ABSTRACT:
There is disclosed a method and apparatus for folding of sheet material into symmetrical and nonsymmetrical shapes. The method and apparatus is shown as applied to making a pallet construction wherein a series of symmetrical stringer members made on the apparatus of the present invention are inserted into an equal plurality of nonsymmetrically shaped cross-stringers, also made by the apparatus of the present invention, both of which have had adhesive applied while being folded to retain the shape into which they are made, a top sheet is applied and also glued in place to make a pallet. The method involves essentially supplying a sheet of material such as a fiberboard blank of appropriate composition and size, running the blank through crushing and scoring rollers to produce fold lines in the blank, and asymmetrically (making more folds from one side of the blank than from the other side) or symmetrically folding the blank into a predetermined shape while applying adhesive at predetermined points. The blank is folded by passing it through a multi-function folding means, including a lifting means which can slightly lift the outside edge of the blank until a belt-like folding and propelling means can then fold one panel of a blank over onto the other panel while adhesive is being applied. The folding operation can be repeated as many times as is needed to form the part.
