FIELD: woodworking industry, particularly for measuring moving timber thickness. ^ SUBSTANCE: device comprises conveyer for feeding timber material to be adjusted to obtain predetermined timber thickness, thickness measuring means, processing unit to determine insufficient timber thickness, means to distinguish above timber from another ones. Thickness measuring means determines timber thickness in several points during conveyance thereof on the base of main output signals generated by displacement transducers. Displacement transducers are located in several locations along timber width. If timber has several parts of a given length with thicknesses deviated from tolerance band for predetermined value in conveyance direction one can come to conclusion that timber has insufficient thickness. ^ EFFECT: reduce time of thickness determination, increased quality thereof. ^ 5 cl, 8 dwg |
