Disclosed is a guiding device having a guide roller that is rotatable about a roller axis and that has an exterior guide surface extending in a circumferential direction about the roller axis, wherein the guide roller includes a plurality of roller segments juxtaposed in an axial direction along the roller axis for forming the exterior guide surface, wherein the plurality of roller segments are movable relative to each other to enable the guide roller to be positioned in a maximum bend state in which the roller axis extends along an arc, wherein the plurality of roller segments are interlocked to rotate together about the roller axis in a maximum bend state, wherein the plurality of roller segments extend over an arc length along the arc of the roller axis, wherein the arc length is at least ninety degrees in the maximum bend state.

An image forming apparatus, comprising a conveyance path configured to convey an image receiving medium; a fixing device configured to fix an image formed on the image receiving medium; a first roller arranged at the downstream side of a conveyance direction of the image receiving medium with respect to the fixing device, the first roller comprising an axis; a second roller configured to face the first roller and an end thereof of which protrudes towards a central part of the conveyance path with respect to an end of the first roller at the central part of the conveyance path in a first direction substantially parallel to the axis; and a protrusion arranged at the second roller side to protrude towards the first roller side from the second roller side and a protruding amount of which is greater than that of the second roller.

Methods and systems for preventing wrinkles in a web passing through an accumulator. The accumulator comprises a plurality of rollers including at least one roller having an axis of revolution movable toward and away from the axis of revolution of another roller to release and store varying amounts of the web. At least one of the rollers has a nominally flat outer surface and at least one of the rollers has a profiled outer surface.

An apparatus includes a bi-modal roller configured to rotate about a longitudinal axis of the bi-modal roller. The bi-modal roller includes two ends and a rolling outer surface. The rolling outer surface is divided into a convex portion and concave portion. The concave portion includes at least one concave curve extending longitudinally between the two ends. The concave portion is configured to, when a film physically contacts the concave portion, affect translation of the film in response to a stick condition or a slip condition. The convex portion includes at least one convex curve extending longitudinally between the two ends. The convex portion is configured to, when the film physically contacts the convex portion, affect translation of the film in response to a stick condition or a slip condition.

A sheet transport device includes a transport path along which a sheet is transported in one direction, the sheet being transported with a corner at a leading end of the sheet being located on a first lateral side of the path, a sheet rotating section that rotates the sheet so as to increase an angle of the sheet and so as to orient the leading end, a sheet moving section that moves the sheet toward the first lateral side, and plural sheet butting portions that are arranged side-by-side in the one direction, on the first lateral side, the sheet butting portions allowing the moved sheet to be butted thereagainst to orient the sheet in the one direction. When the sheet is butted against the sheet butting portions to be oriented in the one direction, the corner is located at a position where no sheet butting portions are provided.

Disclosed is a guiding device having a guide roller that is rotatable about a roller axis and that has an exterior guide surface extending in a circumferential direction about the roller axis, wherein the guide roller includes a plurality of roller segments juxtaposed in an axial direction along the roller axis for forming the exterior guide surface, wherein the plurality of roller segments are movable relative to each other to enable the guide roller to be positioned in a maximum bend state in which the roller axis extends along an arc, wherein the plurality of roller segments are interlocked to rotate together about the roller axis in a maximum bend state, wherein the plurality of roller segments extend over an arc length along the arc of the roller axis, wherein the arc length is at least ninety degrees in the maximum bend state.

A yarn deflection unit for a textile machine, having a housing comprising a curved wall section for forming a radially outer wall section of a curved yarn deflection channel. The solution proposed by the invention is distinguished in that the curved wall section has a yarn guiding groove extending along the curvature for receiving and guiding a yarn.

A particle collection cartridge includes a first side having a particle intake region, a second side having a particle inspection region, supply and uptake reels, a tape guide, tape, a first pin, and a second pin. The tape is wound about the supply reel, extends to the first pin, across the tape guide, to the second pin, and terminates at the uptake reel. The tape includes an adhesive surface to collect particles entering the particle intake region. The first and second pins are fixed to not rotate.

A line member connection device which applies an adhesive tape includes: a supply reel which supplies the adhesive tape; a cutter which cuts the adhesive tape drawn from the supply reel; and an intermediate roller via which the adhesive tape drawn from the supply reel is directed to the cutter, the intermediate roller being disposed between the supply reel and the cutter, wherein in cross section taken along a rotation axis of the intermediate roller, a surface of the first roller which supports the adhesive tape is shaped to have a straight section parallel to the rotation axis, and a first inclined section inclined relative to the rotation axis.

The ink is discharged to the printing medium F located in the first range R1 from the upstream end Wuu of the upstream winding part Wu where the support roller 26a and the printing medium F are in contact to the downstream end Wdd of the downstream winding part Wd where the support roller 26e and the printing medium F are in contact. The support rollers 26a, 26e located on both ends of the first range R1 are in contact with the printing medium F on the peripheral surfaces 261 having such a concave shape to increase the diameter from the center toward the ends in the width direction Y (axial direction). This causes these support rollers 26a, 26e to suppress the formation of wrinkles in the first range R1 where the ink is discharged.
