  • Patent number: 5486254
    Abstract: A system of incrementally moving a foil, or other flexible and elastic elongated web, through a work station, by contacting and registering the foil on both sides of the work station. An example of such a work station is a hot stamping press that transfers optical images from the foil to other substrates. A drive mechanism, with an associated foil registration device, is provided at each of the entrance to the work station and the exit from it. Each registration device optically detects registration marks provided on the foil along its length, and is used to stop its associated drive mechanism after a predetermined number of marks have passed. This dual drive system maintains registration of the foil or other web throughout an extended work station. It is particularly advantageous for use with those hot stamping presses that either have a large number of die or whose multiple die are widely separated, since the multiple images carried along the foil are then all properly registered with the die.

    Abstract: A register control system, particularly one that registers marks on a printed web to a function cylinder, produces proportional and integral gains each independently variable to control the take over point of the integral gain with respect to the proportional gain. The accumulating integral gain is zeroed out after cross over if the proportional gain exceeds a preset percentage of the integral error band. The overall system gain is varied with the line speed independently of the proportional and integral gains to provide speed-insensitive control. The direction of automatic correction is always selected to return the system to register in the shortest distance possible. High frequency clock pulses are counted between encoder pulses to interpolate with high accuracy the angular position measurement of the marks and a homing pulse.

  • Patent number: 5279453
    Abstract: An automatic document feeder (ADF) for use with an electrophotographic copier, digital copier or similar image recorder for selectively feeding ordinary documents in the form of separates sheets and a continuous document in the form of computer form (CF) paper. Sprocket holes formed through the CF paper are sensed to controllably transport and stop the CF paper on the basis of the number of sensed holes. Even when the first print area of the CF paper is set on a platen by hand, the paper can be surely transported and stopped page by page to the last print area. Regarding the last print area, the stop position is determined on the basis of the number of sprocket holes having been counted until the trailing edge thereof has moved away from a sensor. Hence, whatever the deviation of a print area relative to the CF paper may be, all the print areas including the last print area can be accurately set on the platen to reproduce complete images.

  • Patent number: 5224640
    Abstract: An off-line web finishing system performs plural functions on a pre printed and rewound web at a series of pieces of equipment arranged in a line. Tension in the web is set at a variable infeed at a constant value that is sufficient to facilitate handling of the web. A common web-transport system drives all draw rolls in the line in unison, at the same speed, and without slippage between the web and the rolls. In the preferred form, a second drive line rotates in unison the function cylinders of pieces of equipment that are registration sensitive. The second line is driven by a main line shaft of the web transport system via a variable transmission that is adjusted in response to at least one optical scanner that senses misregistrations between the printed pattern on the web and the function cylinders. The registration sensitive function cylinders operate on the web only intermittently.

  • Patent number: 5193727
    Abstract: A system for incorporating, in the production of a continuous stream of images, by an image transfer device upon a moving web, post-production operations upon the web at various locations. Locations of a web, having a plurality of images placed thereon, output from an image transfer device are tracked. Specific operations at various locations upon the web are performed by a post-production device as the web passes through it. The web is directed from the image transfer device to the post-production device. In response to the tracking of locations upon the web, the point when a location has entered the post-production device is determined. In response to this determination, the post-production device is commanded to perform its specific operation at a connect location.

  • Patent number: 5163008
    Abstract: In a method and apparatus for cutting either a single sheet or a lay-up of sheets of material to derive pattern pieces or the like from the material, the material is cut segment-by-segment by bringing a fresh segment to a cutting station after a preceding segment has been entirely cut. Discontinuities, which may translate into points of non-clean cutting, which might otherwise occur in cut lines as they pass to one segment to another, because of accidental shifting or mispositioning of the material during advancement, are avoided or reduced by acquiring the start and finish X and Y coordinates of an index point on the material and then using such coordinates with the cutting instructions used in the cutting of the subsequent segment, the use of the coordinates being such that accidental shifting or mispositioning of the material is taken into account and compensated for in the cutting of the second segment.

