Turning device for rotating tree trunk around longitudinal axis in sawing machine - comprises lever arm linked to carrier, to end of which arm second such arm is linked.

摘要

The turning device consists of a first lever arm (8) arranged under the timber locating plane (E) of the carrier (2). One end (8a) is so linked to the carrier that it is pivotable around a first pivot axis (8b) parallel to the direction of relative movement between the carrier and the saw. A first controllable work cylinder (10) pivots the first lever arm (8) towards the carrier (2) around the first pivot axis (8b). A second lever arm at one end (9a) is so linked to the other end (8c) of the first lever arm that it is pivotable around a second pivot axis (9b) parallel to the direction of relative movement between the carrier and the saw. USE/ADVANTAGE - To turn progressively a tree trunk resting on a carrier for cutting of lengths by a band saw.
