Patent number: 4393774Abstract: A label applicator for self-adhesive labels is disclosed.The applicator includes cam tracks which control the orientation of two pivotal print-heads during motion from a rest position to a printing position. The print-heads are mounted on levers pivoted in the casing so that motion of the print-heads takes place about two pivot centers. A rotary inking roller is positioned along the path of the operative facets of each print-head and inking takes place during movement of the corresponding print-head to ensure contact during one part of the cycle and avoids such contact during the return. The roller acts as a part of the cam track. The inking action is such that the roller is rotated by the operative facets. At the instant printing takes place, a part of the cam track serves to prevent later motion of those print facets.The invention can be applied to label applicators (or dispensers) wherever there is a need for high quality printing on labels.Type: GrantFiled: September 29, 1981Date of Patent: July 19, 1983Assignee: Norprint InternationalInventor: Anthony V.

Patent number: 4183298Abstract: An ink roller for a printing press having a cylindrical outer shell presenting a roller surface and having a control fluid-displacing core, a hollow cylindrical partition being interposed between the shell and the core to define inner and outer annular passageways connected in series having respective inlet and outlet openings.

Patent number: 4126090Abstract: An inking ring and wheel for code daters, the ring being formed as an elongate length of ink absorbent strip material of generally rectangular cross-section arranged secured end to end to define a ring, said ring being seated in a thin wall U-shaped shell whereby the outer portion of the ring extends radially from the shell so that a portion thereof is disposed outward of the shell. Preferably, the strip is formed of foam rubber and the shell is formed of uncured rubber. A slurry of a solvent and uncured rubber is used as an adhesive for joining the ends of the strip, as well as the strip to the shell. The assembly is vulcanized to effect permanent securement. The thus formed inking ring is mounted upon a cylindrical hub and a pair of side plates retained thereon on both sides of the inking ring to define an inking wheel.Type: GrantFiled: May 25, 1977Date of Patent: November 21, 1978Assignee: Kiwi Coders CorporationInventor: James G. McKay

Patent number: 4121521Abstract: An inking wheel having an outer ring of firm inking material, the outer ring being mounted upon a radially yieldable support assembly, said support assembly formed of a pair of relatively rigid concentric cylindrical sleeves and a resilient cushioning material disposed between said sleeves. The inking wheel can be mounted upon a shaft, a hub or mounting spindle. Axial disks can be provided to restrain axial movement of the ring and the support assembly.Type: GrantFiled: June 29, 1977Date of Patent: October 24, 1978Assignee: Kiwi Coders CorporationInventor: Bernard J.

Patent number: 4116747Abstract: There is disclosed a labeler having a frame and a subframe, with a print head movably mounted on the subframe for cooperation with a platen. A label hold-down member is disposed in overlying relation to the platen. The subframe carries a label roll composed of labels releasably secured by pressure sensitive adhesive to a web of supporting material, and the subframe defines a path for the web. The label roll is mounted on improved mounting structure. A manually operable actuator drives a gear which in turn effects movement of the print head. The gear carries a pivotal pawl which drives a ratchet wheel. The ratchet wheel and a toothed feed wheel mounted in the subframe are adjustable with respect to each other. A die roller cooperable with the toothed wheel is spring-urged against the toothed wheel. The frame includes a movable frame section mounted on a pivot to facilitate easy replacement of an ink roller. The pivot also mounts an applicator roll and a leaf spring of the inking mechanism.Type: GrantFiled: April 25, 1977Date of Patent: September 26, 1978Assignee: Monarch Marking Systems, Inc.Inventor: Paul H. Hamisch, Jr.

Patent number: 4054685Abstract: A wiping cylinder is coated with a synthetic resin plastic composition by rotating the cylinder downwardly past a straight-edge blade on which the plastic composition is supplied so that a thin uniform layer is spread onto the cylinder. The blade is progressively retracted from the cylinder so that successive layers are applied to provide the desired total thickness. Provision is made for first heating and then cooling a layer after it has been applied.Type: GrantFiled: May 2, 1975Date of Patent: October 18, 1977Assignee: De la Rue Giori S.A.Inventor: Gualtiero Giori

Patent number: 4051781Abstract: An ink roller cartridge having an ink roller rotatably mounted therewithin is formed with an opening through which the ink roller is engageable with a printing type drum when the cartridge is mounted on a printer body. The cartridge is provided with a lid to close the opening. A knob is provided on the outer periphery of the ink roller cartridge to facilitate the mounting and dismounting of the cartridge.Type: GrantFiled: May 3, 1976Date of Patent: October 4, 1977Assignees: Canon Kabushiki Kaisha, Canon Denshi Kabushiki KaishaInventor: Tatsuo Nishikawa

Patent number: 4044677Abstract: There is disclosed a printing apparatus having a print head and an inking mechanism for inking the print head. The inking mechanism comprises an ink roller, an inker body or carrier for the ink roller and structure for movably mounting the inker body. The ink roller is rotatably mounted to the inker body by mounting means including a pair of mounting members. The inker body has a pair of undercut slots and the mounting members have respective flanges received in the slots. Each mounting member is shown to have a resilient member or finger engageable with a respective shoulder on the inker body to lock the mounting member to the inker body. The inking mechanism has means for preventing its disconnection from the printing apparatus while the inking mechanism is in cooperation with the print head, but the inking mechanism can be removed and replaced with a new inking mechanism having a new ink roller while the inking mechanism is out of cooperation with the print head.Type: GrantFiled: August 13, 1975Date of Patent: August 30, 1977Assignee: Monarch Marking Systems, Inc.Inventor: Paul H. Hamisch, Jr.

Patent number: 4022124Abstract: A machine for printing letters, numbers, symbols and the like on banding or other flexible material of extended length includes a drive wheel and a printing wheel, as well as pressure rollers for pressing the banding against the two wheels. The drive wheel is driven by the banding as the banding is drawn through the machine, and the printing wheel is connected to the drive wheel through a belt such that the two wheels have the same peripheral velocity. Thus, the printing wheel, which has raised characters around its periphery, rotates as the banding passes over it. The raised characters of the printing wheel further pass over the periphery of an ink transfer wheel, all but a small segment of which is contained within a sealed case of an inking unit. The surface of the ink transfer wheel is pitted, and where that wheel emerges from the case, seals are provided to form a vapor barrier which isolates the interior of the case from the surrounding atmosphere.Type: GrantFiled: October 29, 1975Date of Patent: May 10, 1977Assignee: McKenna Equipment Company Inc.Inventor: David S. Knudsen
