ahead of the key color deck. The system includes means for establishing high and low limits within which repeat length errors of certain magnitude are likely to occur and for which correction is made. The system also includes means for warning the press operator that there is a trend in the change in magnitude of repeat length errors to exceed the limits so that the press operator may either establish new limits or establish a new base repeat length within the same limits so that repeat length errors of a different magnitude (usually smaller) are likely to occur.

  • Patent number: 3949864
    Abstract: A fabric printing machine having a conveyor belt for supporting a fabric to be printed. A drive unit is connected to the belt, and a control mechanism coacts with the belt and the drive unit for permitting intermittent unidirectional advancing movement of the belt through a selected distance. The drive unit includes a first drive for advancing the belt at a fast speed and a second drive for advancing the belt at a slowspeed. The control mechanism includes a belt engaging device adapted for gripping engagement with the belt for causing synchronous movement of the belt and engaging device during the advancing movement. The control mechanism also includes means for activating the belt engaging device and for causing the first and second drives to be sequentially connected to the belt for moving the belt at fast speed through a first preselected distance and thereafter moving the belt at slow speed through a second preselected distance.

  • Patent number: 3945317
    Abstract: Automatic registration of the web of sheet material on a printing cylinder is effected in a silk screen printing apparatus which includes a printing frame reciprocably movable in an impressing and return cycle. A printing cylinder is arranged for carrying a web of sheet material in impression receiving relation to said printing frame during the impression-forming portion of its movement. Web guide rollers are arranged to direct the web to and from said printing cylinder. A first drive arrangement, including a first motor, is connected both to drive the printing frame reciprocably and said printing cylinder unidirectionally in the impression-receiving direction. The printing cylinder is disengaged from the first drive during the reverse travel of the printing frame so that the web is stationary. A second drive arrangement is provided, including a second motor, connected to drive the printing cylinder in a second direction, that is the reverse of the printing direction.

  • Patent number: 3938437
    Abstract: The unwind controller drum for metering web material into a web processing machine is positively driven by a positive, fixed-ratio drive train. Several drive ratios are selectively available, each differing only slightly from another to provide minute changes in the drive ratio from the drive to the unwind drum. The changes in drive speed are generally less than .05% to provide positively determined, finite adjustment of the rate that the web material is metered into the web processing equipment.

  • Patent number: 3930446
    Abstract: A duplicating method and apparatus in which information is transferred onto a copy web from a master web and a repeat printing roll and in which a common impression cylinder carries the copy web past a pressure roll which cooperates with the impression cylinder for bringing the master web in printing contact with the copy web to print equally spaced indicia from the master web on the copy web and the repeat printing roll cooperates with the impression cylinder for printing repeat indicia on the copy web, and including a sheeter for separating the copy web at spaced lengths, each length including an impression from the master web and an impression from the repeat printing roll.
