ABSTRACT:
Metal, fiber or plastic panels are fabricated by the attachment of planar imperforate and/or partially perforated outer sheets to a specially formed center member comprising a web or sheet having a deformed surface defining an array of adjacent triangular projections and depressions. The center member is produced by the longitudinal cutting and folding of the web as it passes between two forming cylinders which mesh with one another, the cylinder peripheries carrying complementary arrays of spaced triangular-shaped tooth elements having their base lines aligned in the opposing cylinders, to shear and thereby relieve the passing web laterally so as to produce intermittent parallel cuts and angular folds in the web while gathering the web longitudinally thereby to form triangular, flat-topped cells in the center member. Instead of using two outer sheets, the formed center member can be used per se, e.g., as a packing medium, or it can be combined with only one outer sheet to form a single-face product.
