Abstract
A bristle cleaner station for a conveyorized sheet material cutting machine includes a plurality of air jets that direct pressurized air between downwardly extending bristles of a bristle bed to dislodge debris; and a vacuum chamber adjacent to the bristles to draw away the dislodged debris. The preferred embodiment uses air needles that extend into downward extending bristles to riffle or bend the bristles, making an enlarged space between them. The air needles direct pressurized air into the enlarged space to dislodge debris, and an upwardly open vacuum channel adjacent to the air needles and bristles collects the dislodged debris. A method to clean bristle beds is also disclosed whereby pressurized air is directed between the bristles and vacuum draws away dislodged debris.
