Abstract
Abstract A cellular plank is made by continuously pulling a band of cellular material from a supply of the material. As the band is pulled, adhesive is applied to its upper, lower and sidewise faces. It is then directed into a folder which also receives a strip of wrapping material from a supply. Before the wrapping material enters the folder, it is scored along lines which will register with the four corners of the cellular band. The width of the scored strip is equal to the perimeter of an orthogonal cross section of said band. Then as the band and the wrapper pass through the folder, the latter is wrapped about the former so as to be adhered to it by means of the adhesive. After the combined material leaves the folder and the adhesive has set, it is in the form of a wrapped plank which is then cut into appropriate lengths for structural use. A preferred form is that of a block. In some cases several strips are employed for wrapping the blocks but in any event the wrapper covers the top, bottom and two sides of the block leaving the end faces open. The preferred form of cellular material is of the honeycomb type, although it is contemplated that a polyurethane or other like foam material may also be employed.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
The method of producing a cellular structural product comprising feeding a flexible wrapper strip into a folder, concurrently applying adhesive to at least two respective opposite faces of a prismatic band of honeycomb cellular material while breaking down to a level unevenness in exposed end edges of honeycomb cells extending transversely across the band and bringing up and drawing off excess adhesive through cohesion thereof by moving the band between sharply peripherally ridged adhesive applicator rolls thereby to apply the adhesive evenly across substantially the entire width of the baNd to substantially all the exposed end edges of the honeycomb cells, feeding said band into the folder along with the strip to fold and transversely wrap the strip around the band in adherence thereto, and drawing the wrapped band from the folder.
Claim 2
Independent Claim
132 words
The method of producing a cellular structural product comprising feeding a flexible wrapper strip into a folder, concurrently applying adhesive to at least two respective opposite faces of a prismatic band of honeycomb cellular material while breaking down to a level unevenness in exposed end edges of honeycomb cells extending transversely across the band and bringing up and drawing off excess adhesive through cohesion thereof by moving the band between sharply peripherally ridged adhesive applicator rolls thereby to apply the adhesive evenly across substantially the entire width of the baNd to substantially all the exposed end edges of the honeycomb cells, feeding said band into the folder along with the strip to fold and transversely wrap the strip around the band in adherence thereto, and drawing the wrapped band from the folder.
Claim 3
Dependent Claim
45 words
The method according to claim 1 including the step of scoring the flexible strip before it enters the folder to produce score lines which when the strip is folded will register with the four corners of the band, and thereafter segmenting the band into blocks.
Claim 4
Dependent Claim
38 words
The method according to claim 2 including the step of scoring the flexible wrapping strip before it enters the folder to place score lines thereon which upon folding will register with the four corners of the honeycomb band.
Claim 5
Independent Claim
119 words
The method of manufacturing a structural product comprising moving a strip of flexible wrapping material through a folder, drawing and stretching a honeycomb band from a cellular honeycomb compaction having laterally extending fins with face portions, applying adhesive to the top and bottom of the band and to the face portions of the laterally extending fins, directing said honeycomb band through said folder in engagement with said flexible strip, folding the flexible strip around the honeycomb band whereby said strip as it folds around the band laterally compresses said fins in an angular relationship and becomes adhered to end edges of the honeycomb cells and the facial portions of the fins, and withdrawing the wrapped band from the folder.
Claim 6
Independent Claim
119 words
The method of manufacturing a structural product comprising moving a strip of flexible wrapping material through a folder, drawing and stretching a honeycomb band from a cellular honeycomb compaction having laterally extending fins with face portions, applying adhesive to the top and bottom of the band and to the face portions of the laterally extending fins, directing said honeycomb band through said folder in engagement with said flexible strip, folding the flexible strip around the honeycomb band whereby said strip as it folds around the band laterally compresses said fins in an angular relationship and becomes adhered to end edges of the honeycomb cells and the facial portions of the fins, and withdrawing the wrapped band from the folder.
Claim 7
Dependent Claim
161 words
Apparatus for producing a continuous plank of structural material from a compaction of cellular material and a strip of flexible wrapper material, comprising means for guiding a compaction to be pulled into a prismatic four-side band of open cells, a pair of adhesive applicator rolls for applying adhesive to two respective opposite faces of the band, means for supplying adhesive to the rolls, each of the rolls being cylindrical in form and having a plurality of relatively closely spaced and relatively sharp annular peripheral ridges along the length of the roll, said rolls constituting means for concurrently breaking down to a level unevenness of exposed end edges of said cells while applying adhesive evenly to said end edges across substantially the entire width of said opposite faces and bringing up and drawing off excess adhesive, a folder for wrapping said strip around said band in adherence thereto to form wrapped plank, and means for drawing the wrapped plank from the folder.
Claim 8
Dependent Claim
161 words

Claim 9
Dependent Claim
56 words
Apparatus as set forth in claim 5, including adhesive applicator means for applying adhesive to the two remaining opposite faces of the band, and means for scoring the wrapper strip to provide a plurality of score lines which will register with the four corners of said band when the wrapper strip is folded around the strip.
