  • Patent number: 4815376
    Abstract: Offset printing press which comprises, in combination, a set of means making it possible for it to carry out, either independently or simultaneously, sheet-fed or web-fed printing. These webs are presented equally well either as perforated and prefolded pages or as reels. A set of mechanical movement pieces, working together with the removable components, makes it possible, depending on the types of printing to be carried out, to provide the press with twenty possibilities of different printing modes. A movable press-cylinder 17 (FIG. 3), working together with the blanket of the removable blanket cylinder 3A, makes it possible to prevent the web-fed printed matter, during its printing, from passing through the press and, by so doing, to make these two modes of feeding and printing, sheet-fed and web-fed, totally independent of each other. The same type of removable device as that fitted on the mixed press, also mounted on a sliding frame 64 (FIG.

  • Patent number: 4438696
    Abstract: The module is adapted to be attached to and suspended from a flexographic printing press in order to provide an additional web printing station and other options such as an ultraviolet curing device and a die cutting station. Guide rollers for the web being printed are so positioned that the web may be entrained around them in a manner to present the web to the print station of the module for backside printing thereof after the front side of the web has been printed by the primary press. The module derives its driving power for the various rollers and other components thereof from the primary press, and a quick change feature within the drive coupling between the press and the module enables the rollers of the module print station to be driven in a reverse mode for such backside printing, notwithstanding the fact that the print stations of the main press remain driven in the forward mode, as well as the web.

  • Patent number: 4416200
    Abstract: In die cutting the impression roll is maintained at constant peripheral velocity and the web, while engaged by the die, travels at the peripheral velocity of the impression roll. As the trailing edge of the die approaches the nip formed by the impression and complementary rolls, one or both of the feed rolls driven by the web is clutched into a cam mechanism for positive driving at a constant velocity equal to the die-induced velocity of the web. This constant velocity driving of the web jointly by the die and feed rolls continues until the die releases the web beyond the aligned centers of the treatment rolls when the web comes under exclusive control of the feed rolls.

  • Patent number: 4408906
    Abstract: An apparatus for encoding magnetic data and printing on a plurality of closely spaced labels releasably mounted on a supply roll of carrier strip, includes a magnetic head for encoding the labels and a printer for printing on the labels. The carrier strip extends from the supply roll past the magnetic head and to the printer, and forms a variably sized loop between the head and the printer. The variably sized loop has a gap, across which an encoded label may be transferred so that movement of a label past the printer is independent of movement of the supply roll. The magnetic head is movable parallel to the carrier strip so that the plurality of labels may be encoded and printed without reversing the supply roll, thus increasing the speed at which labels may be encoded and printed. The speed of the movable head may be precisely controlled to ensure accurate encoded. The encoded data is verified when the magnetic head moves over the label back to its original position.

  • Patent number: 4334471
    Abstract: A printing system is disclosed which permits the printing of indicia on a continuously moving web at a fixed position offset from previously printed, evenly spaced web marks. The fixed position of the printed indicia relative to the web marks is independent of the velocity of the web. A web mark sensor, which may be part of the system to which the present invention is retrofitted, detects the passage of each previously printed web mark past a detection position. A registration circuit controls the timing of the printing of the indicia on the moving web and provides START signals for a servomotor-driven rotary print head which includes one or more peripherally mounted printing elements. A tachometer is mechanically coupled to a web transport mechanism to produce an output voltage which provides the velocity command for the servomotor drive of the rotary print head to match the rotational velocity of the print head to the linear velocity of the web during the printing interval.
