QUADRANT FEEDING ROLLER Russian patent published in 2003 - IPC

FIELD: feeding rollers of wood-working machines, applicable in wood-working industry. SUBSTANCE: fastened on the feeding roller are sections provided with toothed quadrants that enter with their cylindrical parts the radial holes of the quadrant bodies, inserted in which are springs beforehand. The cylindrical pins entering the holes of the quadrant bodies and passing through the through slots in the cylindrical part of the toothed quadrants prevent the latters from falling out from the holes and rotate in them. Variation in thickness of simultaneously fed several bars is compensated by the shift of the toothed quadrants in the radial direction. EFFECT: simplified construction and enhanced reliability of simultaneously feed of several bars differing in height by the quadrant feeding roller. 3 dwg
