DEVICE FOR WORKING WOOD FOR SAWN TIMBER Russian patent published in 1994 - IPC

FIELD: wood working. SUBSTANCE: centering unit of the device has centers 8 mounted for rotation in vertical planes onto posts 9, support members are mounted under centers 8. Support members are made in form of rotary levers 14 provided with rollers 15. Device loading mechanism 4 is made in form of clamping units 19, 20 made of beams which may rotate restricted. Controllable head provided with rotary clamping levers is mounted onto any beam. Axes of rotation of clamping levers are parallel to axes of rotation of the beams. Vertical plane crossing the beams is perpendicular to vertical planes of rotation which cross axes of rotation of support members. Axes of rotation of support members are perpendicular to direction of movement of center posts. Working surface of the conveyer is disposed above axes of rotation of the beams. Conditions of clamping and orienting of round wood are improved when the device operates. EFFECT: widened operational capabilities; improved quality of production; reduced dimensions of the device. 6 cl, 3 dwg
