An improved method and tooling for a pouch forming machine to attach a fastener to the bag film layers. The method and fixture in one embodiment can unwind a double wide touch and close fastening material and then split the fastener into two strips using two turning bars, invert one of the strips, bring the strips together to interlock them with a nip roller, and then insert the interlocked strip between the bag film layers.

A guide film supply mechanism feeds a guide film toward a winding mechanism. The guide film is a film in which a pair of supports, which is long in the longitudinal direction of a base film and is thicker than a product film, is disposed on both side portions of the upper surface of the base film that is formed to have a width larger than the width of the product film. A product film supply mechanism feeds the product film toward the upper surface of the guide film. The winding mechanism forms a film roll by winding the product film for each guide film. The tension of the product film is set to be smaller than the tension of the guide film.

A winding apparatus for secondary batteries includes a first clamp having a first contact portion to be in contact with a separator in a longitudinal direction, a second clamp having a second contact portion to be in contact with the separator in the longitudinal direction, the second contact portion being configured to be engaged with the first contact portion while the separator is therebetween, blades surrounding the first clamp and the second clamp, the blades being configured to allow the separator to be wound therearound, and a driver configured to move the first clamp and the second clamp toward each other and away from each other.

An apparatus for the production of inner assemblies, including a feeding unit configured to feed at least one web along a feed path, a movable frame, movable between a proximal position and a distal position, the proximal position being closer to the feeding unit than the distal position, at least one winding device mounted on the movable frame and configured to wind the at least one web around a winding support to form an inner assembly, a holding member mounted on the movable frame, movable between a holding configuration, wherein the holding member is configured to hold the inner assembly wound on the winding support, and a disengagement configuration wherein the holding member is configured not to hold the inner assembly wound on the winding support, an extraction mechanism configured to extract the winding support from the inner assembly at least partially while the holding member holds the inner assembly.