  • Patent number: 5061947
    Abstract: A microprocessor controller thermal printer particularly usable in a hand-held labeler for printing labels on a composite web detects indices on the web and automatically adjusts the distance that the web is advanced based on a measurement of the distance between indices made during a paper loading sequence. The printer includes automatic jam detection that measures the length of time that one of the indices is being detected and provides a jam indication if it is detected for more than a predetermined time period. A solenoid operated braking mechanism retains the web in position upon completion of a printing cycle to prevent the web from being moved relative to the print head while the label is being applied.

  • Patent number: 5061946
    Abstract: A microprocessor controlled thermal printer particularly usable in a hand-held labeler for printing labels on a composite web detects indices on the web and utilizes the detected indices to position the labels relative to the print head. The printer utilizes an improved index detection system that compensates for variations in index size and density and for variations in sensor sensitivity by detecting both the leading and trailing edges of an index and utilizing the distance between the detected leading and trailing edges to determine the length of the index. By dividing the length thus determined by two, and by advancing the web by this amount after the detection of the leading edge of an index, the center of the index can be accurately located, and the web can be accurately registered at any desired position relative to the center of the index.

  • Patent number: 5041070
    Abstract: A bag machine includes a programmed logic controller intermittently actuating a web feed draw roll motor for controlled web feed during the inoperative period of a cycled seal bar. The controller has separate inputs for the seal bar periods and a web length and establishes a control program of a preferred motion profile, with acceleration and deceleration of the fixed rolls to match the bag length to the available time using the total time available, with acceleration to a maximum and deceleration to reference, with or without a constant speed period. The bag length and time is monitored each machine cycle to calculate the next motion profile and permit changes in the bag length without machine shut-down. A programmed registered mode of control responds to a web mark spacing relative to the seal bar. In the registered mode, a photoscanner detects the mark during a constant speed web feed period prior to the end of the available time and actuates the web feed accordingly.

  • Patent number: 5017943
    Abstract: In a thermal transfer type color printer, an ink film on which plural color inks are sequentially painted in its longitudinal direction is sequentially transported forward between an ink film supply roll and winding roll, while a printing paper is repeatedly transported forward and backward in order to print out a color image by overlapping plural color inks. In color printing, the printing paper and ink film are partially overlapped and wound around a platen roller, and a thermal head is pressed against the platen roller by sandwiching the ink film and printing paper therebetween so that the thermal head transfers the color inks on the printing paper. In order to prevent wrinkles from being formed on the ink film, tension applying means applies tension force to the ink film by temporarily controlling or stopping revolution of the ink film supply roll.

  • Patent number: 4984458
    Abstract: A method and apparatus for measuring the relaxed length of a moving web includes forming a plurality of detectable marks along the length of the web at a repeated length interval. First and second detectors positioned along the web path are separated by a known distance S. A first tensioning force is applied to the moving web, and a first tensioned repeat length of the web is measured by detecting a mark moving past the first detector and then detecting the next mark moving past the second detector. The time separating the detections is determined. A second tensioning force of a known proportional relationship with the first tensioning force is applied to the moving web. A second tensioned repeat length is measured. The speed of the moving web is measured, and a relaxed length is calculated from the first tensioned repeat length, the second tensioned repeat length, and the proportional relationship between the first and second tensioning forces.

  • Patent number: 4924266
    Abstract: In a printer for printing information onto a continuous form, at least one of opposite side edges of the continuous form is detected by a side-edge detecting arrangement. It is judged that a traveling abnormality of the continuous form occurs, when a detecting signal representative of the at least one side edge of the continuous form detected by the side-edge detecting arrangement continues for a preset period of time and more. If the continuous form is provided therein with sprocket holes, the side-edge detecting arrangement may include a pair of side-edge detectors each for detecting the sprocket holes in a corresponding one of opposite side edge portions of the continuous form. In this case, it is judged that the traveling abnormality of the continuous form occurs, when the detecting signal representative of the sprocket holes in each side edge portion of the continuous form is not continuously outputted within a preset period of time and more.
