<p>The panel saw has an upright supporting grid (2) with vertical and horizontal supporting bars (2a and 2b resp.). The pivotable saw unit (6) is attached to a displaceable beam (5). In order to reliably pick up the wood dust which collects behind the panel (P) to be sawed and which according to the invention amounts to 3 to 5% of the total wood dust quantity, a continuous cover element (7) is fixed to the rear side of the supporting grid (2). Moreover, a rotatably mounted spindle (A) with a sealing foil (10) which can be rolled up is arranged in the marginal area of the supporting grid (2). The sealing foil (10) is brought to bear against the panel edge adjacent to it by a counterweight arrangement (G) having tension cables (12, 18). Flow channels (K) are thereby formed between the horizontal supporting bars (2b), which flow channels (K) are defined on the rear side by the cover element (7) and on the front side by the panel (P) and the sealing foil (10). All the channels (K) open into a vertical collecting channel (8) which is connected to an extraction fan via a line (9). Owing to this arrangement, the remaining dust collecting behind the panel (P) can also be reliably extracted.</p> |
