A core prevents a battery separator wound there a round from moving and becoming misaligned on an outer circumferential surface of the core in a widthwise direction of the core. The core allows a separator to be wound around the outer circumferential surface thereof and is made of resin. The core includes a groove formed on the outer circumferential surface thereof, the groove extending in a direction substantially equivalent to a circumferential direction of the outer circumferential surface.

A method for winding up a glass ribbon is provided, in which, prior to winding up the glass ribbon, the two surfaces of the glass ribbon are each initially treated with a water-containing medium and subsequently dried so as to produce a defined content of water molecules on the two surfaces, by achieving a saturation of the surfaces of the glass ribbon with water, without bringing about an excess of water molecules. A glass roll is produced in which the electrostatic charge of the glass surface is reduced and, as a result, any undesired excess adherence of the glass surface to an interleaf material is prevented and, in this way, glass breakage, in particular during winding up and/or unwinding of the glass roll, can be markedly reduced.

A plastic film roll includes: a convolute cardboard tube including a tubular body having a tubular body wall formed by a plurality of layers of a straight rolled cardboard sheet having a weight equal to or less than 300 gsm; a plastic film wound about the convolute cardboard tube to form a plurality of plastic film windings around the convolute cardboard tube, the plastic film windings creating a radial compression force equal to or greater than 10 bar on the tubular body wall, wherein the cardboard sheet includes a plurality of fibers, at least a majority of the fibers being substantially aligned in a tangential direction relative to the tubular body to allow the convolute cardboard tube to resist the radial compression force.

The invention relates to a method for winding up a film web, which is created in particular on a film production system, on at least one winding reel, wherein quality features of the winding reel (100) are determined. In order to determine quality features of the winding reel, at least the following steps are carried out: taking out measurements on the winding reel (100) and providing measurement values for the measurements; and filtering out at least one item of characteristic data from the measurement values.

A stretch film wrapping system for wrapping film about loads includes a wrap location for receiving loads to be wrapped; a film dispensing system including a film roll support mandrel assembly supported on a load cell that provides an output indicative of weight of the film roll support mandrel assembly and any film roll mounted thereon; and a control system for receiving the output of the load cell and configured to utilize load cell output to determine amount of film used for wrap operations.

Embodiments of the present invention relate to elongated tubular members that include at least one layer comprising a cellulose ester. In some cases, the cellulose ester may be in the form of staple fibers. The layer may be formed via a wet-laid fiber web that may also include cellulose fibers. The elongated tubular members may be suitable for use with food and/or beverage items as, for example, drinking straws or other similar items.

A dunnage conversion system includes a machine for converting a stock material into a strip of relatively lower-density dunnage, a coiling mechanism for winding the strip into a coil, a taping mechanism for automatically securing a trailing end of the strip to the coil, and a coil ejecting mechanism for automatically removing the coil from the coiling mechanism. The taping mechanism includes a guide surface between an outlet of the machine and the coiling mechanism to guide the strip to the coiling mechanism and to guide tape for engagement with a trailing end of the strip and to secure the trailing end of the strip to the coil. The coil ejecting mechanism includes a lever arm that pivots to push the completed coil off the coiling mechanism.

An Off-Road Rolling Film Vision System has a Controller Module (200), a Takeup Module (300), and a Rollout Module (400). The Controller Module (200) remotely controls a Motor (325) in the Takeup Module (300) with a Command Input (205) that has at least one Button to accept a knuckle bump for controlling a Motor (325) in the Takeup Module (300) when the Controller Module (200) is attached to a handlebar of an off-road vehicle. The Takeup Module (300) has a Motor Compartment (305), a Takeup Spool Compartment (310), a Takeup Spool Gear Compartment (315), a Takeup Film Window (320), a Motor (325), a Motor Gearbox (330), and at least one Takeup Spool Gear (340). The Takeup Module (300) may have a Takeup Spool Window (350) to provide a view of a Takeup Spool (345) within the Takeup Module (300).
