Abstract:
A paper conversion dispenser machine for converting paper sheet material into a relatively low density cushioning dunnage product, said machine comprising:a frame adapted to support a stock supplying assembly for supplying at least one stock paper roll; a shaping member for crumpling and converting paper sheet material of said roll into a three-dimensional shape, said paper sheet material having a surface and two edges, said shaping member including a pre-entry section with two side entry guiding rollers each roller being transverse to each side edge of the paper sheet material and having an axis that is perpendicular to the surface of said paper sheet material for guiding and reducing in width said paper sheet material of a supplied width to a narrower width non linear crumpled stream of paper, said stream of paper having a surface and two side edges, and an entry section with two side entry rollers, each roller of the entry section being transverse to each side edge of the stream of paper and having an axis that is perpendicular to the surface of the stream of paper for guiding and reducing in width said crumpled stream of paper down to an even narrower width relatively low density cushioning dunnage product, said entry section being spaced downstream from the pre-entry section; a guiding tunnel having a substantially uniform cross section for guiding the dunnage product received from the entry section, said guiding tunnel being positioned downstream from the entry section; a feed mechanism positioned at an exit of said guiding tunnel for driving said stock paper roll through said shaping member, said feed mechanism including first and second sets of driving and driven rollers adapted to frictionally receive said dunnage product therebetween near both edges of the dunnage product, thereby reducing in thickness said edges of said dunnage product; and a cutting set for cutting said dunnage product.
