Abstract

An exhaust duct is arranged vertically slidably on a vertical board saw so that it always follows the vertical movement of the sawing unit during horizontal cutting. The exhaust duct is formed by a U-shaped profile, in which an endless driven band is guided. A slot provided in the band is located in front of the saw blade (S) in every position of the sawing unit; the sawdust thrown off by the saw blade thus passes through the slot into the space enclosed by the band and is exhausted. A sealing element is fitted on the front band side just in front of the slot. The apparatus ensures a virtually 100% discharge of the chips and sawdust in the case of horizontal cutting, which is of great significance particularly in sale rooms and exhibition rooms, and contributes to humane conditions in the workshop.
