Abstract: In an offset duplicating machine, an implement for marking, such as perforating, slitting, scoring or the like, each printed sheet conveyed through the machine; for transverse marking, a first marking strip is affixed lengthwise on an impression cylinder and a rotatable counter-roller is mounted adjacent and at a skew inclination to the impression cylinder; the counter-roller has an outer surface of hyperboloidal shape which allows the strip to progressively mark the passing sheet. By grooving the counter-roller or by varying the distance separating it from the impression cylinder, additional marking strips may be affixed to the impression cylinder to provide various marking configurations on the printed sheet.

Abstract: Device for the insertion, drive and ejection of sheets of paper in a printer, comprising at least one automatic paper insertion path and at least one manual insertion path for cards or sheets, these paths terminating in an insertion point in the impression device of the printer, characterized by means, arranged on the automatic insertion path, for effecting the insertion of a continuous paper band up to a predetermined guillotine point placed ahead of the said insertion point and means of cutting the band when a predetermined length has been engaged below the said cutting point, at the moment of its arrival at the said predetermined point.

Abstract: Plural printing stations are located wherever convenient within a printing machine for pressure sensitive labels. Each label is individually printed at each station by detaching the label from its release web after each printing operation, advancing the label, and reattaching the label to a different portion of the web prior to the next printing operation.

Abstract: A paper web is continuously moved by rotary drive rollers through a series of printing machines having pairs of printing rollers movable between inoperative and printing positions, and controlled and operated so that successive web sections are imprinted by the correlated printing machines only once whereby a plurality of type areas representing printed pages are printed on both sides of each web section in a predetermined pattern. After cutting of the web sections into sheets, and after collecting and folding the sheets, consecutive printed pages follow each other in a folded book.

Abstract: A method and apparatus for providing or maintaining accurate register of a web with mechanisms operating on the web. The web is driven substantially without slippage at a first position on the web path and a register roller is positioned at a second position on the web path. The register rollers and web are caused to engage without substantial slipping relative to each other. The web is driven at the first position and by the register roller at speeds which have a substantially constant ratio to one another so that web elongation therebetween is substantially constant.

Abstract: Disclosed is a sheet splicer for splicing sheets of paper, sheet or film, especially for splicing paper rolls together to form a continuous web joining the old and new rolls of paper when used in continuous web printing presses so that they can be spliced together by a butt end splice. A traverse blade cuts both the old and new plies along a butt edge line. The blade is followed by a tape applicator and paper stripper which strips the selvage and then joins the plies together as a butt edge seam of the old and new sheets. The splicer is designed as a stand alone unit or as an in-place attachment for a printing press.

Abstract: Printing apparatus which receives printing stock in roll form, withdraws a predetermined amount of material from the roll, cuts the withdrawn material to provide a sheet of stock for printing, and then feeds the sheet to a printer. The printing apparatus can overprint onto sheets which are cut from a roll of preprinted stock, or can print on sheets which are measured and cut from blank roll stock. When used with preprinted stock including a printed material code, the printing apparatus reads the material code to verify that the proper printing stock is being used, and automatically interrupts the printing operation if the proper stock is not present.

Abstract: A removable redeemable coupon for newspaper advertisements and method and apparatus for producing same wherein the newspaper is printed in a rotary web press having a plurality of pairs of printing plate cylinders and blanket cylinders between which the web moves during the printing process. Printing plates secured in position on printing plate cylinders of certain pairs to print the faces of the web with news and advertisements including display advertisements with a redeemable coupon included therein.

Abstract: A sheeter for feeding sheets in shingled relation to a point of collection including a source of sheets, a first conveyor belt and a second conveyor belt operating at substantially reduced speed so that the sheets are collected thereon in shingled relation. For snubbing the successive sheets so that they are decelerated and uniformly spaced on the second conveyor belt, a snubber is provided in the form of a knock-down roller arm rotating in a vertical plane at the upstream end of the second conveyor belt and so spaced therefrom as to press a sheet into engagement with the second conveyor belt, the arm being driven at a rotary speed which is synchronized with the source, with means being provided for adjusting the phase of the arm with respect to the source so that the arm engages the tail of each successive sheet.

Abstract: The invention provides apparatus for producing printed and cut blanks from continuous webs of cardboard or the like, which avoids wastage between successive blanks when the length of the blank is not equal to the periphery of the treatment rolls of the apparatus by using two coupled accelerators which adjust the position of the web after each complete operation.

Abstract: A strip of label material is fed from a supply roll to a preprint unit which incorporates a set of strip feed rolls driven by an electric motor-reducer drive unit. The drive unit is adapted to be stopped by a rotary solenoid actuated brake controlled by a photocell which senses the advancement of the strip. A print drum is rotatably supported above the generally horizontal path of the strip and has peripherally spaced axially extending rows of printing characters. A set of hammer members are positioned under the print drum and are selectively actuated by a corresponding set of solenoids. The print drum is indexed at a high speed by an electric stepping motor which automatically returns to a start position, and the printing characters are inked by a ribbon which is advanced by another electric motor-reducer drive unit pivotally supported to provide for automatically reversing the feed direction of the ribbon.
