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.

A method, apparatus and program product may evaluate a packaging material to determine various metrics associated with the packaging material. An apparatus may be used to sense flaws in packaging material, and in some instances, to accommodate such flaws by temporarily increasing a dispense rate of a packaging material dispenser.

A printer includes a transport unit that transports continuous paper, a medium support unit in which a support surface that is capable of supporting continuous paper that is transported by a transport unit, and first concave sections, which are indented from the support surface, are formed, and an image capture unit, which is disposed on a lower side of the support surface, and which captures an image of a lower surface of the continuous paper.

A device and a method for manufacturing a corrugated cardboard include a second paper splicing device that splices a succeeding sheet to a preceding sheet, which are a second sheet; a third paper splicing device that splices a succeeding sheet to a preceding sheet, which are a third sheet; a single-faced web splice detection unit that detects a third paper splice part of the third sheet, based on a thickness of a single-faced web in which the second sheet and the third sheet are attached to each another; and a control device that controls at least one of the paper splicing times of the second paper splicing device and the third paper splicing device so that the third paper splice part is placed on a downstream side of a second paper splice part of the second sheet in a sheet conveyance direction, at an attachment position of the second sheet and the third sheet.

An antistatic device for reducing electrostatic charges on moving material webs may include an active positive electrode assembly having a plurality of active individual positive electrodes electrically connected to a positive high voltage source. The device may include an active negative electrode assembly having a plurality of active negative electrodes electrically connected to a negative high voltage source. A sensor system may be included for detecting a polarity of a neutralising current between the material web and the antistatic device during operation of the antistatic device, and a controller for controlling the high voltage sources. The controller may be coupled to the sensor system and may be at least one of programmed and configured to one of active or leave activated the high voltage source required in each case and one of deactivate and leave deactivated the high voltage source not required in each case in response to the detected polarity of the neutralising current.

A printer includes an image forming station; a first media transport path arranged to convey printed media from the image forming station to an output port; a second media transport path branching off from the first media transport path and arranged to convey printed media to a reject port; a switch for directing printed media into the second media transport path; an image inspection device for inspecting images printed onto the media; and a decision unit arranged to decide, on the basis of an inspection result obtained from the image inspection device, whether a printed image shall be rejected, and arranged to control the switch. The printer is a roll-to-sheet printer having a roll from which the media are supplied into the first media support path in the form of an endless web. The printer includes a cutting device for cutting the web; and the decision unit is arranged to cause a reversal of the transport direction of the media in the first media transport path, thereby to move an edge of the printed media to the position of the switch.
