Abstract
A transformer unit for sawing, wherein the transformer unit comprises: a first machine element for performing a continuous rotational motion, and a second machine element for performing a limited alternating rotational motion, wherein the transformer unit can be coupled to an arrangement supplying driving energy for the transformer unit, wherein the first and the second machine elements are coupled to a chain saw with a guide bar, wherein the first machine element is for rotating the chain saw, wherein the second machine element is for feeding the guide bar and for returning the guide bar to the starting point of the sawing after the sawing. The second machine element is a wing torsion device operated by pressurized medium, comprising an annular space for the pressurized medium.
