The apparatus can ensure that seams between panels in one layer are laterally displaced from seams in adjacent layers and can provide for wrapping paper or cardboard around the corrugated web. ## Claims ### Claim 1 An apparatus for the manufacture of a laminated web from recycled corrugated cardboard comprising: (a) means for sorting panels of corrugated cardboard; (b) means for laying a first layer of said panels of corrugated cardboard in edge to edge relation; (c) means for laying a second layer of said panels in edge to edge relation with each other and in face to face relation with said panels of said first layer, at least one of said means for laying said layers being adapted to lay said panels in edge to edge relation in both the direction parallel to the length of the said web and the direction perpendicular to the length of said web; and (d) means for adhering said first layer to said second layer. ### Claim 2 An apparatus for the manufacture of a laminated web from recycled corrugated cardboard comprising: means for laying a first layer of panels of corrugated cardboard in edge to edge relation and means for laying a second layer of said panels in edge to edge relation with each other and in face to face relation with said panels of said first layer, at least one of said means for laying said layers being adapted to lay said panels in edge to edge relation in both the direction parallel to the length of the said web and the direction perpendicular to the length of said web; means for adhering said first layer to said second layer; and at least one sensor for detecting edge to edge joints between said panels in a first layer and means for preventing edge to edge joints of said panels in a second layer from being laid within a predetermined distance of the edge to edge joints of said first layer. ### Claim 3 (depends on 2) The invention of claim 2 further comprising means for pre-processing recycled cardboard into said panels. ### Claim 4 (depends on 3) The invention of claim 3 wherein said means for pre-processing comprises means for removing irregularities from said cardboard. ### Claim 5 (depends on 3) The invention of claim 3 wherein said means for pre-processing comprises means for cutting said cardboard into panels of at least one standard width. ### Claim 6 (depends on 2) The invention of claim 2 wherein said means for adhering said first layer to said second layer comprises at least one glue applicator. ### Claim 7 (depends on 2) The invention of claim 2 wherein said means for preventing edge to edge joints of said panels in a second layer from being laid within a predetermined distance of the edge to edge joints of said first layer comprises a shear for trimming said panels. ### Claim 8 (depends on 2) The invention of claim 2 wherein said means for preventing edge to edge joints of said panels in a second layer from being laid within a predetermined distance of the edge to edge joints of said first layer comprises means for selecting alternate panels of different lengths. ### Claim 9 An assembly line for the manufacture of a laminated web from recycled corrugated cardboard comprising: (a) means for cutting cardboard materials into usable panels; (b) means for removing irregularities from said panels (c) means for sorting said panels; (d) at least one bin for storing panels of a least one standard width and sorted by thickness; (e) at least one panel dispensing means for laying said panels into end to end relationship; (f) at least one first sensor means for identifying joints on a layer of said panels; (g) at least one second sensor means for determining the length of said panels within said bin means; (h) means for ensuring that the ends of each said panel dispensed by said panel dispensing means does not fall within a pre-determined distance of a joint in a preceding layer of panels; (I) adhesive dispensing means; and (j) compression means. ### Claim 10 (depends on 9) The invention of claim 9 wherein said bin is movably mounted to dispense panels over a pre-determined area and wherein said means for ensuring the placement of said panel ends comprises panel return means for re-routing said panels from said panel dispensing means to said bin if said panel would fall within a pre-determined distance of a joint in a preceding layer of panels. ### Claim 11 (depends on 9) The invention of claim 9 wherein said bin is stationary so as to dispense panels end to end on a moving conveyor and wherein said means for ensuring the placement of said panel ends comprises panel return means for re-routing said panels from said panel dispensing means to said bin if said panel would fall within a pre-determined distance of a joint in a preceding layer of panels. ### Claim 12 (depends on 9) The invention of claim 9 wherein said bin is movably mounted to dispense panels over a pre-determined area and wherein said means for ensuring that said panel ends do not fall within a pre-determined distance of a joint in a preceding layer of panels comprises a shear for trimming said panel until the ends of said panel do not fall within a pre-determined distance of a joint in a preceding layer of panels. ### Claim 13 (depends on 9) The invention of claim 9 wherein said bin is stationary so as to dispense panels end to end on a moving conveyor and wherein said means for ensuring that said panel ends do not fall within a pre-determined distance of a joint in a preceding layer of panels comprises a shear for trimming said panel until the ends of said panel do not fall within a pre-determined distance of a joint in a preceding layer of panels.
