4.1 Stitching wire
The ECONOMY 25/40 processes stitching wire of standard quality
Round wire No. 21 - 30 (diameter 0.80 - 0.35 mm)
Flat wire No. I - VI (0.70 x 0.35 to 0.96 x 0.78 mm)
Thumb rule
The thicker the material to be stitched, the thicker the wire, but it should be not thicker than neces-
sary. A wire that is too thick is not aesthetically pleasing, but a wire that is too thin will result in mis-
takes!
Stitching wire - round or flat?
Very thin folders of just a few sheets are usually stitched with round wire no. 30 or 28. The selection
of round or flat wire is dictated by experience and economy (round wire is cheaper). Blocks of 18
mm thickness can be stitched with either round or flat wire. For thicknesses over 18 mm, we recom-
mend flat wire in principle.

Occasionally you might
need a stronger type of
wire, e.g. when working with
very hard paper or in case
of blunt cutters, which
weaken the driving power of
the staples.
