In order to manage with a lower suction capacity of the sawdust fan in the case of a vertical board saw with a sawing unit movable horizontally and vertically, a support grid receiving a workpiece, being arranged essentially vertically and displaceable in the vertical direction, this grid comprising a plurality of support bars arranged horizontally and in parallel spaced relation to one another as well as suction channels arranged at right angles hereto and opening towards the workpiece, and a device for collecting the sawdust resulting on the side of the support grid during horizontal cutting, it is suggested that the support bars be designed as essentially closed channels each with a slot-shaped opening extending essentially along the entire length of the support bar, an edge of the saw blade of the sawing unit being able to enter this opening essentially without making contact during the horizontal cutting, and that the support bar channels be connected to a sawdust collecting means, wherein the support bar channels form at the same time part of the device for collecting the sawdust resulting on the side of the support grid during the horizontal cutting.
Vertical panel saw having a horizontally and vertically displaceable saw unit, having a substantially vertically arranged and vertically movable support grid which receives a workpiece and which comprises a multiplicity of horizontally arranged support bars which are spaced from one another in parallel, and exhaust channels, which are arranged perpendicularly thereto and which open towards the workpiece, and having an apparatus for receiving the saw dust which is produced on the support grid side during horizontal cutting, such that the support bars are in the form of substantially closed channels, each having an elongate opening which extends substantially over the entire length of the support bar and into which an edge of a saw blade of the saw unit can enter in a substantially contact-free manner during horizontal cutting, and in that the support bar channels are connected to a saw dust receiving device, the support bar channel at the same time forming a portion of the apparatus for receiving the saw dust which is produced on the support grid side during horizontal cutting and, with one end, flowing into an exhaust channel, which also forms a portion of the saw dust receiving device, and the exhaust channels having a downwardly directed guide element at the entry points of the support bar channels.
Panel saw according to any one of the claims, wherein the support bar channels have, at their end connected to an exhaust channel, a guide element which guides the saw dust produced in the support bar channel into the associated exhaust channel with a component which is directed vertically downwards.
