<p>The log feeder has two sets of step units (2a,2b) with steps (3a,3b) to hold the logs. The step units have relative movements against each other with a crank (5) at the drive (4) to give the steps their reciprocating movements. The steps are coupled to the crank by rockers (9a,9b) and a linkage (6). The rocker axes are offset and the steps have movement at a gap from the rocker axes by a swing holding arm (7a,7b).</p> |
