MATERIAL FEEDER Russian patent published in 2016 - IPC B65H1/30 

FIELD: process engineering.

SUBSTANCE: claimed device comprises the lower guide with sheet materials laid thereon inclined so that its feed guide side feeding the sheets at the lowest section of the pile is located lower. Device rollers, each with the main section, of, mainly, cylindrical shape and with the separation section located at the main section peripheral side surface, apply the friction forces to the material. Note here that said rollers spin so that said separation sections extend toward the laid materials from the bottom side of separation openings in the lower guide. Besides, it comprises the overlapping guide to support the piled materials on the lower guide feed side. The pressure element of preset weight exploits the gravity force to press the piled material to said lower guide. The extra pressure element is fitted between the pressure element and piled materials. The absorbing elements are meant for damping the force applied by materials to said extra pressure element.

EFFECT: ordered feed without disintegration of piles.
