MULTILAYER BATTERY SEPARATORS
A microporous battery separator is provided having a first co-extruded multilayered portion and a second co-extruded multilayered portion. The two portions are bonded together. In a preferred embodiment, the battery separator has two substantially identical multilayered portions bonded together face-to-face. Each of the two multilayered portions has at least one strength layer and at least one shutdown layer. Methods for making the battery separators are also provided. Preferably, a tubular multilayered film is extruded, and collapsed onto itself to form a multilayered battery separator precursor. The precursor is then bonded and annealed before it is stretched to form a microporous multilayer battery separator.

Fitting device and fitting method for cylindrical film body
A label fitting device cylindrically opens and feeds downward an individual label, and thereby fits the individual film body around a fitting target carried to a fitting position. The label fitting device includes a feed unit which feeds downward the label base material while changing the carrying direction thereof, and a label fitting unit which carries downward the label and fits the label to the container. The label is formed by cutting the label base material fed by the feed unit. The label fitting unit is provided so as to be turnable relative to the container to thereby enable adjustment of the fitting angular position of the cylindrical label relative to the circumferential direction of the container.

Cloth attachment device and cloth attachment method using the same
A cloth attachment device includes a frame, and further includes: a first roller arranged on the frame and capable of being rotated around its axis relative to the frame; a transmission mechanism arranged on the frame and capable of being moved relative to the frame, a to-be-attached cloth being arranged between the first roller and the transmission mechanism, two opposite surfaces of the to-be-attached cloth being in contact with a first position on the transmission mechanism and a second position on the first roller, respectively; and a driving mechanism configured to drive the first roller to rotate and drive the transmission mechanism to move in such a manner that the first position and the second position are moved in an identical direction, thereby to enable, through the transmission mechanism, the to-be-attached cloth between the first roller and the transmission mechanism to be curled up around the first roller.
Fiber-reinforced film processes and films
Cast-film process for making a fiber-reinforced film is disclosed. The process includes providing at least a first thermoplastic resin, melting the at least first thermoplastic resin, extruding the at least first thermoplastic resin through a first extension die to form a first thermoplastic film, providing at least a second thermoplastic resin, melting the at least second thermoplastic resin, extruding the at least second thermoplastic resin through a second extension die to form a second thermoplastic film, transporting the first and second thermoplastic films along respective casting rollers, and introducing a plurality of fibers between the first and second thermoplastic films so as to form a fiber-reinforced film having a thickness between about 0.2 mil to about 2.0 mils and having a first thermoplastic layer, a second thermoplastic layer, and a plurality of fibers dispersed therebetween. Cast-film process for making a fiber-reinforced bag is also disclosed.
