A conveying device includes a sheet conveyor configured to convey a medium in a conveyance direction of the medium, a sheet winder including a winding roller and a winding motor, and circuitry to control the sheet conveyor and the sheet winder. The circuitry is configured to convey the medium intermittently while repeating: causing the sheet conveyor and the sheet winder to convey the loosened medium by a predetermined conveyance amount; rotating the winding motor in a normal direction by a predetermined torque according to an outer winding diameter of the medium to apply a predetermined tension force to the medium; and rotating the winding motor in a reverse direction to loosen the medium by a predetermined slack amount. The circuitry is configured to determine the predetermined tension force according to the width of the medium intersecting with the conveyance direction of the medium.

Systems for providing efficient manufacturing of paper, sheet, and/or box products of varying size and structure, often with pre-applied print (“pre-print”), are provided herein. Efficient customer ordering/tracking, job aggregation, print imposition, corrugator planning, and tracking and adjustments throughout the manufacturing process are contemplated. A reel editor is configured to edit the roll based on waste and/or errors that occurred during various manufacturing processes (e.g., during printing). A control plan defining what is on each roll of printed web product may be updated after editing. Depending on the configuration, the reel editor may be integrated with various manufacturing components. The reel editor may be configured to determine if there is enough waste on the roll to even making editing worthwhile, such as based on desired quality of the images, customer requirements, different price points, among other possible factors.

The rewinding machine (1) comprises: a winding station (3) with winding members (5, 7) operated by winding motors In (8.1, 8.2); an unwinder (31.1, 31.2) with an unwinding member (35.1, 35.2) operated by at least one unwinding motor (38.1, 38.2); guide roller (43.1, 43.2) along a feed path (P) of the web material (N, N2). There is associated with the guide roller (43.1, 43.2) at least one load sensor (42.1, 42.2), adapted to detect a parameter proportional to the tension of the web material (N; N2) guided around the guide roller (43.1, 43.2). There is also provided a control unit (71) adapted to modulate a difference in speed between the winding members (5, 7) and the unwinding member (35.1, 35.2) as a function of a signal coming from the load sensor (42.1, 42.2).

A system for forming glass rolls is provided. The system includes a glass ribbon supply system configured to supply a glass ribbon, a cutting system configured to cut the glass ribbon to a first portion and a second portion, a first glass winding system configured to wind the first portion of the glass ribbon to form a first glass roll, and a second glass winding system configured to wind the second portion of the glass ribbon to form a second glass roll.

Example implementations provide a controller comprising circuitry to align a substrate; the controller comprising: circuitry to control varying the tension of an unspooled portion of the substrate between a spool bearing the substrate and a pinch roller; said circuitry comprising circuitry to control varying the pinch load exerted by the pinch roller on the unspooled portion of the substrate.

An example method comprises operating a drive unit to advance a substrate in a substrate advance direction toward a printing station. At the printing station, a first line is printed onto the substrate. A drive unit is instructed to advance the substrate in the substrate advance direction by a target amount, and a second line is printed onto the substrate. The distance between the first and second lines in a direction perpendicular to the substrate advance direction is calculated and, based on the calculated difference, a tension of the substrate is modified.

An apparatus for manufacturing a display device includes a first roller from which a film member is unwound, a second roller around which the film member is wound, a flatness maintainer that is arranged between the first roller and the second roller and keeps at least one of an upper surface and a lower surface of the film member, flat, and a sensing unit arranged on at least one of the upper surface of the film member and the lower surface of the film member and detecting droplets dropped from a head unit onto the film member.

A continuous wire drive system for a needleless electrospinning apparatus, the electrospinning apparatus including an electrospinning enclosure and within which a nanoscale or submicron scale polymer fiber web is formed onto a substrate from a liquid polymer layer coated onto a plurality of continuous electrode wires passing through the electrospinning enclosure.
