Abstract
A rotary cutter includes a hollow rotary mantle having a cutter arbor on an outer periphery thereof, through holes extending radially through the mantle, and an air distribution mechanism. The air distribution mechanism includes first and second parts. The first part is affixed to the mantle coaxially therein for rotation therewith. The second part is arranged inside the first part, wherein the first distribution part is rotatable relative to the second distribution part. The first and second air distribution parts define air passages for communicating selective ones of the through-holes of the mantle with an air source in response to relative rotation between the first and second distribution parts.
