Definitions

  • an imprint there is a need to apply to each increment which will become an individual form, an imprint.
  • a typical illustration is where the web is payroll check stock to which, in connection with computerized printing of payee name, amount, date, and stub infomation, e.g. as to withholding, accumulated or used leave time and the like, an authorized signature must be applied, so that the person to whom the check is issued will be able to negotiate it, deposit it or cash it.
  • a conventional way of applying an authorized signature at the correct location on each of a series of checks which remain connected in web form is by means of a rotary imprinting cylinder bearing in reverse a reproduction in printing plate form of the authorized signature of the maker's treasurer or the like.
  • One conventional way of mounting and powering an imprinter involves mounting it to a detacher and supplying it with rotary power therefrom.
  • United States Patent Specification No 3070009 describes a burster imprinter including infeed rollers and outfeed rollers with the outfeed rollers driven at a faster rate than the infeed roller so that continuous form stationery fed between the rollers is burst at cross perforations on the continuous form.
  • the mechanism also includes imprinter mechanisms for applying an imprint to the stationery before bursting which mechanism includes an imprinting roller with means for replacing the roll with a different size of imprinting roll and utilizing a different size of gear and means to ensure that the driving gears are brought into mesh.
  • German Patent Specification No 606446 describes a machine for printing on a fabric web with contact with a freely rotatable drum.
  • the pressure roller is mounted on a pivoted control rod and operation under the control of a crank fin so that the pressure roller may be moved into and out of contact with the fabric web.
  • German Specification No 1241843 describes a printing machine including a printing cylinder controlled by a mechanism including a pair of levers which supports a bearing at, one end thereof and at the other end has feed rollers operated by eccentrics.
  • the invention provides a rotary imprinter as defined in the claims appended hereto.
  • An imprinter roller having an imprint-applying element and which is designed to be incorporated in a line of business form stock processing equipment so as to rollingly apply an imprint to the stock while the stock is advancing along the line in web form is equipped to apply the imprint at a succession of corresponding sites which are separated from one another longitudinally of the web, by a distance which is greater than the circumferential dimension of the imprinting roll.
  • the distance between the sites is twice the circumferential distance and the imprinting roll is mounted and powered by elements which pivotally cam one end of the imprinting roll away from rolling contact with the web precisely at alternate times when its imprint applying element is about to begin to contact the web.
  • the imprinter is operated in conjunction with, ie is mounted to and receives rotational power via, on otherwise conventional detacher.
  • Figure 1 depicts at 10 an existing imprinter detacher, eg a Moore 3410 Imprinter Detacher having a 5-1/2 inch (13.97 cms) print cylinder assembly 12 including an imprinting roll having a radially outer peripheral surface provided with an imprint applying element which extends thereon throughout substantially less than the full circumferential extent of said surface which, in use, imprints an imprint every 5-1/2 inches (13.97 cms) at a corresponding site on a web of processed business form stock being fed to the apparatus 10 in a business form stock processing line, then separates the web into increments, along transverse lines of weakness, so that each web constitutes a processed business form bearing an imprint and with means journalling said imprinting roll for rotation about its own longitudinal axis.
  • an existing imprinter detacher eg a Moore 3410 Imprinter Detacher having a 5-1/2 inch (13.97 cms) print cylinder assembly 12 including an imprinting roll having a radially outer peripheral surface provided with an
  • journalling means are also provided for mounting said journalling means in juxtaposed relation to a processing line for a longitudinally advanced web of flexible- material such as paper so as to permit said imprinting rolls to rotate in working position with said imprint applying element of said peripheral surface in tangential rolling engagement with a face of said web.
  • the purpose of the invention is to provide a modification which disturbs, the existing device 10 as minimally as possible but makes it easy for an operator to readily reconfigure the device 10' ( Figure 2) as modified, so as to print an imprint either every 5-1/2 inches (13.97 cms) or every 11 inches (27.94 cms), without otherwise significantly detracting from any capabilities of the device 10.
  • the invention is concerned with being able to apply successive imprints to the web at respective sites located at distances spaced from one another longitudinally of the web by a uniform amount which is greater than the circumference of the imprinting roll thereof. This is achieved by a rotary imprinter according to claim 1.
