Publication number: 20230391574Abstract: This invention provides web-cutting mechanism that can be mounted in line at an appropriate location between the web-handling peripheral (printer) and a web roll. The cutting mechanism operates before the available storage in the winder festoon has been exhausted, and decouples the roll's energy from the web. The cutting mechanism can employ a blade that is drawn through the web solely by the movement of the web itself. The blade is mounted at a (e.g.) 45-degree angle to web travel, causing it to be pulled through the web. A negator spring assembly and associated cable drives the blade into the side edge of the web when a slide-mounted blade shuttle assembly is released by a latching pawl of a solenoid assembly. The solenoid is triggered by a signal indicating an emergency stop condition, such as an upstream jam.Type: ApplicationFiled: May 31, 2023Publication date: December 7, 2023Inventors: Stephen E.

Patent number: 8033624Abstract: This invention provides a system and method for printing continuous web and feeding ink to printing pens (or cartridges) that employs an array of interleaved ink-jet pens that are arranged to receive bulk ink through a manifold. The manifold and pens are mounted on a fixed array suspended over the web feed path. The manifold includes a plurality of self-sealing quick-disconnect couplings that each serve a discrete ink-jet pen. The pens lay down ink in a registered manner across the full width of the web. The pens are organized into two parallel, multi-pen arrays that are each diagonally oriented with respect to the feed direction. The feed path allows for duplex printing with a second web-side's array located on a lower level of the device, generally beneath the first-side's array. Duplex printing is facilitated due to its inherent length of the feed path. The printed part of the web is free of contact over predetermined lengths that ensure sufficient time for the drying of ink.Type: GrantFiled: July 24, 2007Date of Patent: October 11, 2011Assignee: Lasermax Roll Systems, Inc.Inventors: Stephen E. Silva, Peter J. Wood, John M. Fiske, Cadman E. Rozea

Patent number: 6357349Abstract: A device for feeding web material to a printer that is adapted to accept web from an external roll, adequately align the web with the printer and properly tension the web as it passes through the printer. The infeed device includes a pair of parallel guide rods spaced sufficiently apart to allow passage of the web there between. A pair of edge guides, attached to the parallel guide rods define the web path there through. A spring-loaded pressure pad acts in combination with a smooth metal shoe to tension the web. Further tension is applied to the web as it passes a curved smooth metal surface, just prior to entering the printer. The infeed device allows a wide variety of web materials and web thicknesses to be tensioned and fed into the printer.Type: GrantFiled: July 5, 2000Date of Patent: March 19, 2002Assignee: Roll Systems, Inc.Inventors: Kevin W.

Patent number: 6095391Abstract: A method and apparatus is presented for stabilizing a free loop of web material between two web handling devices. The present invention employs fans or other forced air sources, directed toward the inner surface of the free loop, to maintain a stable free loop shape, thereby permitting simplified web handling and more accurate control of the web feeding or web take-up rate.Type: GrantFiled: August 4, 1998Date of Patent: August 1, 2000Assignee: Roll Systems, Inc.Inventors: John Mayo Fiske, John Fairhurst, Stephen E.

Patent number: 5558318Abstract: A system for conveying folded web and forming discrete stacks of folded web comprising a conveyor that receives a stack of folded output web from a web folder and separator. The conveyor drives the web from an upstream end, adjacent the web folder and separator, to a downstream end. A supporting surface, which can comprise a plurality of pivoting rails biased by a spring, selectively supports the web remote from and off of the conveyor so that a compressed stack can be formed adjacent the folder and separator. At selected times, the stack is moved by the supporting surface into communication with the folder and separator so that it can be conveyed downstream. An elevator platform can be located at the downstream location for receiving successive stacks thereon. The elevator ascends and descends so that the tops of the successive stacks are aligned with the conveyor for receipt of a further stack thereon.Type: GrantFiled: March 29, 1994Date of Patent: September 24, 1996Assignee: Roll Systems, Inc.Inventors: H.
