FIELD: process engineering.
SUBSTANCE: invention relates to woodworking and may be used for processing surfaces of flat articles, say, boards, lining, parquet. Proposed device incorporates blank drive made up of rollers 1 running in bearings fitted in sidewalls 2 of device 1. Said sidewalls are tied together. Ultrasound transducer with radiator 5 is arranged perpendicular to rollers 1 and above them. Stop 8 made up of a roller to prevent transducer deflection is arranged on the side the article flows out from processing zone and in sidewalls. Lengthwise through slots are made in lateral walls to accommodate posts 10 to move there along together with flanges of radiator.
EFFECT: lower ultrasound vibrations losses, higher safety.
