  • Patent number: 6120015
    Abstract: An on-line sheet hole punching system for punching holes in sheets outputted by a printing system, to eliminate pre-punched sheets, with a common sheet entrance path, two separate but closely vertically superposed sheet paths, a gating system alternately gating the unpunched sheets into one of said two separate sheet paths having respective separate, but shared components, sheet punching stations with commonly reciprocally vertically driven sheet punches. The sheets are alternatingly stopped and the desired hole patterns are alternatingly punched, and the sheets ejected, in the two separate sheet paths, individually punched, or punched as stacked sets. The separately punched sheets may be remerged in a common output path. Skipped pitches or other printing or output interruptions are avoided. A common vacuum system for waste paper punch-outs collection may service both punching stations.

  • Patent number: 5934662
    Abstract: A bottom sheet feeding system for feeding individual image substrate sheets for reproduction apparatus out from under a stack of such sheets by intermittently feeding the bottom sheet out from under the overlying stack of sheets in a sheet stacking tray with a bottom sheet feeder, which may be electrostatic, while that stack of sheets is intermittently at least partially levitated relative to the bottom sheet to substantially reduce the gravitational force of the overlying stack of sheets normally bearing down on the bottom sheet to resist the separation and feeding of the bottom sheet out from under the rest of the stack. This intermittent stack levitation may be accomplished by appropriate cyclical transducer system forces applied to the bottom of the stacking tray at a frequency coordinated with intermittent feeding of the bottom sheet out from under the stack.

  • Patent number: 5937258
    Abstract: A paper conditioner to control image dependent curl which uses one or more counter-rotating transfer rollers which are initially spaced from their respective back-up rollers in the intercopy gap, and which come together as the lead edge enters the nip area, and separates when the trail edge is about to pass. This permits the rollers to have a less demanding runout tolerance by bringing the rollers together when the sheet is in the nip, and then articulating the rollers apart in the intercopy gap.

  • Patent number: 5915149
    Abstract: A ball-on-belt transport includes a belt with a steel ball positioned on top of the belt and a magnet on the back side of the belt with the ball forming a nip with the belt to provide necessary normal force against a conveyed sheet and thereby allowing easy lateral pulling of sheets in clearing jams from the nip. Alternatively, a steel ball is retained while in contact with a belt to apply a normal force to a sheet on the belt equal to the weight of the steel ball. The ball is encased in a housing that is surrounded by a solenoid coil such that when current is applied to the coil, it acts as a solenoid and raises the ball off the belt surface and thus releases the nip pressure.

  • Patent number: 5899449
    Abstract: A top vacuum corrugation feeder includes articulating suction fingers to assist in raising the top sheet of a stack of sheets to the feedhead of the vacuum corrugation feeder. The suction fingers are rotated down from their interleaved position between feed belts to contact the top sheet in the sheet stack and raises the top sheet to the feed belts. As a result, the feeder can handle heavy sheets, curled sheets, and sheets which are edge welded.
