Abstract:
An apparatus for cutting, segmenting, compressing and extruding waxed corrugated cardboard sheets into a firelog having radially interlocking segments, comprising:(a) a housing having an inlet end and an outlet end; (b) a plurality of lower circular blades juxtaposed along a first common axis, said plurality of lower circular blades each including a first cutting edge; (c) a plurality of upper circular blades juxtaposed along a second common axis, said plurality of upper circular blades each including a second cutting edge; and (d) a circular blade axial adjustment mechanism wherein the axial position of at least one axis of said circular blades can be positioned in relation to the other axis of circular blades to thereby provide control of the juxtaposition forces between upper and lower circular blades; (e) said plurality of upper and lower circular blades configured to slice at least one waxed corrugated cardboard sheet placed generally into the inlet end of said housing into cardboard strips; (f) wherein said first cutting edge overlaps said second cutting edge, and wherein said cutting blades are configured so that interaction between said upper cutting blades and said lower cutting blades proximal the location of cutting edge overlap causes corrugated cardboard being sliceably passed therethrough to exhibit cut edges containing significant fraying; (g) a cutting mechanism configured to cut the cardboard strips into cardboard segments; (h) a compression conveyor auger having shaft carrying a helical blade with a plurality of flights; and (i) a die, wherein said auger is configured to convey said cardboard segments into said die wherein the segments are compressed into a firelog.
