In an example, a computer-implemented method includes generating test data that is configured to be identified as data of interest at one or more visibility points in a network having a plurality of network routes. The method also includes injecting the test data into each network route of the plurality of network routes at a location upstream from the one or more visibility points, and determining, for each network route through which the test data travels, whether the test data is identified at the one or more visibility points. The method also includes outputting, for each network route through which the test data travels, data that indicates whether the test data is identified at the one or more visibility points as data of interest.

A sheet processing apparatus includes a rotating member, a switching unit, and a pressing unit. The rotating member is rotatable and has a facing portion that faces a fold section of a sheet. The rotating member rotates so as to switch the facing portion to another facing portion. Each facing portion is provided with a protrusion. A set position of the protrusion in an axial direction varies from facing portion to facing portion. The switching unit rotates the rotating member so as to switch the facing portion that faces the fold section. The pressing unit presses the protrusion of the facing portion against the fold section.

A creasing device is provided that includes a counter-rotating male drum and female drum. The male drum carries a conventional creasing ring with a central rib flanked by shoulders. The female drum comprises a central channel aligned with the creasing rib on the male drum; and a pair of projecting lateral ribs on each side of the central channel that are aligned with the shoulders on the male drum. The lateral ribs press a sheet of the card or paper stock against the shoulders of the creasing ring to better define the edges of the crease and to reduce the tendency of a printed coating on the stock to crack during subsequent folding. The pair of lateral ribs may be provided by a pair of inserts. Alternatively, both ribs and the central channel may be provided by a single insert.

A creasing device includes a frame with a substantially horizontal support surface for supporting an article to be creased; a movable tool; and a stationary tool, the latter comprising a stationary member and at least one displaceable member whose height relative to the stationary member can be adjusted. A first actuator moves the movable tool toward the stationary tool and interacts with opposite faces of the article, and a second actuator translates the displaceable member between a first end position in which interacts with the movable tool and a second end position in which it cannot interact with the movable tool. Guide means associated with the stationary tool guides the displaceable member between the first end position and the second end position. The guide means are have a curvilinear path contained in a plane substantially perpendicular to the support surface.

A machine produces twisted paper for loose file packaging. The machine includes at least one auger to reduce a dimension, such as diameter, of paper as it is pulled from a roll. The material moves past the auger into a twisting assembly wherein the paper is twisted or rotated about a longitudinal axis of the machine inside a pipe or tube. The pipe or tube includes a cutout or interruption in the sidewall within which a wheel resides. The wheel grasps and advances the paper through the twisting assembly as it rotates. As the paper leaves the twisting assembly it is pulled or otherwise fed through an exist region and is cut into segments of small twisted pieces of paper. The twisted segments of paper are of suitable size for use as loose fill packaging.

In a device for double folding leaves, the device is provided with two conveyor belts that are located against one another such that leaves can be clasped between the conveyor belts with the exception of a strip that protrudes between the conveyor belts, whereby the conveyor belts are aligned with respect to one another along the side of the strip and with two or more folding elements along the conveyor belts that can fold the aforementioned strip, whereby the device. is equipped such that leaves are guided with their strip alongside the folding elements by the driving of the conveyor belts, whereby at least one folding element folds the strip in one direction and at least one folding element folds the strip in the other direction.

A sheet processing apparatus includes a pressing unit and a shifting unit. The pressing unit has a protrusion and presses the protrusion against a fold section of a sheet. The fold section extends in one direction. The shifting unit moves at least one of the protrusion of the pressing unit and the sheet so as to shift a pressing position, at which the fold section is pressed by the protrusion, in the one direction or in a direction opposite to the one direction.
