A method of manufacturing a battery including a wound electrode assembly in which a first separator, a negative electrode plate, a second separator, and a positive electrode plate are wound together is disclosed. The method includes step (A) of suction-attaching the first separator to a winding core, and step (B) of winding the first separator on the winding core. The winding core includes a plurality of suction holes for suction-attaching the first separator. When the outer circumference of the winding core is divided into four equal parts and the four equal parts are defined respectively as first to fourth regions starting from a position that faces a starting end of winding of the first separator, greater than or equal to 80%, by aperture area ratio, of the suction holes are formed in the first region.

A method of manufacturing a battery is disclosed. The method includes the steps of (A) suction-attaching the first separator to a winding core, (B) winding the first separator on the winding core, and (C) removing the wound electrode assembly from the winding core. The winding core includes a first group of holes and a second group of holes each formed in its outer circumferential surface. In step (A), suction is applied to the first separator through at least one of the first group of holes and the second group of holes, to suction-attach the first separator to the winding core. The first group of holes and the second group of holes are configured to be controllable so as to cause suction and gas discharge independently from each other.

A method of manufacturing method a battery includes the following steps. Step (A): causing, with the first separator and the second separator being stacked on each other, the first separator and the second separator to be suction-attached to a winding core and to be pressed against the winding core with a jig including a plurality of protrusions formed on a surface of the jig. Step (B): winding the first separator and the second separator onto the winding core.

The present disclosure relates to methods for making elastomeric laminates that may be used as components of absorbent articles. The methods and apparatuses may be configured with a plurality of elastic strands wound onto a beam, wherein one or more elastic strands comprises a spin finish. During assembly of an elastomeric laminate, the beam is rotated to unwind the elastic strands from the beam. A portion of the spin finish may be removed from the advancing elastic strand with a spin finish removal apparatus. The spin finish removal apparatus may be configured to apply detergent to an advancing elastic strand and may also wipe and/or dry the advancing elastic strand. The treated stretched elastic strand may then be connected between a first substrate and a second substrate. In some configurations, adhesive may be applied to the treated the elastic strand, the first substrate, and/or the second substrate.

A glass film transfer apparatus includes a wind-off section that winds off the glass film from a roll around which the glass film is wound, a long interleaf being laminated on the glass film; a glass film transfer section that transfers the glass film which is wound off from the wind-off section and is separated from the interleaf; a take-up section that takes up the glass film transferred by the glass film transfer section in the form of roll, while laminating the long interleaf on the glass film; and an interleaf transfer section that carries out the interleaf separated from the glass film which is wound off from the wind-off section, and carries in the interleaf toward the take-up section. Furthermore, the glass film transfer apparatus includes a take-up adjusting mechanism that adjusts a take-up state of the interleaf and the glass film in the take-up section.
