<p>A cleaner (50, 84, 102, 102a) for cleaning debris from the bristles of a bristle bed which provides the work material support surface for a sheet material cutting machine performs its cleaning operation while the bristle bed or the bristle units making up the bristle bed remain in place on the cutting machine. A plurality of blades (56, 56a, 56b) which may be either rotary or non-rotary are fixed to and spaced relative to one another along a given line (58). During a cleaning operation the blades enter the bristle bed and are moved in a direction perpendicular to the given line (58) and parallel to the support surface to dislodge debris from the bristles. A vacuum device (68) may be included in the cleaner to collect the dislodged debris and the cleaner may also include a vibrator (72, 96) for vibrating either the blades or the bed in the vicinity of the blades to assist in freeing the debris from the bristles. <IMAGE></p> |
