the fiber feeding device (fluted feed cylinder C and spreading
device F) and situated between the fiber feeding device and
the licker-in (breaker roll B). The breaker roll A rotates at
a lower velocity than the breaker roll B so as to open and
clean the fiber material in a gradually accelerating manner
which is said to improve the performance and efficiency of the
carding process (see, for example, pages 1, 2, 4 and 7).
Weber teaches that the licker-in or breaker roll B has a
