Patent number: 4863086Abstract: A device for supplying a machine working on a web of material in a stopped position particularly for a flat cutting press and in the vicinity of an intake roller and downstream thereof, in the direction of advance of the web, the device includes an oscillating roller. This roller is mounted for rotation on a support adapted to oscillate about the axis of the intake roller. The oscillating roller is driven in rotation on itself from the intake roller, via a transmission mechanism in such a manner that the peripheral speed of the oscillating roller is identical to that of the web of material winding around part of the periphery of this oscillating roller. A mechanism is provided for provoking a movement of oscillation of the support and of the roller that is bears.Type: GrantFiled: July 19, 1988Date of Patent: September 5, 1989Assignee: Machines Chambon S.A.Inventor: Michael Armelin

Patent number: 4643130Abstract: Apparatus for forming matchbox skillets from pre-printed sheets, each sheet having a plurality of rows of matchbox blanks printed thereon. The apparatus includes a sheet feeder for storing pre-printed sheets and removing the sheets one-by-one. The sheets are fed to a gravure printing machine, which applies stripes of striking compound material to predetermined areas of the sheets as they pass therethrough. A conveyor is provided for conveying the sheets from the sheet feeder to the gravure printing machine. After leaving the gravure printing machine the stripes of striking compound material are dried in a radio frequency drier. The sheets are then cut into matchbox blanks by cutting machines. The gravure printing machine has an upper engraving roller, a lower pressure roller, and means for feeding the sheets between the two rollers so that the stripes are printed on the upper surface of the sheets in register with the matchbox blanks.Type: GrantFiled: February 2, 1984Date of Patent: February 17, 1987Assignee: Machines Chambon S.A.Inventors: Jeremy C.

Patent number: 4211167Abstract: The present invention relates to an inking device for printing with greasy ink, said device being characterized in that it comprises, downstream of the zone of contact of the inking roller and the plate or photogravure cylinder, a second rod parallel to the inking roller, pressed under strong pressure against the soft surface layer of said roller and forming a barrier only against the dampening liquid, while allowing all the residual film of ink remaining on the periphery of the inking roller to pass and thus return to the mass of ink in the inking device. This invention is more particularly applicable in printing machines employing greasy ink, such as offset or typo printers.Type: GrantFiled: July 12, 1978Date of Patent: July 8, 1980Assignee: Machines ChambonInventor: Louis G.

Patent number: 4141293Abstract: A rotary multi-color printing machine comprises a frame and a plurality of printing units each of which prints in a different color on sheet material passing through the machine. The printing units are mounted one above another in the frame so that the sheet material can pass successively through the printing units. Each printing unit comprises a counter-pressure roll, a blanket roll, a plate roll and an inking roll, the axes of the rolls being parallel. The plate roll and the blanket roll of each printing unit are rotatably mounted in a support. The counter pressure roll of each printing unit is rotatably mounted in the frame on one side of the support, and the inking roll of each printing unit is rotatably mounted in the frame on the other side of the support. The support is slidable relative to the frame in a direction which is horizontal and axial relative to the rolls.Type: GrantFiled: May 3, 1977Date of Patent: February 27, 1979Assignee: Machines ChambonInventor: Louis G.

Patent number: 4129065Abstract: A method of grooving sheet material along a line about which the material is subsequently to be folded comprises the step of forming, along said line, an impression. The impression forms a groove on one side of the material, the groove being intended to form the outer face of the edge of the fold when the material has been folded. The impression also forms, on the other side of the material, a corresponding bead which is intended to be located on the inside of the fold. Two parallel and opposite lines of elongate depressions are formed in the bead during the formation of the impression, the lines of depressions being formed one on each side of the central longitudinal axis of the bead. Each depression is constituted a portion of material which is of reduced thickness and which creates a localized zone of reduced strength.Type: GrantFiled: December 29, 1976Date of Patent: December 12, 1978Assignee: Machines ChambonInventor: Louis G.
