MESSEINRICHTUNG FUER LANGGESTRECKTE GEGENSTAENDE, INSBESONDERE HOLZSTAEMME

摘要

The diameter of elongate objects 4, e.g. logs 7, on a moving conveyor 25 is measured by transverse emitter 11 and receiver 12 arrays. The cross-section of the conveyor guideway 27, on which the objects 4 are transported by carriers 34, is reduced 37 to accommodate some of the measuring beams. Alternatively, the guideway may be offset (fig. 5) or a complete guideway gap may be provided (fig. 10), bridged by a shuttling part 81. <IMAGE>
