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 rewinding machine for the production of rolls of web material wound around winding cores includes: a winding cradle including peripheral winding members of the rolls; a feeding path of the web material towards the winding cradle; an insertion channel for inserting the winding cores towards the winding cradle, having an entrance inside which the winding cores are introduced and an exit toward the winding cradle, the insertion channel being defined between a rolling surface and a continuous flexible member, provided with a forward movement; an inserter for inserting the winding cores into the inserting channel. At the entrance of the insertion channel a pressing device is arranged, said pressing device projects toward the inside of the insertion channel and toward the continuous flexible member. The pressing device is arranged and configured to press the winding cores entering the insertion channel towards the continuous flexible member.

A surface winder for winding a web material around a core to obtain a log is disclosed. The surface winder provides a core inserter for inserting a core into an introductory portion of a winding cradle defined by an upper winding roller, a concave cradle, a lower winding roller, and a third oscillating roller. The concave cradle has a leading edge device having a surface with at least one channel disposed therein. The at least one channel has a single entry point and a single exit point and extending from a position external to the leading edge device and a first location disposed upon the surface capable of receiving a fluid from the at least one channel. The fluid is fluidically displaced onto the core from the at least one channel when the core is in contacting engagement with the first location disposed upon the surface.

The invention relates to a receiving means (200) for receiving film material (250) for use in a winding machine (IO), wherein the receiving means (200) comprises at least one bearing region (210) for attaching the receiving means (200) to a winding unit (20) of the winding machine (IO) and comprises a wall (220) having an outer surface region (230), wherein the wall (220) is designed in such a way that the surface region (230) can be placed onto a transport device (30) of the winding machine (10) and the film material (250) can be received onto the surface region (230).

An improved paper band delivery assembly for reliable high speed delivery of a turn-up paper band across a moving web of paper being wound onto a spool. The turn-up paper band is made ready for a turn up procedure by coiling a predetermined length of paper band suitable for a particular machine and retaining the coiled paper band in a reservoir pending deployment across a spool for a turn up procedure. The paper band may be coiled via manual operation or via automated operation. Coiling apparatus may be modularly replaced on a paper making machine. The coiled paper band may be supported within the reservoir on rollers, pins, or other items conducive to fast and reliable uncoiling.

A manufacturing method for a glass roll includes cutting a glass ribbon along a longitudinal direction thereof in a cutting region on a conveyance path while conveying the glass ribbon, and taking up the cut glass ribbon around a roll core at a downstream end of the conveyance path. A conveyance-mode changeable region is provided between the cutting region and the downstream end of the conveyance path. The conveyance-mode changeable region enables a change in conveyance mode between a first mode of conveying the glass ribbon in a tensioned state and a second mode of conveying the glass ribbon in a loosened state. After the leading end portion of the glass ribbon is wound around the roll core in the first conveyance mode, the conveyance mode is shifted from the first conveyance mode to the second conveyance mode.

An apparatus for dispensing an adhesive with paper covers to be used in a paper web turn-up operation. The resulting adhesive and paper cover construct is used in effecting the attachment of a paper web to an approaching spool. In some examples, the paper cover of the deposited adhesive may be affixed on two sides surrounding the deposited adhesive, in other examples a single attachment may be used. In some examples, the paper cover may be perforated to facilitate rupture of the paper and flow of adhesive. In some examples, perforations may enable the movement of adhesive through the paper.

A coiling device includes a coiler (1) having a coiling mandrel (3) for coiling a metal strip (2) which is fed (x) to the coiler (1), and a coiling swing arm (4) having a front and a rear pressure roller (5, 6) and a deflection plate (7). A swing arm drive (8) lines up the coiling swing arm (4) with the coiling mandrel (3) and is driven away from the coiling mandrel (3). An upper duct flap (9) upstream of the coiler (1) in the feed direction (x) for guiding the metal strip (2). A flap drive (10) for positioning the upper duct flap (9) such that, when the coiling swing arm (4) is lined up with the coiling mandrel (3), the upper duct flap is arranged between the coiling mandrel (3) and the front pressure roller (5) of the coiling swing arm (4) or is arranged upstream of the front pressure roller (5) of the coiling swing arm (4). In the first-mentioned case, the metal strip (2) is deflected around the coiling mandrel (3) only by the rear pressure roller (6) and the deflection plate (7) of the coiling swing arm (4) and, in the last-mentioned case, additionally also by the front pressure roller (5).

A sheet-feeding system includes a holding part which holds an end portion of a sheet, a nozzle part for discharging an adhesive agent for joining sheets to each other, and a nozzle moving unit which supports the nozzle part such that the nozzle part is made movable within a region including both temporarily holding parts, in which when a sheet joining condition is established where a remaining amount of the sheet on one original sheet roll becomes equal to or below a predetermined remaining amount, an end portion of the sheet on the other original sheet roll is conveyed to the temporarily holding part by the holding part and, thereafter, the nozzle part is moved to the temporarily holding part, and the adhesive agent is discharged to the end portion of the sheet from the nozzle part.
