ABSTRACT:
The disclosure describes an apparatus to move, individually and at a controlled rate, sawlogs and tree stems from a first multiple feeding station to a second station situated at a higher level than that of the first station; it comprises a frame, a set of fixed plates and a set of movable plates, both in parallel vertical planes. A system of levers is connected to the set of movable plates so as to serve as support and to supply it with a trajectory defining an arc of a circle. A rotary motor, a drive lever and a link cooperate to provide this trajectory with a sinusoidal-type acceleration.
