The length of the band knife may differ (e.g. 2825, 3500, 3795, 3800, 3860, 4000, 4435, or
●
4920 mm). The longer it is, the larger and more powerful the cutting machine will be.
The width of the band knife may be 10, 12, 15, 20, or 35 mm. The knives of 10, 15, and
●
20 mm are the most widely used. As a narrower knife has a smaller cutting surface, it has a
greater degree of precision, although the steel band will become blunt more quickly.
The thickness of the knife does not differ as widely (0.45 or 0.50 mm). The standard thick-
●
ness is 0.45 mm.
Band knives with two smooth blades (double-bevel knives) are used to cut textiles
(see Fig. 8.12).
