Abstract: An apparatus for forming loose fill packing material which comprises a shredder device operative to convert sheets of corrugated cardboard into elongated, thin paper strips which are discharged onto a perforated conveyor movable between a loading position at the shredder device and a discharge position where the strips are emptied into a collection hopper. A suction device is mounted beneath the conveyor, downstream from the shredder device, which is operative to apply a suction to the cardboard strips to remove dirt, dust and other foreign materials therefrom, and then the cleaned paper strips are transmitted along an angled sifter plate having a plurality of openings which are sized to allow undesired, short strips of paper to pass therethrough for deposit into a waste hopper. A spraying device is located at the sifter plate to deposit a liquid material on the paper strips having microbicidal, sanitizing, insect repellant, disinfectant and deodorizing properties.

Abstract: This invention is directed to loose fill packing material comprising clean, elongated strips of paper formed from sheets of corrugated cardboard by an apparatus which comprises a shredder device operative to convert the sheets of corrugated cardboard into paper strips for discharge onto a perforated conveyor movable between a loading position at the shredder device and a discharge position where the paper strips are emptied into a collection hopper. A suction housing is mounted at the outlet of the shredder device in position to substantially enclose the conveyor so that a suction can be drawn over the paper strips to remove dirt, dust and other foreign materials therefrom after which the cleaned paper strips are transmitted by the conveyor to an angled sifter plate having a plurality of openings which are sized to allow undesired, short strips of paper to pass therethrough.
