FIG. 6 -is an enlarged sectional view taken on the line
6--6 of FIG. 2.
Proceeding iirst to a discussion of the embodiment
shown in FIGS. l, 2 and 3, there is shown a driven roll
10 and an associated chest 11. The roll in this embodi

base 12. This wire mesh could be positioned directly on
the surface of roll 10 although I show it here as attached,
for example by welding, to supporting strips 13 circum
