<p>The invention relates to a transformer unit, particularly for sawing, wherein the transformer unit (M) comprises a first machine element (1), particularly a shaft, performing a continuous rotational movement during the use of the transformer unit, and a second machine element (2) performing a limited alternating rotational motion on a part of the transformer unit, particularly a wing torsion device driven by pressurized medium. The transforming unit (M) is arranged to be coupled to an arrangement to supply driving energy for the transformer unit (M), such as a hydraulic pump unit. The first and second machine element (1, 2) of the transformer unit are preferably coupled to a device performing the same work. The device is used for performing first and second partial work performances, wherein in connection with a flanged chain saw it is operated in such a way that the first machine element (1) is arranged to rotate the chain saw during the sawing performance, and the second machine element (2) is arranged to feed the flange for the chain saw, or the like, during the sawing performance and to return the flange for the saw chain to the initial position of sawing during the sawing performance.</p> |
