Method and installation for cutting squared timber into boards of a predetermined thickness
First Claim
1. Method for cutting squared timber (26) into a plurality of thin boards (32) comprising the steps of:
- providing at least one blade for cutting a thin board from squared timber;
providing a squared timber (26) having a thickness with respect to a direction vertical to a cutting plane of the blade (30), said thickness being larger than a sum of thicknesses of a selected number of individual boards (32) to be cut from the squared timber;
cutting the squared timber into said selected number of individual boards (32) in succession with said blade (30), each of said individual boards having a predetermined thickness, said blade cutting essentially in a longitudinal direction of the squared timber (26); and
reducing a residual board remaining after the cutting of the selected number of individual boards to a predetermined thickness by shaving.

Abstract
The present invention concerns a method for cutting squared timber into a number of thin boards. Individual boards 32 are cut off by a blade 30 from the squared timber in each of the successive cutting machines 14a-g, essentially in longitudinal direction of the squared timber. The thickness of the squared timber 26 is selected in such a way that, once an integral number of boards having a predetermined thickness are cut off, a residual board remains which is reduced to the same thickness d as the boards 32 by shaving. The shaving preferably takes place by placing a planer 18 after the last cutting machine 14g. The installation 10 is equipped with a material feed 12 and a conveying system 20 for removing the cut boards, the cutting machines and the planer are also connected to one another by conveying devices 16, 24.

3. Installation for cutting a squared timber (26) into a plurality of thin boards (32), each board having a predetermined thickness, said installation comprising:
-
a series of cutting devices (14a-g), arranged in succession, each of said cutting devices for clean cutting one board (32) of a predetermined thickness from one side of the squared timber (26); and a shaving device (18) disposed downstream of the series of cutting devices (14a-g) with respect to a direction of travel of the squared timber through the cutting devices, said shaving device for reducing the thickness of a residual board of the squared timber (26) coming from the series of cutting devices (14a-g). - View Dependent Claims (4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16)
