Abstract: An apparatus and article for cutting print media associated with a printing process. A media cutting logic-controlled head is incorporated into printing hardware. The cutting head is provided with a plurality of cutting devices that may be implemented in the form of cutting pins. Control logic is provided to individually control an extension or actuation of each of the cutting devices. Multiple cutting devices may be simultaneously extended and retracted or activated and deactivated, to cut the media at multiple locations. The cutting head can be integrated with any of existing printers transforming a printer into a media cutting device capable of cutting two-dimensional complex shapes at the full line speed without requiring change in speed or reversal of the media at any point.

Abstract: A sheet punching device that cuts holes in a sheet while punches are entering die holes, in which a plurality of punch trains along each of which a plurality of punches are aligned on a rotating shaft in parallel with the rotating shaft are disposed in the rotation direction of the rotating shaft, and the die holes are disposed in correspondence with the punches of the punch trains.

Abstract: A method for creating multiple punch holes during a finishing process of paper sheets and other sheet materials. A highlight of the present invention is the ability to select between at least two configurations of punch holes automatically, without manual adjustment, and “on-the-fly” without interruption of the sheet or paper flow. The perforation method utilizes two rotatable punches set at different angles such that when one intersects the sheet path, the other clears the sheet path. The speed of rotation is controlled such that the non-selected punch intersects the sheet path in a space between pitches.

Abstract: A sheet punching device cuts holes in a sheet while punches are entering die holes. The sheet punching device includes, a plurality of punch trains, each of which includes a plurality of the punches axially aligned on a rotating shaft and projecting in a radial direction of the. The plurality of punch trains is disposed in a rotation direction of the rotating shaft relative to one another, and the die holes are disposed in correspondence with the plurality of punches. One of the plurality of punch trains is selectively used in cutting holes in the sheet.

Abstract: Rectangular drawings of standard dimensions or formats can be automatically cut out of a continuous paper or plastic web (1) by a transverse cutter (9) and a plurality of longitudinal cutters (26), as directed by coding (20) on the edge of the web. The cut-off strips (23) of scrap made by transverse cutter (9) are directed away by a movable deflector (13). Additional deflectors (62) are provided downstream, in web motion direction D, of the longitudinal cutters (26) and serve to separate the scraps (23, 25) produced by the longitudinal cutters from the drawing forms (A0-A4) which have been trimmed on all four sides. Thus, manual separation of the drawings from the surrounding scrap is obviated.

Abstract: A dispenser for cards which are withdrawn by customers at the entrance of a parking lot has a housing for a supply of coherent cards which are transported seriatim by advancing rolls toward an outlet opening for withdrawal by customers. On its way toward the outlet opening, each card is provided with legible information by a matrix printer which can apply such information in response to a signal from a computer while the card is in motion. The thus imprinted card then advances between the matrix and the perforating tool of a punching apparatus which applies one or more holes while the card is in motion. The matrix and the tool are mounted on a plate which is secured to a fixed bracket by a first parallel motion mechanism so that it can move in and counter to the direction of movement of the card between the tool and the martrix. The plate is pivotable about a fixed axis by an oscillating crank gear so that the tool moves along an arcuate path to which the adjacent card is tangential.

Abstract: A maximum web speed monitor for limiting the speed of a moving web which is cut into sheets by a knife such as a rotary knife. A digital cut-off control provides separate signals indicative of the web speed and the length of sheets into which the web is cut by the knife. A digital integrator repetitively provides a sample signal indicative of the actual speed of the web based on a preselected sampling interval. Information representative of maximum permissible web speed as a function of sheet length is stored in a PROM. The web speed is prevented from exceeding a maximum permissible speed as a function of the maximum permissible web speed information and the sample signal.

Abstract: A rotary perforating apparatus for forming the guide perforations in photographic film, wherein the mechanism which controls the movements of the punch carrier arms comprises a control disc which rotates eccentrically with respect to a film-supporting wheel, and wherein the punch carrier arms are connected to said control disc through control arms which may perform a spacial swinging movement, thereby to provide a mechanism which is little subject to wear, and wherein standard ball bearings and ball joints may be used.
