Device in an apparatus for processing trees

An apparatus for processing trees comprising a grabbing device including at least two grabbing arms being movable towards and away from each other in order to grab a tree, at least one limbing member to limb the tree, and at least two rolls to feed the tree through the apparatus, said rolls being arranged on said grabbing arms in order to follow the grabbing arms in their movements towards and away from a tree movement path through the apparatus, said apparatus being connected to a crane arm through a first rotational connection allowing pivotal movement of the apparatus relative to the crane arm in an essentially vertical plane, the apparatus being connected to the crane arm through a second rotational connection having an essentially vertical axis about which the apparatus is rotatable in a suspended state by means of a drive means with said grabbing arms depending downwardly from said second rotational connection, a second limbing member being connected to a part interconnecting the grabbing arms, said second limbing member being movable in an essentially straight path, and a spring for counter-acting movements of the second limbing member away from the center of the tree movement path through the apparatus.

An apparatus for processing trees comprising at least two arms, means mounting said arms for movement toward and away from each other, and at least one limbing member to limb the tree, each of said arms carrying at least one roll, said rolls being adapted to feed the tree trunk through the apparatus, and said rolls being pivotable relative to the arms about shafts extending essentially perpendicularly to the axes of rotation of said rolls and essentially normal to the plane of movement of the arms.

An apparatus for processing trees comprising at least two arms, means mounting said arms for movement toward and away from each other, and at least one limbing member to limb the tree, each of said arms carrying at least one roll, said rolls being adapted to feed the tree trunk through the apparatus, said limbing member being connected to a part interconnecting the arms, and said limbing member being movable along a guide in an essentially straight path and associated to at least one spring counteracting movements of the limbing member away from the center of the tree movement path through the apparatus.
