Abstract:
A system for folding sheet material (248), including a fold blade (104), a fold roller (106), and drive means (112) for moving at least one of the fold blade (104) and the fold roller (106) along a first path into operative communication with one another, where the operative communication causes displacement of the fold roller (106) along a longitudinal axis of the fold blade (104).
Abstract:
A hole-punching process for a sheet-wise booklet maker, including a hole punching device (303), a clamp (311), and a drive system (309). While a folded booklet sheet (319) is being held stationary on its leading side, the drive system (309) 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. By comparing provided position information with a correct hole location determined from the sheet information, the drive system advances the folded edge of the sheet to a position within the punching device where the punch creates a hole.
Abstract:
A system for folding sheet material (248) is provided, including a fold blade (104), two fold components (106a, 106b) biased toward one another, and first drive means (112) for moving at least one of the fold blade (104) and the two fold components (106a, 106b) to position the fold blade (104) between the two fold components (106a, 106b) and thereby displace the two components (106a, 106b) away from one another, where the two fold components (106a, 106b) are mounted on different support elements (142).
Abstract:
Method and apparatus useful for eight-level halftone thermal ink jet printing by printing with droplets of ink with volumes weighted in a binary sequence. Three binary-weighted drop generators (50, 52, 54) which are fired in sequence are useful in an eight-level, three color printing process and additionally may be employed with a clear ink vehicle drop generator (60) in order to reduce optical density of single small dots in a given pixel area to thereby reduce grainyness. This method and apparatus are also adapted for three color number printing with a chosen number of rows and columns of binary-weighted drop generators, (84, 86, 88) including untoned vehicle if desired, in order to achieve color printing of pixels having desired color and optical density.
Abstract:
A probabilistic input-output system is used to classify media (18) in printer applications. The probabilistic input-output system uses at least two input parameters to generate an output that has a joint dependency on the input parameters. The input parameters are associated with image-related measurements acquired from imaging (26, 28 and 32) textural features that are characteristic of the different classes (types and/or groups) of possible media. The output is a best match in a correlation between stored reference information (62) and information that is specific to an unknown medium of interest. Cluster-weighted modeling techniques are used for generating highly accurate classification results. Within the imaging process, grazing angle illumination (i.e., introducing light at an angle of at least 45 degrees to the normal of the surface being imaged) provides sufficient contrasts for distinguishing the structural features (e.g., paper fibers) of the unknown medium, but non-grazing illumination may be used when specular measurements are to be obtained.

Abstract:
A system for folding (248), including a fold blade (104), two fold rollers (106a, 106b) biased away from each other, an adjusting member (172) which alters a distance between the two fold rollers (106a, 106b), and first drive means (112) for moving at least one of the fold blade (104) and the two fold rollers (106a, 106b) along a first parth to position the fold blade (104) between the two fold rollers (106a, 106b).
Abstract:
The system and method for binding documents as described creates documents having features such as tabs, finger indexes, tear-out cards, and windows. These features are desirable for both their appearance and functionality and are easily added to a document during sheet-by-sheet processing. A sheet-wise binding system includes a sheet transport path for transporting a plurality of printed sheets in a sheet-wise manner and a punch a feature into at least one of the sheets traveling through the sheet transport path. A stacking system is provided for stacking the punched and unpunched sheets and a binding system for binding the stacked sheets is used to form a finished document. A controller is programed to control the sheet transport path and the punch to create the features in selected sheets and at selected locations in the sheets according to the punch schedule.