  • An extension 12' is added to a conventional 5-1/2 inch (13.97 cms) imprint cylinder assembly, 1/4 inch (0.63 cms) is cut from the lower slitter shaft and collar retainer of the device 10, a 35-tooth gear 14 is clustered with the existing 35-tooth impression cylinder gear on the device 10, for powering a 70-tooth, 20 pitch 20° P.A. idler gear 16 with a flat formed on its hub.
  • a bearing pivot arm 18 is provided to raise the 5-1/2 inch (13.97 cms) print cylinder and printing plate, allowing the 5-1/2 inch (13.97 cms) print cylinder to rotate two revolutions for each impression imprinted thereby. No holes need to be drilled in the device 10 for modifying it into a device 10'.
  • For imprinting 5-1/2 inch-depth (13.97 cms) forms instead of imprinting 11 inch-depth (27.94 cms) forms, a minor change is made to the bearing and collars on the modified 5-1/2 inch (13.97 cms) imprint cylinder extension. This allows the 5-1/2 inch (13.97 cms) imprint cylinder to be disengaged from the lift pivot arm.
  • the lift pivot arm is disengaged from the hub of the 70-tooth gear, by using an expansion spring 20 to lift the pivot arm off the hub.
  • the main parts of a kit for modifying the device 10 to become the device 10′ include: one modified 5-1/2 inch (13.97 cms) imprint cylinder assembly, two 35-tooth, 20 pitch 20° P.H. gears, two 1/4 inch (0.63 cms) collars, two bearings, a lift pivot arm, a 1/4 inch (0.63 cms) I.D. x 3/8 inch (0.95 cms) O.D. bushing, a 70-tooth 20 pitch 20° P.A.
  • gear a 70-tooth gear idler mount bracket assembly, an idler pulley bracket assembly, a pulley, a spring, a 5/8 inch (1.59 cms) collar, a spacer idler bracket, a modified lower slitter shaft and a 3/8 inch (0.95 cms) x 1/4 inch (0.63 cms) collar, together with several miscellaneous retainers, washers, screws and nuts.
  • a pair of Mylar® guides which clip onto the upper slitter support shaft and lay on top of the paper web as it goes under the print cylinder may be installed to handle tented forms, etc.
  • the unit 10′ When the unit 10′ is run with a new ink roll the unit might leave a "shadow" print in the area which should not be contacting the plate during the non-print revolution. Because the imprint plate is making two revolutions past the ink roll but is only printing once, the plate is being inked heavily and this heavy coat of ink is being transferred to the form and will not be dry when it passes through the slow rolls. It is possible that some ink may offset to the upper slow roll and then be deposited onto the form. If this "shadowing" occurs look closely at the imprint and if it is comprised of small dots, the imprint is transferring from the upper slow roll. Rolling off the excess ink from the ink roll onto a pad of paper should elminate this condition.
  • the 70-tooth cam gear 16 is driven by the cluster gear 14.
  • the 70-tooth gear has a cam surface 22 on which rides the end 24 of the cylinder lift pivot arm 18.
  • the cylinder lift pivot arm has a fulcrum at one point in the upper right hand portion.
  • the follower spring 20 is attached above the fulcrum point so that an upward pressure is exerted on the cylinder lift pivot arm.
  • the 5-1/2 inch (13.97 cms) print cylinder 12 shaft extension 12′ passes through a bearing block which slides up and down in a channel on the side frame of the detacher. The shaft extension is only on one end of the print cylinder and rides on the cylinder lift pivot arm.
  • the cluster gear 14 is belt driven from the motor drive for the detacher 10′.
  • the end of the cylinder lift pivot arm rides on the cam surface, pivoting about the fulcrum point.
  • the cylinder lift pivot arm travels up over the high point of the cam surface, one end of the 5-1/2 inch (13.97 cms) print cylinder is raised from the surface of the web of form stock passing through the detacher.
  • the 5-1/2 inch (13.97 cms) print cylinder makes approximately one revolution in the raised position, and as the pivot arm continues to travel on the cam surface, it reaches the low point of the cam 24, causing the arm to drop, which causes the print cylinder to drop to the surface of the paper for the next revolution and imprint.
  • the cylinder lift pivot arm is once again raised which in turn raises the print cylinder from the surface of the paper.
