The sound-absorbing element is fixed to the inner surface of the sound-insulating fence and is made in the form of a smooth and perforated surface between which a multi-layered sound-absorbing structure is placed. To implement the claimed method, a soundproof enclosure is used.EFFECT: increased efficiency of sound suppression.2 cl, 2 dwg

Cutter // 2616404
FIELD: woodworking industry.SUBSTANCE: invention relates to the wood-processing industry, in particular to tools for wood machining. The cutter comprises a housing and tool holders with cutter bits mounted with the use of fasteners. The housing is made composite from a base and a movable tool holder, connected by a cylindrical base in which damping elements in the form of steel springs are mounted. The base is limited in its axial displacement with the disc.EFFECT: due to the invention the wear resistance of cutter bits is increased.2 dwg

Longitudinal milling woodprocessing machine // 2616395
FIELD: wood industry.SUBSTANCE: machine comprises a transverse support with two guides arranged between the two workpieces, and a carriage adapted for longitudinal movement. The milling head, driven by an internal combustion engine, is mounted on the carriage base. At the ends of the shaft of the milling head, extending from the base of the carriage, milling cutters are arranged. One cutter has a groove profile, the other - the profile of the corresponding ridge. On jacks, arranged on the transverse supports on both sides of the guide, based elements are mounted. Two basing elements are prism-shaped and have a common axis of symmetry with a milling cutter for cutting the groove. Two other elements have basing cutter to form cutting groove and located on the same axis as the cutter, which serves for cutting ofridge.EFFECT: simplified design of the machine.2 dwg

Single-head drilling machine // 2615369
FIELD: wood-working industry.SUBSTANCE: invention relates to wood-working industry, in particular, to drilling machines. Machine comprises supporting structure, working surface, working head with multiple spindles, spindle drive means, supporting means for working head, means of controlling rotation of supporting means, means of moving working head and multiple clamps to lock workpiece. Spindle drive means comprises a motor, arranged in centre on rear side of working head. Means of supporting working head comprises a plate, on which there is a carriage, which supports said motor and working head. Means of rotating supporting means comprise a linear electric drive, connected on one side to structure, and on other side with supporting means. Drive means of working head comprises a linear electric drive, connected on one side with means of supporting working head, and on other side with carriage.EFFECT: machine comprises programmable electronic unit which controls said motor, linear electric drives and electric clamps.5 cl, 9 dwg

Bandsaw machine // 2615000
FIELD: woodworking industry.SUBSTANCE: bandsaw machine comprises a base frame with aerostatic bearings, a band saw, a saw drive in the form of a linear electric motor consisting of the rotor and the stator in the form of an arc inductor covering a portion of the drive pulley with the bandsaw. The drive pulley is the rotor of the linear electric motor. The drive pulley is made as a hollow cylinder of conductive material. The drive pulley is coaxially mounted with a clearance on a fixed support in the form of a solid cylinder of a dielectric material. The surface of the fixed support acts as a circular aerostatic support.EFFECT: increased efficiency factor of the drive.1 dwg
