strips 17 into the grooves, and securing the strips within the
grooves by rolling the material adjacent the sides of the grooves

metal section as used, for example, in the construction industry,
in window construction, in the construction of vehicles or
machines or similar application areas” (page 1). The
specification also indicates that one of the particular problems
with which the appellant was involved was “to provide a cost-
