Abstract

A log handling device, having a rotatable rotor provided with a log handler, and a feeder attached to the rotor for conducting an operating medium to the log handler. The feeder is arranged to wind around the rotor when the rotor is rotated in a first direction, and which feeder is arranged to unwind from around the rotor when the rotor is rotated in a second direction. The log handling device includes a rotatable second rotor to which the feeder is attached, and an operating device for rotating the second rotor synchronously with the rotor, such that the feeder is arranged to wind around the second rotor when the rotor is rotated in the second direction, and such that the feeder is arranged to unwind from around the second rotor when the rotor is rotated in the first direction.

Dependent claims

A log handling device, comprising:

a rotatable rotor provided with log handling means, and
a feeding means attached to the rotor for conducting an operating medium to the log handling means,
the feeding means being arranged to wind around the rotor when the rotor is rotated in a first direction,
the feeding means being arranged to unwind from around the rotor when the rotor is rotated in a second direction,
a rotatable second rotor to which the feeding means is attached, and
an operating device for rotating the second rotor synchronously with the rotor, such that the feeding means is arranged to wind around the second rotor when the rotor is rotated in the second direction, and wherein the feeding means is arranged to unwind from around the second rotor when the rotor is rotated in the first direction;
wherein the second rotor comprises a rim to which the feeding means is attached and around which the feeding means is arranged to wind,
wherein the second rotor comprises a second rim, the diameter of which is smaller than the diameter of the rim and which is arranged to rotate concentrically with the rim, and
wherein the feeding means is passed from the rim to the second rim and is attached to the second rim.
