The system is for automatic loading of machines treating bulk material of a given length and compressed into balls. These materials are such as fibres, wire, textile waste. Some material is formed into a band moved towards the machine. - The band is given a reciprocating movement in the direction of overall band movement. The material extracted is guided and cut. A hopper is fitted on a fixed frame and has an open top. A rectangular opening is provided on the edge nearest the machine to be loaded. EPAB- EP--81886 B Method for loading automatically machines for treating bulk materials having some length and generally pressed into bales, particularly materials such as fibres, yarns, fragments from woven or unwoven textiles, plastics, comprising extracting from the bottom of a material mass, by means of projecting elements entering said mass, an amount of material to be formed into a strip which is fed to said machines, which method further comprises arranging said projecting elements in at least two rows extending along the strip movement direction, imparting to at least one element row in alternating motion along the strip movement direction to let said movable element row convey the material along the strip movement direction as said row moves along said direction, and the other element row retains the material to prevent same from moving together with the elements from said movable row as said row moves in the direction opposite to the strip movement direction and regulating the movement magnitude so as to let the material, extracted out the material mass by projecting elements, move towards and beyond an opening, the cross-section of which substantially corresponding to the section of that material strip to be formed, the projecting elements movement extending beyond this opening when these elements move along the strip movement direction. (18pp) USAB- US4516734 A Appts. for removing material from the underside of a mass of the material, e.g. a bale, for feed as an extracted web to a processing machine, comprises a hopper with an open bottom below which operate two movable bars equipped with rows of projecting spikes. - The two bars jointly close the hopper bottom, and are reciprocated out of phase in the direction of the rows of spikes. - (10pp)r
