A printing apparatus includes: a printing unit configured to perform printing on a sheet; a driving unit configured to apply a rotational force to a roll member that is rotatably held; and a pressing unit having a roller configured to apply a pressing force to an outer peripheral surface of a roll sheet wound around the roll member, wherein the pressing unit changes the pressing force during a sequence in which the driving unit applies a rotational force to the roll member and a sheet that has passed through the printing unit is wound.

A slitter device includes a first tension detecting unit for obtaining a raw-cloth tension value which is a tension value of a sheet material fed out from a let-off mechanism, a second tension detecting unit for obtaining a divided material tension value which is the sum of the tension values of each of divided sheet materials, and a drive control device which includes a comparator to which the first tension detecting unit and the second tension detecting unit are connected, and which compares the raw-cloth tension value and the divided material tension value with each other; and a drive controller which controls an operating state of a roll driving motor such that the raw-cloth tension value and the divided material tension value coincide or substantially coincide with each other based on the comparison result of the comparator.

In a front/back reversing unit, a base metal sheet having rollers attached thereon is engaged with a rotation spindle fixed to a fitting such that the base metal sheet is rotatable in a horizontal direction. When an operation of rolling up a print target medium is started and if winding tension with respect to the print target medium to be wrapped around a winding shaft becomes unbalanced, the front/back reversing unit rotates in accordance with the winding tension so as to balance the winding tension. Then, when the winding tension applied to the print target medium becomes balanced, the front/back reversing unit is returned to its original position by an elastic member, and the roller of the front/back reversing unit and the winding shaft become substantially parallel to each other.

A method is disclosed for transferring a film, preferably a wound-on stretch film, wound onto a winding mandrel, oriented in particular vertically and preferably supported exclusively in the region of its upper end, of an unwrapping apparatus, such that when the transfer position of the winding mandrel is reached, the film wound onto the winding mandrel is pulled off the winding mandrel by means of at least one transfer device and delivered to a disposal area. An apparatus for transferring a film, preferably a wound-on stretch film, wound onto a winding mandrel, oriented in particular vertically and preferably supported exclusively in the region of its upper end, of an unwrapping apparatus, is disclosed. The apparatus encompasses at least one transfer device for pulling off the film wound onto the winding mandrel when the transfer position of the winding mandrel is reached.

A method includes applying a coupling agent solution to a major surface of a continuously moving glass ribbon to form a coupling agent coated region of the glass ribbon. The glass ribbon is a flexible glass ribbon having a thickness of at most about 300 m. The method includes heating the coupling agent coated region of the glass ribbon to form a coupling agent treated region of the glass ribbon and winding the glass ribbon onto a collection roll. A glass ribbon has a thickness of at most about 300 m and a major surface. At least a portion of the major surface includes a coupling agent treated region. Upon forming a polymeric layer on the coupling agent treated region at least five months after forming the coupling agent treated region, the polymeric layer has a peel force of at least 200 gf/in.

A method for winding a foil onto a winding core in order to form a coil and for unwinding the foil from the winding core. The foil comprises a support material of an electrode foil and an electrode foil, which has at least one active material, or a separator foil which are used as components of a battery cell. The winding core has a perforated circumferential surface with at least one opening. A coil is also provided that has at least a winding core and a foil which is wound on the winding core.

In some implementations, a reeling device may receive material via a receiving end of a set of guiding blocks positioned around a reel. The set of guiding blocks are configured with an opening at the receiving end and with one or more inner surfaces configured to guide the material on a path around a surface of the reel. The one or more inner surfaces of the set of guiding blocks are arc-shaped to generally follow the surface of the reel. The reeling device may operate a motor that rotates the reel in a loading direction to facilitate loading the material onto the reel. The set of guiding blocks travel generally away from the surface of the reel based on the material being received and/or the motor operating in the loading direction.

An apparatus and a process is disclosed for applying a boron coating to a thin foil. Preferably, the process is a continuous, in-line process for applying a coating to a thin foil comprising wrapping the foil around a rotating and translating mandrel, cleaning the foil with glow discharge in an etching chamber as the mandrel with the foil moves through the chamber, sputtering the foil with boron carbide in a sputtering chamber as the mandrel moves through the sputtering chamber, and unwinding the foil off the mandrel after it has been coated. The apparatus for applying a coating to a thin foil comprises an elongated mandrel. Foil preferably passes from a reel to the mandrel by passing through a seal near the initial portion of an etching chamber. The mandrel has a translation drive system for moving the mandrel forward and a rotational drive system for rotating mandrel as it moves forward. The etching chamber utilizes glow discharge on a surface of the foil as the mandrel moves through said etching chamber. A sputtering chamber, downstream of the etching chamber, applies a thin layer comprising boron onto the surface of the foil as said mandrel moves through said sputtering chamber. Preferably, the coated foil passes from the mandrel to a second reel by passing through a seal near the terminal portion of the sputtering chamber.

An apparatus for transportation of a thin film substrate under vacuum conditions is described. The apparatus for transportation includes a rotatable roller with a substrate facing surface including a first substrate facing surface portion, wherein the substrate facing surface includes one or more gas outlets, wherein the one or more gas outlets are configured for releasing a gas flow and the roller includes a deposition region and at least one non-deposition region. The apparatus further includes a gas distribution for providing the gas flow through the one or more gas outlets into an interspace between the thin film substrate and the first substrate facing surface portion, and a sealing belt conveyor system including one or more sealing belts provided at the at least one non-deposition region.

The present disclosure provides a conveying roller cleaning method, a conveying roller cleaning device, and a material tape conveying equipment. In the conveying roller cleaning method, the conveying roller is configured to convey a material tape, and the cleaning method includes: connecting a head end of an adhesive tape with a tail end of the material tape; and the material tape pulling the adhesive tape to move so as to make the adhesive tape pass through the conveying roller and remove impurities from a surface of the conveying roller. The conveying roller cleaning method can clean the conveying roller.
