Abstract
An apparatus for the fabrication of battery separator sleeves in which two sheets of microporous plastic material are bonded to intermediately-disposed sealing strips by solvent welding or solvent adhesive bonding. Dispensers continuously apply solvent or solvent adhesive to the interfaces between continuous lengths of parallel, superposed sheet material and two, continuous lengths of sealing strips disposed between and along the lateral edges of the sheet materials. Bonding is achieved by subjecting the assembled materials to pressure applied by a series of pressure rollers and to heat applied to the lateral edges of the sheet materials by heating elements. The continuous length of formed battery separator sleeve is cut to the appropriate length.
