  • Publication number: 20130113156
    Abstract: In a sheet feeder apparatus, a feeder mechanism for picking up sheets from a stack of sheets of a material includes a support bar, at least one pickup head, and an adjuster. The support bar includes cylindrical ends and an intermediate portion between the cylindrical ends. The cylindrical ends are configured to pivotally couple to control arms of the sheet feeder apparatus. The pickup heads are coupled to the intermediate portion of the support bar and an adjuster is coupled to the support bar at one of the cylindrical ends. The adjuster includes a bracket coupled to the intermediate portion of the support bar, a pivot arm selectively pivotable about the cylindrical end of the support bar, and an adjustment mechanism coupled between the bracket and the pivot arm. The adjustment mechanism pivots the support bar relative to the pivot arm to thereby tilt the pickup heads.

  • Patent number: 6272985
    Abstract: A link mechanism is provided for setting and maintaining a minimum spacial distance between a blanket cylinder and a plate cylinder of a rotary printing press. The link mechanism includes a first link arm that is rotatably mounted on an axle of the blanket cylinder at one of the blanket cylinder. A second link arm rotatably is mounted on an axle of the plate cylinder. The first link arm and the second link arm are pivotably connected to each other for single axis pivoting about a point offset to one side of an imaginary line drawn through centers of the plate cylinder axle and the blanket cylinder axle. An adjustment mechanism is positioned between the first and second link arms on projections offset to the other side of the imaginary line so that the set minimum spacial distance between the plate cylinder axles and the blanket cylinder axle can be adjustably set and maintained throughout impression rotation of the rotary printing press.

  • Patent number: 5865116
    Abstract: An apparatus for continuously providing dampening fluid to a plate cylinder of a lithographic printing press includes a frame operatively connected to the printing press. A dampening fluid reservoir is attached. A pan roller is rotatably mounted in the frame and is disposed in contact with dampening fluid in the dampening fluid reservoir. A transfer roller set tangentially contacts and is parallel to the pan roller. The transfer roller is rotated by friction from the pan roller which is driven at a rotation speed proportional to the speed of the plate cylinder. An ink receptive oscillating roller having a resiliently compressible surface is tangentially contacting and parallel to the transfer roller. The oscillating roller is gear driven at a rotational speed proportional to the speed of the plate cylinder.

  • Patent number: 5022322
    Abstract: A metering roller engages a liquid pickup roller to meter liquid through the nip therebetween. A stationary shaft through the middle of the metering roller carries spaced bearings at adjustable locations engaging the inside of the roller. A fulcrum is provided to support the stationary shaft near each end thereof. A forcing cam spaced inwardly from each fulcrum has an adjustable pivot point, and is forced into engagement with the stationary shaft to produce bending moments in the shaft transmitted to the roller through the bearings to bias the metering roller toward the metering nip. The position of each fulcrum may be adjusted in two directions, and the magnitude of the bending moments adjusted by moving the forcing cam pivot point.

  • Patent number: 4949637
    Abstract: A dampening system for a lithographic press in which a train of rollers delivers dampening fluid from a dampening fluid pan to the plate cylinder of the lithographic press is provided. The train of rollers comprises a hard rubber pan roller, a rubber transfer roller of medium hardness, and a relatively soft rubber water form roller. The transfer roller is mounted in parallel relation to the pan roller and can be moved towards or away from the pan roller in order to vary the pressure therebetween and to thus meter the dampening fluid delivered to the plate cylinder. Dampening fluid is conveyed from the pan roller, to the transfer roller, to the water form roller, and finally to the plate cylinder. The pan roller and water form roller are driven at the surface speed of the plate cylinder through a gear train.

  • Patent number: 3985073
    Abstract: A numbering head assembly for use with a printing press and for printing consecutive numbers on material printed in the press such as invoices, tickets, etc. The numbering head assembly includes a rotating numbering head for printing consecutive numbers on each piece of paper passed through the printing press and means for supporting the rotatable numbering head in a position where it may be forced into printing engagement with the impression cylinder of the printing press. The assembly also provides means to index the numbering head once for each piece of paper printed so that a consecutive number is printed on each paper and means to selectively actuate the numbering head so that the head is brought into printing engagement with the impression cylinder only when paper is passed through the printing press.
