ABSTRACT:
A log sawing and transport system for relatively small logs has an infeed and loading station where logs are positioned in a centering device for aligning the logs with respect to the saws. Once the log is properly aligned for axial movement, a set of end dogs are actuated to hold the log in its prealigned position for transport. The dogs are mounted within axially movable carriage units that travel the length of the system serving to transport the log axially in a straight line. At the sawing station a plurality of angularly arranged saws are disposed to divide the traveling log into a plurality of elongated sector-shaped pieces. At least one selected saw may be adjustable with respect to the other saws in order to set angles for the sector-shaped pieces. Once the log has been divided into a plurality of sector-shaped pieces, an outfeed device collects the elongated sector-shaped pieces and transports them out of the system.
