There is disclosed a method and apparatus for continuously making cardboard runners and stringers and assembling them into a cardboard pallet. Whether a runner or stringer is involved, the method involves essentially supplying a fiberboard blank of appropriate composition and size, running the blank through a perforating and scoring roller to produce fold lines in the blank, and progressively folding the blank from the outside in, by passing it through a plurality of curvilinear rods, and applying adhesive to portions of the blank during the folding process. The runners and stringers thus produced are assembled together to form a cardboard pallet.
