Abstract

Procedure for the manufacture of separators for alkaline batteries, characterized in that a veil is prepared from a mixture of polyamide fibers with a high melting point and others with a low melting point., with the help of a heated steel cylinder mechanism, by thermal welding of the fibers, preferably at the crossing points thereof, the veil having a thickness between 0.1 and 0.3 mml.
