Abstract
In a method of producing spacer elements between pairs of mutually facing membrane surfaces for a fluid purifier, to minimize the number of separate parts required in the assembly of a membrane module for the fluid purifier, the sides of mutually parallel strings of spacer material are joined with the surfaces obliquely to a longitudinal extension of the surfaces. The surfaces are turned to face one another with respective parallel strings intersecting and abutting one another.
