  • Patent number: 6673002
    Abstract: A system for folding sheet material, including a fold blade, a fold roller, and a driver for moving at least one of the fold blade and the fold roller along a first path into operative communication with one another. The operative communication causes displacement of the fold roller along a longitudinal axis of the fold blade.

  • Patent number: 6641345
    Abstract: Systems and methods are described for increasing the binding strength of a bound text body by increasing the spinal surface area exposed for adhesive penetration greater than an area corresponding to the product of the sheet height dimension, the sheet thickness dimension and the number of sheets. In one aspect, sheet-wise conditioning of the binding area is performed prior to the application of adhesive to increase the bond area between sheets of the text body. In another aspect, the spinal surface area exposed for adhesive penetration is increased as adhesive is applied.

  • Publication number: 20030194253
    Abstract: Systems and methods for duplex printing of print sheets are described. In one aspect, a duplex module is configured so that print sheets may be controllably and reliably re-introduced into a print module in an orientation that is suitable for marking the second side of the print sheet without requiring a support structure that spans the entire width of the print sheet. In large format printing applications, this feature avoids large and heavy support structures, such as feed rollers, that otherwise would be needed to support the print sheets, as well as their own weight. In this way, a printing apparatus may provide duplex printing functionality with a structure that has a relatively light weight and a relatively small overall footprint.

  • Patent number: 6632061
    Abstract: A trimming apparatus for a booklet maker is described which provides a compact and low cost booklet maker for desktop publishing. The booklet maker includes a sheet receiving tray for receiving a stack of sheets to be stapled into a booklet, a stapler unit arranged to staple the stack of sheets, and a trimming system for trimming the sheets in a sheet wise manner. The trimming system includes first and second pick and separate mechanisms arranged to separate each of the sheets in the stack of sheets and first and second cutters arranged to cut each of the separated sheets after the have been separated by the first and second pick and separate mechanisms. A controller positions the sheets and controls the trimming system to cut each of the separated sheets at a location determined based on a trimming schedule. The trimming schedule varies the position of the cut depending on a position of the sheet in the booklet and a thickness of the sheets.

  • Patent number: 6619900
    Abstract: Systems and methods for binding a text body are described. A multi-function sheet binder is configured to heat a preformed solid hot melt adhesive to a melting temperature, form the melted adhesive by pressing the melted adhesive into a spine of a text body and folding down edges of the melted adhesive into contact with the text body, and actively cool the formed adhesive. A spot heater is configured to heat one or more localized areas of a solid hot melt adhesive to a temperature sufficient to tack the hot melt adhesive to a text body spine. An adhesive former is configured to press a localized region of a preformed heated solid hot melt adhesive into a spine of a text body and to fold down edge regions of the preformed solid hot melt adhesive into contact with the text body.

  • Publication number: 20020141849
    Abstract: A hole-punching process for a sheet-wise booklet maker, including a hole punching device, a clamp, and a drive system. While a folded booklet sheet is being held stationary on its leading side, the drive system advances the trailing side of the folded sheet, thereby forcing the folded edge of the sheet into a hole punching device. The operation of the drive system is based on sheet information associated with the folded sheet, which includes information such as the order number of the folded sheet within the to-be-assembled booklet and the accumulated thickness of other sheets to be positioned within the folded sheet. Position information is also determined, indicating the instantaneous distance between the folded edge of the sheet with a hole punch in the hole punching device.
