FIELD: process engineering.

SUBSTANCE: invention relates to woodworking industry. Claimed machine comprises the bed, trough-shape table with angular opening and saw shaft with its support fitted in the opening, four-roll feeder, prop with axle and guide blade, actuators fitted at the edger bed, upper guard with upper rolls lifting mechanism and two rows of grapple curtain.

The strap with the insert fitted therein and secured thereto by two screws level with the table and provided with brackets arranged at its ends is arranged at the housing upper surface perpendicular to the saw shaft. The brackets rest on the table ledges arranged at the opening edges parallel with the saw shaft to accommodate two round-section links with their ends connected with strap brackets. The guide blade is arranged at the link located behind the saw shaft in the feed direction and aligned with the saw. The blade is secured by the screw to the strap. The guide is arranged at the upper guard front wall of the bracket to support the stationary laser and moving laser fitted at the slide aligned with the saw.
