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.
Claims19
A rotary cutter for a rotary cutting apparatus comprising:
- a hollow rotary mantle having at least one cutting member on a cylindrical outer periphery thereof, and through-holes extending generally radially through the mantle;
- and
- an air distribution mechanism comprising:
- a first air distribution part affixed to the mantle coaxially therein for rotation therewith, and
- a second air distribution part arranged inside said first air distribution part, wherein the first distribution part is rotatable relative to the second distribution part,
- wherein 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.
A rotary cutting apparatus comprising:
- a rotary anvil;
- and
- a rotary cutter disposed opposite the anvil and including a hollow rotary mantle having at least one cutting member on a cylindrical outer periphery thereof, through-holes extending generally radially through the mantle;
- and an air distribution mechanism comprising:
- a first air distribution part affixed to the mantle coaxially therein for rotation therewith, and
- a second air distribution part arranged inside said first air distribution part, wherein the first distribution part is rotatable relative to the second distribution part,
- wherein 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.
