Method and device for cutting by means of a number of saw blades placed axially in a line next to each other and suspended to pivot in a cutting station connected to a trimming mill for trimming pieces of timber, whereby one or more cross-cutting saws designed for cutting are lowered for cutting via a guidance and control device. The relevant cross-cutting saw (11) is made to rotate for cutting in such a direction that its lower periphery, the one facing the conveyor (10) and piece of timber (17), moves opposite to the direction of motion of the piece of timber, that a down-deflecting means (36), suspended from the relevant arm (23), is brought into contact with the upper surface of the piece of timber that is fed forwards by the conveyor when the cross-cutting saw is lowered by its lower edge, and upstream of the cross-cutting saw (11) when seen in the direction of transport, whereby the piece of timber that is to be cut is pushed under the down-deflecting means by the driver pins (13), when the piece of timber is touched by the cross-cutting saw. |
