a certain defined height X. As is shown, the spring means 17 has a width of, for
example, a total of 2 mm, whereby the portion 17a thereof located outside the recess
9b is, for example, 0.5 mm wide.
Figure 6 of Strömberg is a schematic view of the retaining device with wedged up
knife blade with a certain, defined height. The spring means 17 is compressed when
the knife blade 2 with the height X is wedged up. As shown, the spring means 17 has
been compressed such that the portion 17a thereof located outside the recess 9b is
reduced to, for example, 0.3 mm. The spring means 17 hereby exerts a substantially
remaining spring force such that the knife blade 2 is retained in the slot 6.
Figure 7 of Strömberg is a schematic view of the retaining device with the knife
blade wedged up with a greater height. The spring means 17 has permitted a knife
blade 2 with the height X+0.2 to be wedged up in the slot 6 while maintaining the height
position of the wedge device K. Here, the spring means 17 has been compressed
more than in the embodiment described above, such that the portion 17a thereof
located outside the recess 9b is reduced to, for example, 0.1 mm.
Strömberg's spring means 17 permits mounting of knife blades 2 deviating from
a certain, defined dimension regarding their height and/or width, provided that the
